特開昭48−35914号公報Japanese Patent Laid-Open No. 48-35914 特開平4−63880号公報Unexamined-Japanese-Patent No. 4-63880 特表平5−501384号公報Japanese Patent Publication No. 5-501384 WO2012/18107A1WO 2012/18107 A1 WO2014/148468A1WO 2014/148468 A1

上記のいずれも、固形描画材で筆記して得られた描線が濃く、また、筆記面への定着性を問題としている。しかし、炭素鋼や玄武岩など、平滑ではない、金属あるいは石材の黒っぽい表面においては、隠蔽性の高い目立つ描線を引くことができず、輪郭のはっきりしない描線となることが問題であった。
そこで本発明は、筆記面としての紙面やコート紙面のみならず金属あるいは岩材の表面上に、隠蔽性の高い輪郭のはっきりした目立つ塗膜を作ることができ、筆記面としての紙面やコート紙面のみならず金属あるいは石材の表面を修正テープのように被覆することができる固形描画材を提供することを課題とする。
In any of the above, the drawing line obtained by writing with a solid drawing material is deep, and the fixability to the writing surface is a problem. However, on black surfaces such as carbon steel and basalt, which are not smooth, metal or stone dark surfaces, it is not possible to draw highly visible lines with high hiding power, and it is a problem that the lines become unclear.
Therefore, the present invention makes it possible to make a clear coating film with a high hiding power and a clear outline on the surface of metal or rock as well as the surface of a sheet of paper or a surface of a sheet of paper as a writing surface. It is an object of the present invention to provide a solid drawing material capable of covering not only the surface of metal or stone but also a correction tape.

上記課題に鑑み、本発明は、ワックスと、体質材と、隠蔽性顔料とを含む固形描画材であって、
さらに、粘着性付与剤と、基材としての融点60〜90℃であるエチレン酢酸ビニル共重合体と、融点30℃以下の潤滑成分と、改質剤と、を含むことを特徴とする。
In view of the above problems, the present invention is a solid drawing material comprising a wax, an extender and a hiding pigment,
Furthermore, it is characterized by including a tackifier, an ethylene-vinyl acetate copolymer having a melting point of 60 to 90 ° C. as a base material, a lubricating component having a melting point of 30 ° C. or less, and a modifier.

本発明における「ワックス」とは、固形描画の構成成分のうち一般的にワックスとして分類されるものをいう。固形描画材の成分としてのワックスは、非使用時には形状保持に寄与するが、力が加えられると速やかに崩壊して筆記時の潤滑性を付与するものである。また、後述の粘着性付与剤と相溶して筆記面への定着性を付与する。このワックスとしては、融点45〜100℃程度で溶融温度が低いものが望ましい。具体的には、パラフィンワックス、マイクロクリスタリンワックス、ウルシロウ、ミツロウ、モクロウ、モンタンワックス、硬化ヒマシ油、パーム硬化油グリセリン脂肪酸エステル、ポリグリセリン脂肪酸エステル等が本発明におけるワックスとして使用可能である。また、その配合量は全体の50重量%以下が望ましい。 The "wax" in the present invention refers to a component of the solid drawing material generally classified as a wax. The wax as a component of the solid drawing material contributes to shape retention when not in use, but it quickly disintegrates when a force is applied to impart lubricity at the time of writing. Further, it is compatible with a tackifier to be described later to impart fixability to the writing surface. The wax preferably has a melting point of about 45 to 100 ° C. and a low melting temperature. Specifically, paraffin wax, microcrystalline wax, Japanese wax, beeswax, beeswax, monk wax, montan wax, hydrogenated castor oil, palm hydrogenated oil glycerin fatty acid ester, polyglycerin fatty acid ester and the like can be used as the wax in the present invention. Moreover, as for the compounding quantity, 50 weight% or less of the whole is desirable.

本発明における「体質材」とは、固形筆記具の強度向上、筆記性向上に寄与する成分である。また、後述の隠蔽性顔料の補助的な作用も発揮する。具体的には、タルク、カオリン、マイカ、窒化ホウ素、炭酸カルシウム、チタン酸カリウムウィスカーなどが本発明における体質材として使用可能である。また、その配合量は全体の5〜40重量%が望ましい。   The “constituent material” in the present invention is a component that contributes to the improvement in the strength and the writing performance of the solid writing instrument. In addition, the auxiliary effect of the hiding pigment described later is also exerted. Specifically, talc, kaolin, mica, boron nitride, calcium carbonate, potassium titanate whiskers and the like can be used as the extender in the present invention. Moreover, as for the compounding quantity, 5 to 40 weight% of the whole is desirable.

本発明における「隠蔽性顔料」とは、この固形描画材により得られた塗膜が、下地を隠蔽することに寄与する成分である。具体的には、二酸化チタンが本発明における隠蔽性顔料として使用可能である。本発明における「二酸化チタン」としてはルチル、アタナーゼを問わず従来公知の二酸化チタンをすべて用いることができる。また、その配合量は全体の5〜40重量%が望ましい。更に好ましくは10〜35重量%が望ましい。この他の隠蔽性顔料としては、酸化亜鉛、カーボンブラック、有機顔料及び着色樹脂顔料等が挙げられるが、隠蔽力等の観点から、二酸化チタンが最も好ましい。描画しようとするものの色によっては、(黒に近い色では)カーボンブラック、(赤色や青色等では)有機顔料、(蛍光色等では)着色樹脂顔料等も適宜選択される。   The "masking pigment" in the present invention is a component that contributes to the coating layer obtained by this solid drawing material from hiding the base. Specifically, titanium dioxide can be used as the hiding pigment in the present invention. As "titanium dioxide" in the present invention, any conventionally known titanium dioxide can be used regardless of rutile or anatase. Moreover, as for the compounding quantity, 5 to 40 weight% of the whole is desirable. More preferably, 10 to 35% by weight is desirable. Other hiding pigments include zinc oxide, carbon black, organic pigments, colored resin pigments and the like, but titanium dioxide is most preferable from the viewpoint of hiding power and the like. Depending on the color of the object to be drawn, carbon black (for colors close to black), organic pigments (for red and blue, etc.), colored resin pigments (for fluorescent colors etc.), etc. are also selected appropriately.

本発明における「粘着性付与剤」とは、固形描画材による描線の、筆記面への定着性を向上させる目的で用いられる。
さらに、前記粘着性付与剤は、テルペン樹脂、テルペン樹脂変性物、マレイン酸樹脂誘導体、クマロン・インデン樹脂、クマロン・インデン樹脂誘導体、スチレン系樹脂、イソプレン系樹脂、松脂、ロジンエステル及び石油樹脂から成る群から選ばれる1つ又は2以上の混合物であることが望ましい。具体的にはテルペンフェノール樹脂、水添テルペンフェノール樹脂、水添テルペン樹脂、芳香族変性水添テルペン樹脂、芳香族変性テルペン樹脂などのテルペン樹脂変性物の使用が更に望ましい。また、この粘着性付与剤の配合量としては、1〜10重量%が望ましい。
The "tackifier" in the present invention is used for the purpose of improving the fixability to the writing surface of the drawing line by the solid drawing material.
Furthermore, the tackifier comprises terpene resin, terpene resin modified product, maleic acid resin derivative, coumarone-indene resin, coumarone-indene resin derivative, styrenic resin, isoprene resin, rosin ester, rosin ester and petroleum resin It is desirable that it is a mixture of one or more selected from the group. Specifically, the use of terpene resin modified products such as terpene phenol resin, hydrogenated terpene phenol resin, hydrogenated terpene resin, aromatic modified hydrogenated terpene resin, aromatic modified terpene resin and the like is more desirable. Moreover, as a compounding quantity of this tackifier, 1-10 weight% is desirable.

本発明における「エチレン酢酸ビニル共重合体」とは、本発明の固形描画具の基材をなすものである。非使用時には基材として固形筆記具に柔軟性を与え形状保持に寄与する。また、筆記時には筆記面との摩擦熱により塗膜状に摩耗し筆記面に固着することにより、隠蔽性に寄与することとなる。また、この成分は、被膜をこの固形筆記具自身で擦過することで細かく破砕されて除去されてしまう、いわゆる「自己消去性」の発揮にも寄与するものである。これらの性質を発揮すべく、このエチレン酢酸ビニル共重合体は、融点が60〜90℃のものが使用される。また、このエチレン酢酸ビニル共重合体はJIS K7210:1999で定めるメルトフローレートが400〜3,000g/10minである。また、このエチレン酢酸ビニル共重合体の配合量としては5〜20重量%である。また、このエチレン酢酸ビニル共重合体は、酢酸ビニルモノマーを10重量%以上の割合で重合させたものであることが望ましい。   The "ethylene vinyl acetate copolymer" in the present invention is a base material of the solid image drawing tool of the present invention. When not in use, it gives flexibility to a solid writing instrument as a base material and contributes to shape retention. In addition, when writing, it wears in the form of a coating film by frictional heat with the writing surface and adheres to the writing surface, which contributes to the concealability. Further, this component also contributes to the so-called "self-erasing property" in which the coating is finely crushed and removed by rubbing the solid writing tool itself. In order to exert these properties, the ethylene-vinyl acetate copolymer having a melting point of 60 to 90 ° C. is used. The ethylene vinyl acetate copolymer has a melt flow rate of 400 to 3,000 g / 10 min as defined in JIS K 7210: 1999. Moreover, as a compounding quantity of this ethylene vinyl acetate copolymer, it is 5 to 20 weight%. The ethylene-vinyl acetate copolymer is preferably obtained by polymerizing a vinyl acetate monomer in a proportion of 10% by weight or more.

本発明における「潤滑成分」は、潤滑性付与を目的とした成分である。この潤滑成分の融点は30℃以下である。このような成分としては、ホホバ油、流動パラフィン、スクワラン、スクワレン、流動パラフィン等のオイル類が挙げられる。また、この潤滑成分の配合量は5〜2重量%が望ましい。 The "lubricant component" in the present invention is a component for the purpose of imparting lubricity. The melting point of this lubricating component is 30 ° C. or less. Examples of such components include oils such as jojoba oil, liquid paraffin, squalane, squalene, liquid paraffin and the like. The amount of the lubricating component is preferably 5 to 2 2 wt%.

本発明における「改質剤」は、滑りやすい非吸収面などへの塗布に際し、上滑りせずに塗布できるようにすることを目的として添加する成分である。具体的には、二塩基酸及びその誘導体を本発明における改質剤として使用できる。本発明における二塩基酸及びその誘導体としては、ドデカン二酸、オクタデカン二酸、エイコサン二酸、オクタコサン二酸、エイコサン二酸ジメチル、8−エチルオクタデカン二酸、8,13−ジメチルエイコサン二酸、8,12−エイコサジエン二酸ジメチル、8,13−ジメチル−8,12−エイコサジエン二酸ビス(オキシラニルメチル)エステル、日本酸グリセリドなどの少なくとも1種(各単独、または2種以上の混合物)等を用いることができる。更に好ましくは、8−エチルオクタデカン二酸、8,12−エイコサジエン二酸ジメチル、日本酸グリセリドである。なお、日本酸は炭素数20(C20)、22(C22)の二塩基酸(混合物)であり、日本酸グリセリドは2分子のグリセリンに二塩基酸が橋かけ的に結合した二分子型グリセリドであり、その合成法などは既知である。また、この二塩基酸及びその誘導体の配合量としては1〜6.4重量%が望ましい。 The "modifier" in the present invention is a component added for the purpose of enabling application without slippage when applied to a slippery non-absorbing surface or the like. Specifically, dibasic acids and their derivatives can be used as modifiers in the present invention. As the dibasic acid and derivatives thereof in the present invention, dodecanedioic acid, octadecanedioic acid, eicosanedioic acid, octacosanedioic acid, dimethyleicosane diacid, 8-ethyloctadecanedioic acid, 8,13-dimethyleicosanedioic acid, Dimethyl 8,12-eicosadiene diacid, 8,13-dimethyl-8,12-eicosadiene diacid bis (oxiranylmethyl) ester, at least one such as Japanese acid glyceride (each alone or a mixture of two or more) Etc. can be used. More preferable are 8-ethyloctadecanedioic acid, dimethyl 8,12-eicosadienedioate, and Japanese acid glyceride. Nippon acid is a dibasic acid (mixture) of carbon number 20 (C20) and 22 (C22), and Japanese acid glyceride is a bimolecular glyceride in which dibasic acid is cross-linked to two molecules of glycerin. Yes, their synthesis methods etc. are known. Moreover, as a compounding quantity of this dibasic acid and its derivative (s), 1 to 6.4 weight% is desirable.

なお、本発明においては、塗膜の隠蔽性を向上させ、輪郭のはっきりした目立つ塗膜を作ることに寄与する成分として、「顔料分散剤」をさらに含むことが望ましい。具体的には、高分子アミン化合物等のカチオン系のポリマー、高分子ポリカルボン酸及びそれらの塩等のアニオン系のポリマー、ポリエチレングリコールの誘導体等のノニオン系のポリマー等を好適に用いることができると考えられる。なお、上記隠蔽性顔料に吸着し、上記ワックスと相溶するものであれば制限なく用いることができる。また、その配合量は上記隠蔽性顔料100に対して1〜10、具体的な量としては0.05〜4重量%が望ましい。更に好ましくは上記隠蔽性顔料100に対して2〜5、具体的な量としては0.1〜2重量%が望ましい。この顔料分散剤を添加することで、製造工程において溶融した組成物の粘度を下げるため、製造コストを下げることができる。この顔料分散剤は、上記の通り比重の大きな隠蔽性顔料を液体中に分散安定化させる効果はあるものの、隠蔽性の向上、輪郭のはっきりした塗膜の形成といった効果を大きく発揮できるわけではないので、さほどの量を必要としないか場合によっては添加の必要のないものと考えられる。   In the present invention, it is desirable to further include a "pigment dispersant" as a component contributing to the improvement of the hiding power of the coating film and the formation of a coating film having a sharp and distinct profile. Specifically, cationic polymers such as polymeric amine compounds, anionic polymers such as polymeric polycarboxylic acids and salts thereof, and nonionic polymers such as derivatives of polyethylene glycol can be suitably used. it is conceivable that. In addition, if it adsorb | sucks to the said concealing pigment and it is compatible with the said wax, it can be used without a restriction | limiting. In addition, the compounding amount thereof is desirably 1 to 10, specifically 0.05 to 4% by weight based on 100 of the above-mentioned hiding pigment. More preferably, 2 to 5 and specifically 0.1 to 2% by weight are desirable based on 100 as the hiding pigment. By adding this pigment dispersant, the viscosity of the composition melted in the production process can be lowered, and therefore the production cost can be lowered. Although this pigment dispersant has the effect of dispersing and stabilizing the hiding pigment having a large specific gravity in the liquid as described above, it can not largely exhibit the effects such as the improvement of the hiding property and the formation of a well-defined coating film. Therefore, it may be considered as not necessary to add a small amount or in some cases.

なお、この「顔料分散剤」の外に、さらに所謂「濡れ剤」を用いることで、塗膜の隠蔽性をより向上させ、輪郭のはっきりした目立つ塗膜を作ることが可能となる。具体的には、上記隠蔽性顔料の吸着を助け、上記顔料分散剤の効果を阻害しないものであれば制限なく用いることができる。例えば、ポリオキシアルキレンエーテル等の界面活性剤をこの濡れ剤として好適に用いることができると考えられる。   In addition to the "pigment dispersant", by further using a so-called "wetting agent", it is possible to further improve the hiding power of the coating film, and to make a conspicuous coating film with a sharp outline. Specifically, it can be used without limitation as long as it helps the adsorption of the hiding pigment and does not inhibit the effect of the pigment dispersant. For example, it is believed that surfactants such as polyoxyalkylene ethers can be suitably used as the wetting agent.

本発明に係る固形描画材は、上記のように構成されているので、隠蔽性が高く、筆記面としてのPET、ガラス及びSUSの表面だけでなく、金属あるいは石材の表面にも、隠蔽性の高い輪郭のはっきりした目立つ塗膜を作ることができる。
また、成分として揮発成分を含まないため、外部に紙巻きをしたり、ホルダーに収容したり、また、キャップを装着したりすることが不要であり、裸芯のまま直接手指で保持してもベタついたりすることはない。さらに、特にホルダー等の補強手段を設けずとも、裸芯の状態で筆記するのに十分な強度を有することともなっている。
Since the solid drawing material according to the present invention is configured as described above, it has high concealability, and it has concealability not only on the surface of PET, glass and SUS as a writing surface but also on the surface of metal or stone. It is possible to make a high-profile, clear and conspicuous coating film.
Moreover, since it does not contain a volatile component as a component, it is not necessary to wind a paper outside, to store in a holder, and to attach a cap, and even if it holds directly with fingers, it is solid There is no need to follow. Furthermore, even without providing reinforcing means such as a holder in particular, it is also required to have sufficient strength for writing in the state of a bare core.

(2−5)評価結果   (2-5) Evaluation results

上記の表1の通り、本発明の実施例1〜4、比較例7、実施例6〜8、比較例8及び実施例10〜12に係る固形描画材は、PETフィルム面、ガラス面、SUS表面及び玄武岩粗面に対する筆記性について良好な結果を示した。すなわち、隠蔽性が高く、筆記面としてのPETフィルム面、ガラス面、SUS表面及び玄武岩粗面を被覆することが可能な固形描画であった。ただし、潤滑成分の含有量が他よりも多かった実施例10についてのみ、250℃の高温になったSUS表面に対する筆記性に劣るものであった。 As described above in Table 1, the solid drawing materials according to Examples 1 to 4 of the present invention , Comparative example 7, Examples 6 to 8 and Comparative examples 8 and 10 to 12 are PET film surface, glass surface, SUS Good results are shown for the writeability to the surface and basalt rough surface. That is, it was a solid drawing material having high hiding power and capable of covering a PET film surface as a writing surface, a glass surface, a SUS surface, and a rough basalt surface. However, the writability with respect to the SUS surface which became high temperature of 250 degreeC was inferior only about Example 10 which had content of the lubricating component more than others.

上記の表2の通り、定着性については、実施例1〜4、比較例7、実施例6〜8、比較例8及び実施例10〜12のうち実施例7と10を除く固形描画材については、良好な結果を示した。つまり、これらの実施例に係る固形描画材は、PETフィルム面、ガラス面、SUS表面及び玄武岩粗面に形成された塗膜を手指などで擦過しても除去されることがない。一方、実施例7に係る固形描画材は粘着性付与材の含有量が他よりも少ないため、筆記面に形成された塗膜を維持する力が弱く、定着性に劣るものとなったと推測された。また、実施例10に係る固形描画材は潤滑成分の含有量が22重量%と他よりも極端に多いため、筆記面に形成された塗膜と筆記面との間に摩擦力が働かず、塗膜を維持する力が弱く、定着性に劣るものとなったと推測された。 As shown in Table 2 above, with regard to the fixability, the solid drawing materials except Examples 7 and 10 among Examples 1 to 4, Comparative Example 7, Examples 6 to 8, Comparative Examples 8 and 10 to 12 Showed good results. That is, the solid drawing material according to these examples is not removed even when the coating film formed on the PET film surface, the glass surface, the SUS surface and the basalt rough surface is abraded with a finger or the like. On the other hand, the solid drawing material according to Example 7 has a smaller content of the tackifier than the others, and therefore, it is estimated that the ability to maintain the coating film formed on the writing surface is weak and the fixing property is poor. The In addition, since the solid drawing material according to Example 10 has a lubricating component content of 22% by weight, which is extremely higher than the others, no frictional force acts between the coating film formed on the writing surface and the writing surface, It was speculated that the ability to maintain the coating was weak and that the fixability was poor.

また、上記表2の通り、折損強度は、実施例1〜3、比較例7実施例7、比較例8実施例11及び12に係る固形描画材については良好な結果を示した。これらの固形描画材の折損強度は、通常の使用で折れる場合があるものの、棒状体の表面に保護層を設けて強化を行わなくても実用に耐えうる程度であった。つまり、保護層を設けなくてもよいので、保護層を取り除く作業を必要としない、作業場で、すぐに使用可能な固形描画材とすることができる。一方、実施例4、6、8及び10に係る固形描画材は、分散材、改質剤、粘着性付与材及び潤滑成分のうちいずれか一つの成分が過多であり、これによって折損強度が低下したものと推測された。 Further, as shown in Table 2 above, the breaking strength showed good results for the solid drawing materials according to Examples 1 to 3, Comparative Example 7 , Example 7, Comparative Example 8 and Examples 11 and 12. Although the breaking strength of these solid drawing materials may be broken in normal use, they were practically acceptable even if they were not reinforced by providing a protective layer on the surface of the rod-like body. That is, since it is not necessary to provide a protective layer, it can be set as the solid drawing material which can be used immediately at the workplace which does not require the operation of removing the protective layer. On the other hand, in the solid drawing materials according to Examples 4, 6, 8 and 10, any one component among the dispersing agent, the modifier, the tackifier and the lubricating component is excessive, thereby lowering the breaking strength. It was guessed that it was done.

改質剤の含有量が1.0重量%よりも少ない比較例7に係る固形描画材においては、筆記性が実施例1及び2と比べて劣るものであった。改質剤が少ないために、筆記面上を上滑りしてしまったと推測された。
顔料分散剤及び濡れ剤が添加されていない実施例12に係る固形描画材においては、SUS表面及び玄武岩粗面に対する筆記性は、実施例1及び2と比べて劣るものとなった。
濡れ剤が添加されていない実施例11に係る固形描画材においては、耐熱筆記性及び玄武岩粗面に対する定着性は実施例1及び2と比べて劣るものとなった。
隠蔽性顔料100に対して顔料分散材が1よりも少ない実施例3においては、SUS表面及び玄武岩粗面上に対する筆記性が、実施例1及び2と比べ劣るものとなった。これは、顔料分散剤が隠蔽性顔料に対して少なく、隠蔽性顔料に吸着した顔料分散材が少なく、隠蔽性顔料が十分に分散せず、隠蔽性が得られる部分とそうでない部分とが生じ、描線に乱れが生じたもの推測された。
In the solid drawing material according to Comparative Example 7 in which the content of the modifier was less than 1.0% by weight, the writability was inferior to Examples 1 and 2. It was surmised that the writing surface had slipped up due to the low amount of modifier.
In the solid drawing material according to Example 12 in which the pigment dispersant and the wetting agent were not added, the writability to the SUS surface and the basalt rough surface was inferior to those in Examples 1 and 2.
In the solid drawing material according to Example 11 in which the wetting agent was not added, the heat-resistant writing property and the fixing property to the basalt rough surface were inferior to those in Examples 1 and 2.
In Example 3 in which the pigment dispersant was less than 1 with respect to the hiding pigment 100, the writability on the SUS surface and basalt rough surface was inferior to that in Examples 1 and 2. This is because the pigment dispersant is less than the hiding pigment, the pigment dispersing material adsorbed to the hiding pigment is less, the hiding pigment is not sufficiently dispersed, and a part where the hiding property is obtained and a part where it does not occur. , it has been estimated that there is a disturbance in the drawn lines.

これに対し、本発明の範囲外である比較例1〜5の試験結果は、PETフィルム、ガラス、SUS表面及び玄武岩粗面への筆記性が劣るものであり、そのため定着性の評価においても、劣るものとなった。
まず、比較例1は顔料分散剤及び濡れ剤は配合されているものの、粘着性付与剤と改質剤が配合されていないため、塗膜が形成されれば目立つものの、塗膜を形成し、筆記面上に粘着させる力に劣るため、筆記性に劣り、定着力も低いものと推測された。
比較例2は粘着性付与剤が配合されていないため、PETフィルム、ガラス、SUSの表面及び玄武岩粗面に輪郭のはっきりした目立つ塗膜を粘着させることができず、当然、隠蔽性も劣るものであると推測された。
On the other hand, the test results of Comparative Examples 1 to 5 which are out of the scope of the present invention are inferior in the writing property to the PET film, glass, SUS surface and basalt rough surface, and therefore in the evaluation of fixing property, It became inferior.
First, in Comparative Example 1, although the pigment dispersant and the wetting agent are blended, since the tackifier and the modifier are not blended, the coating film is formed although it is noticeable if the coating film is formed, Since it was inferior to the power to make it stick on a writing surface, it was estimated that it was inferior to writing performance and that fixing power was also low.
Comparative Example 2 does not contain a tackifier, so it is not possible to adhere a prominent coating film having a clear outline to the surface of PET film, glass, SUS and basalt rough surface, and of course, the concealability is also inferior Was guessed to be.

比較例3は、改質剤が配合されていないため、表面がやや粗いSUS表面及び玄武岩粗面に塗膜を粘着させて形成させる力はあるものの、平滑面であるPETフィルム面及びガラス表面上は滑ってしまうため筆記性に劣るものと推測された。
比較例4は、潤滑剤としての流動パラフィンが配合されていないため、非吸収面上について粘着させ塗膜を形成させる力が弱く、そのため定着力も低いと推測された。
比較例5は、配合するEVAのメルトフローレートが6g/10minと低く、塗膜をPETフィルム、ガラスの表面に粘着させ塗膜を形成させる力はあり、それなりに定着力を発揮されるものの、SUS表面及び玄武岩粗面への筆記性に劣るものと推測された。
Comparative Example 3 does not contain a modifier, so it has a force to cause the coating to adhere to the SUS surface and the basalt rough surface with a slightly rough surface, but on the PET film surface and the glass surface that are smooth surfaces Because it slips, it is presumed that it is inferior to writing.
In Comparative Example 4, since the liquid paraffin as a lubricant was not blended, it was assumed that the force for causing the film to adhere and form a film on the non-absorbing surface was weak, and therefore the fixing ability was also low.
In Comparative Example 5, the melt flow rate of EVA to be blended is as low as 6 g / 10 min, and the coating film is made to adhere to the surface of the PET film and glass to form a coating film, and the fixing power is exhibited accordingly It was speculated that the writability to the SUS surface and basalt rough surface was inferior.

比較例6は、EVAの代わりにロジンエステルが配合され、粘着性付与剤、改質剤(二塩基酸及びその誘導体)、潤滑成分、顔料分散剤、濡れ剤及び粘着性付与剤が配合されていなかったため、PETフィルム面、ガラス面、SUS表面及び玄武岩粗面に粘着し塗膜を形成させることができなかったものと推測された。   In Comparative Example 6, instead of EVA, a rosin ester is blended, and a tackifier, modifier (dibasic acid and its derivative), lubricating component, pigment dispersant, wetting agent, and tackifier are blended. Since it did not exist, it was speculated that the film could not be formed by sticking to the PET film surface, glass surface, SUS surface and basalt rough surface.

本発明は、ワックスと、体質材と、隠蔽性顔料と、基材としてのEVA樹脂、潤滑成分と、顔料分散剤とを固形に成形してなる、PET、ガラス、SUSの表面及び玄武岩粗面への筆記が可能なクレヨンやクレパスのような固形描画材として利用可能である。   In the present invention, the surface of a PET, glass, SUS, and basalt rough surface formed by solidifying a wax, an extender, a hiding pigment, an EVA resin as a base material, a lubricating component, and a pigment dispersant. It can be used as a solid drawing material such as crayons and crepas that can be written on.
