Description

  The present invention relates to a transfer film for a writing tool, a method for manufacturing a transfer film for a writing tool, a writing tool, and a method for manufacturing the writing tool.

  Writing tools such as pencils tend to slip when the gripping surface is smooth, and may cause fatigue when used for a long time. For this reason, the grip surface of the writing tool may be subjected to anti-slip processing. Conventionally, such anti-slip processing has been performed by a method of applying a paint to form a coating film having a rubber feel or a method of coating a foaming resin.

  However, the conventional method has a problem that the flexibility of the design of the writing tool cannot be increased and the writing tool cannot be easily manufactured. Therefore, in Patent Document 1, a transfer film composed of a base material and a transfer portion in which a non-slip layer made of a polyurethane resin and an adhesive resin layer are laminated is used, and the transfer portion is provided on the grip surface of the writing instrument. It is described that the gripping surface of the writing tool is subjected to non-slip processing by transferring.

[Brush 1]
A writing instrument 1 according to an embodiment of the present invention will be described with reference to FIG. 1. FIG. 1 is a perspective view of a writing instrument 1 according to an embodiment of the present invention. As shown in FIG. 1, the writing instrument 1 includes a writing instrument main body 10 and a transfer unit 20 that is transferred to the writing instrument main body 10 and covers at least a part of a surface 10s of the writing instrument main body.

  In the present specification, the term writing tool 1 is used as a concept including a writing tool including the illustrated pencil, a brush for applying cosmetics, chemicals, paints, and the like, and an applicator such as a brush. Therefore, the writing instrument main body portion 10 refers to a shaft portion that functions as a writing portion or a coating portion. The same elements will be denoted by the same reference numerals throughout the specification.

  The transfer portion 20 is provided so as to cover the entire surface or a part of the surface 10s of the writing instrument main body. The transfer unit 20 includes a non-slip rubber layer 22 on the surface 20 s of the transfer unit on the non-contact surface side of the writing instrument body 10. As a result, the non-slip rubber layer 22 is arranged on the grip surface of the writing instrument 1. The non-slip rubber layer 22 may have a rubber layer pattern portion 22a on the non-contact surface side of the writing instrument body portion 10, or may have no rubber layer pattern portion 22a but a smooth rubber layer base portion 22b described later. May be When there are a plurality of rubber layer pattern portions 22a, it is possible to add a pattern to the surface 20s of the transfer portion, that is, the grip surface of the writing instrument 1. The writing tool 1 is formed by transferring the transfer section 20 to the writing tool main body 10 using a writing tool transfer film 2 described below.

[Transfer film for brushes 2]
The brush transfer film 2 of the present embodiment will be described with reference to FIGS. 2 and 3. FIG. 2 is a plan view of the transfer film 2 for a writing instrument according to the embodiment of the present invention, and FIG. 3 is a cross-sectional view taken along the line XX ′ of FIG. The brush transfer film 2 includes a transfer section 20 and a peeling section 30 on the side of the anti-slip rubber layer to which the transfer section 20 is fixed. The transfer part 20 is provided between the non-slip rubber layer 22, the adhesive resin layer 28 arranged so as to face the anti-slip rubber layer 22, and between the anti-slip rubber layer 22 and the adhesive resin layer 28. The organic solvent impermeable resin layer 26 for blocking the passage of the organic solvent from the side of the permeable resin layer 28 to the side of the non-slip rubber layer 22.

  As a result, the transfer film 2 for a writing tool of the present invention can easily form a slip stopper on the grip surface of the writing tool 1, and can be used in combination with an organic solvent or an adhesive contained in the material for forming the adhesive resin layer 28 during manufacturing. The organic solvent remaining in the flexible resin layer 28 is less likely to cause wrinkles, whitening, or partial peeling of the anti-slip rubber layer 22, and allows accurate transfer to the writing instrument 1. That is, by containing the organic solvent impermeable resin layer 26 that blocks the passage of the organic solvent from the adhesive resin layer 28 side to the non-slip rubber layer 22 side, the swelling of the thin film anti-slip rubber layer 22 is contained. And the occurrence of wrinkles, whitening and partial peeling on the anti-slip rubber layer 22 is suppressed.

  The transfer section 20 is fixed to the front surface 10s of the writing instrument main body section by the adhesive resin layer 28 contained on the back surface 20b side of the transfer section. The thickness of the transfer portion 20 can be 10 μm or more and 35 μm or less. As a result, the transfer unit 20 can sufficiently prevent the writing tool 1 from slipping, and can prevent the adhesiveness of the transfer unit 20 from decreasing or the transfer pressure of the transfer unit 20 from varying.

  The organic solvent impermeable resin layer 26 is provided between the adhesive resin layer 28 and the non-slip rubber layer 22, and prevents the organic solvent from passing from the adhesive resin layer 28 side to the non-slip rubber layer 22 side. It is a resin layer for blocking. The organic solvent impermeable resin layer 26 is a layer containing a resin as a main component. The organic solvent impermeable resin layer 26 is preferably provided in contact with at least a part of the anti-slip rubber layer 22. This is because the influence of the organic solvent on the anti-slip rubber layer 22 can be reduced more effectively. Further, the organic solvent impermeable resin layer 26 is preferably provided over the entire surface between the adhesive resin layer 28 and the non-slip rubber layer 22.

  The material of the organic solvent impermeable resin layer 26 differs depending on the type of the organic solvent, but for example, a thermosetting resin, an ultraviolet curable resin, an electron beam curable resin, a radiation curable resin which is cured by a curing treatment. A resin or the like may be contained as a main component. Among them, the organic solvent impermeable resin layer 26 may contain the ultraviolet curable resin as a main component and not the organic solvent. Thereby, the influence of the organic solvent on the anti-slip rubber layer 22 is further reduced, the organic solvent impermeable resin layer 26 is formed in a short time, and the influence on other layers due to the curing treatment can be reduced. is there. The material of the organic solvent impermeable resin layer 26 is such that the swelling resistance of the organic solvent impermeable resin layer 26 to the adhesive resin layer 28 or the organic solvent contained in the adhesive resin material is the adhesive resin layer 28 or the adhesive property. It is selected so as to have a higher swelling resistance of the non-slip rubber layer 22 with respect to the organic solvent contained in the resin material. For example, when the adhesive resin layer 28 or the adhesive resin material contains a hydrocarbon solvent such as toluene or hexane, an ester solvent, or a ketone solvent as the organic solvent, the organic solvent impermeable resin layer 26 is Polymer of urethane acrylate monomer, polymer of urethane acrylate oligomer, polymer of polyfunctional acrylate monomer, polymer of polyfunctional acrylate oligomer, polymer of epoxy acrylate monomer, polymer of epoxy acrylate oligomer, polyester acrylate monomer At least one selected from the group consisting of a polymer and a polymer of a polyester acrylate oligomer can be included.

  The surface 26s of the organic solvent impermeable resin layer may be roughened, and the adhesive resin layer 28 may be provided in contact with the surface 26s of the organic solvent impermeable resin layer. When the organic solvent resistance of the organic solvent impermeable resin layer 26 increases, the adhesion between the organic solvent impermeable resin layer 26 and the adhesive resin layer 28 decreases. Therefore, the roughened surface suppresses the decrease in adhesion between the organic solvent impermeable resin layer 26 and the adhesive resin layer 28, and serves as a part of the transfer portion 20. The adhesiveness between the impermeable resin layer 26 and the adhesive resin layer 28 is improved. As a result, the surface roughness of the surface 26s of the organic solvent impermeable resin layer may be larger than the surface roughness of the back surface 26b facing the surface 26s of the organic solvent impermeable resin layer.

  The anti-slip rubber layer 22 is a layer that functions as an anti-slip on the grip surface of the writing instrument 1.

  When the transfer film 2 for a writing implement is a transfer film for a writing implement that is transferred to the grip surface of a writing implement such as a pencil, the thickness of the anti-slip rubber layer 22 can be 0.5 μm or more and 20 μm or less. As a result, a sufficient anti-slip function can be imparted to the grip surface of the writing instrument, and the occurrence of uneven thickness of the anti-slip rubber layer 22 can be suppressed. When such a thin film anti-slip rubber layer 22 is swollen by the organic solvent contained in the adhesive resin layer 28, wrinkles, whitening, and partial peeling are likely to occur. Therefore, according to the present invention, the occurrence of wrinkles, whitening, and partial peeling of the writing instrument transfer film can be effectively suppressed, and the transfer section 20 can be accurately transferred to the writing instrument 1.

  The non-slip rubber layer 22 may have a plurality of rubber layer pattern portions 22a formed in a pattern on the surface. For example, the non-slip rubber layer 22 may have a plurality of dot-shaped rubber layer pattern portions 22a arranged in a staggered pattern as shown in FIG. FIG. 6 is a plan view of the writing tool transfer films 2a and 2b according to the modification of the embodiment of the present invention. As shown in FIG. 6B, the writing tool transfer film 2b has a non-slip surface. The rubber layer 22 may have a plurality of strip-shaped rubber layer protrusions 22c arranged in parallel. Further, as shown in FIG. 6A, the transfer film 2a for a writing instrument may not have the rubber layer pattern portion 22a and may have only the rubber layer base portion 22b.

  The anti-slip rubber layer 22 may contain an ultraviolet curable rubber as a main component. As a result, the anti-slip rubber layer 22 can be formed thick, the anti-slip function can be sufficiently imparted to the writing instrument 1, and wrinkles, whitening, or partial peeling may occur on the anti-slip rubber layer 22. It can be further suppressed.

  The adhesive resin layer 28 is formed by applying an adhesive resin material containing a transfer adhesive resin and an organic solvent, and then performing at least one of drying, cooling and curing treatments as needed. .. The curing treatment is applied to a curable coating film of a thermosetting resin, an ultraviolet curable resin, an electron beam curable resin, a radiation curable resin or the like. The adhesive resin layer 28 may contain a residual organic solvent. The thickness of the adhesive resin layer 28 can be in the range of 0.1 μm or more and 5 μm or less.

  As the transfer adhesive resin, acrylic resin, vinyl chloride resin, vinyl acetate resin, vinyl chloride-vinyl acetate copolymer resin, styrene-acrylic copolymer resin, polyester resin, polyamide resin, epoxy resin, isocyanate Type resin, silicone type resin, styrene-butadiene type resin, ethylene-vinyl acetate type resin, polyester type resin, chlorinated rubber type resin, chlorinated polypropylene type resin, urethane type resin The thing which consists of the above can be illustrated.

The adhesive resin material may contain additives such as a thickener, a plasticizer, a pigment, a dye, a film forming agent and an auxiliary agent.

  The combination of the adhesive resin layer 28 or the organic solvent contained in the adhesive resin material, the anti-slip rubber layer 22 and the organic solvent impermeable resin layer 26 is the same as the organic solvent contained in the adhesive resin layer 28 or the adhesive resin material. It differs depending on the type and the materials of the organic solvent impermeable resin layer 26 and the non-slip rubber layer 22. Further, the lower the swelling resistance of the anti-slip rubber layer 22 with respect to the organic resin contained in the adhesive resin layer 28 or the adhesive resin material, the greater the effect of the organic solvent impermeable resin layer 26. For example, when the non-slip rubber layer 22 contains at least one of isoprene rubber and butadiene rubber, the organic solvent contained in the adhesive resin layer 28 is toluene, hexane, isooctane, isopropyl ether, benzyl benzoate, ethylbenzene, epichlorohydrin, xylene. , Kerosene, mineral oil, acetic acid, acetic acid ester, diisopropyl ketone, cyclohexanol, cyclohexane, diethyl ether, cellosolve, tetrahydrofuran, tetrachloroethane, tetralin, hexane, pyridine, etc., suppresses poor appearance due to the organic solvent impermeable resin layer 26. And the effect of suppressing peeling is increased. In this case, the organic solvent impermeable resin layer 26 is a polymer of urethane acrylate monomer, polymer of urethane acrylate oligomer, polymer of polyfunctional acrylate monomer, polymer of polyfunctional acrylate oligomer, polymer of epoxy acrylate monomer, It may include at least one selected from the group consisting of a polymer of epoxy acrylate oligomer, a polymer of polyester acrylate monomer, and a polymer of polyester acrylate oligomer.

When mineral oil, acetic acid, acetic acid ester, diisopropyl ketone, diethyl ether, cellosolve, dioxane, phenol, hexane, pyridine, etc. are used, the effect of suppressing appearance defects and peeling suppression by the organic solvent impermeable resin layer 26 becomes large. Also in this case, the organic solvent impermeable resin layer 26 is formed of a polymer of urethane acrylate monomer, a polymer of urethane acrylate oligomer, a polymer of polyfunctional acrylate monomer, a polymer of polyfunctional acrylate oligomer, a polymer of epoxy acrylate monomer. At least one selected from the group consisting of a polymer of epoxy acrylate oligomer, a polymer of polyester acrylate monomer, and a polymer of polyester acrylate oligomer.

The transfer film 2e for a writing tool is formed by laminating a plurality of transfer parts 20 and a peeling part 30 on the non-slip rubber layer side. As shown in FIG. 7, when the transfer portion 20 is provided with an outer shape larger than that of the transfer portion 20, the peeling portion 30 on the anti-slip rubber layer side can be peeled more easily, and a plurality of transfer portions 20 can be easily transported. can do.
