Can be blended.
［アクリル樹脂系エマルジョン（Ａ）］
本発明に使用するアクリル樹脂系エマルジョン（Ａ）は、アクリレートモノマーを含む、アクリル酸、メタクリル酸、マレイン酸、フマル酸、イタコン酸等の不飽和カルボン酸、及びこれらのモノエステルや、スチレン、α−メチルスチレン、ビニルトルエン、クロロスチレン等のスチレン類、酢酸ビニル等のビニルエステル類、メチルビニルエーテル、エチルビニルエーテル、ブチルビニルエーテル等のビニルエーテル類などの不飽和基含有重合性単量体の重合によって合成され，アクリル酸エステル系共重合樹脂、酢酸ビニル・アクリル酸エステル系共重合樹脂、シリコン変性アクリル系樹脂等の水性アクリル樹脂系エマルジョンが使用できる。本発明の漆黒水系塗材組成物全体中の樹脂固形分は１．０〜１５．０重量％が好ましく、１．０重量％未満では粘着性、塗付作業性が低下し、また１５．０重量％超では粘度が低下し塗付作業性が低下すると共に表現できる意匠（パターン）数が低下する。市販のアクリル樹脂系エマルジョン（Ａ）としては、アクロナールＰＳ７４３（ＢＡＳＦ社製、固形分５５重量％）がある。
[Acrylic resin emulsion (A)]
The acrylic resin emulsion (A) used in the present invention is an unsaturated carboxylic acid such as acrylic acid, methacrylic acid, maleic acid, fumaric acid or itaconic acid containing an acrylate monomer, and monoesters thereof, styrene and α. -Synthesized by polymerizing unsaturated group-containing polymerizable monomers such as styrenes such as methylstyrene, vinyltoluene and chlorostyrene, vinyl esters such as vinyl acetate, vinyl ethers such as methyl vinyl ether, ethyl vinyl ether and butyl vinyl ether. Aqueous acrylic resin emulsions such as acrylic ester copolymer resins, vinyl acetate/acrylic ester copolymer resins, and silicone-modified acrylic resins can be used. The resin solid content in the entire jet black water-based coating material composition of the present invention is preferably 1.0 to 15.0% by weight, and when it is less than 1.0% by weight, tackiness and coating workability are lowered, and 15.0% by weight. When the content is more than wt%, the viscosity is lowered, the coating workability is lowered, and the number of designs (patterns) that can be expressed is lowered. As a commercially available acrylic resin emulsion (A), there is ACRONAL PS743 (manufactured by BASF, solid content 55% by weight).
［平均粒径１００μｍ以上の骨材（Ｂ）］
本発明に使用する平均粒径１００μｍ以上の骨材（Ｂ）は，本漆黒水系塗材組成物の仕上がり表面に凹凸を付与することを目的として配合されるが，平均粒径が１００μｍ以上であればその粒子径は任意に選択することができ，例えば硅砂，ガラス，シリカ，タルク，重質炭酸カルシウムなどが使用可能である。なお本願で言う平均粒径とは重量による積算分率５０％の粒子径を言う。市販の平均粒径が２００μｍの重質炭酸カルシウムとしてはＫ−２５０（商品名，旭鉱末（株）製）がある。骨材（Ｂ）の配合量は漆黒水系塗材組成物全体に対して４０〜６５重量％であり４０重量％未満では意匠性（塗材の凹凸感）が不足し，６５重量％超では作業性が低下する。
[Aggregate (B) with an average particle size of 100 μm or more]
The aggregate (B) having an average particle size of 100 μm or more used in the present invention is blended for the purpose of giving unevenness to the finished surface of the jet-black water-based coating material composition, but the average particle size is 100 μm or more. For example, the particle size can be arbitrarily selected, and for example, silica sand, glass, silica, talc, ground calcium carbonate, etc. can be used. It should be noted that the average particle diameter referred to in the present application means a particle diameter with an integrated fraction of 50% by weight. As a commercially available heavy calcium carbonate having an average particle size of 200 μm, there is K-250 (trade name, manufactured by Asahi Mineseki Co., Ltd.). The content of the aggregate (B) is 40 to 65% by weight based on the entire jet black water-based coating material composition. If it is less than 40% by weight, the design property (unevenness of the coating material) is insufficient, and if it exceeds 65% by weight, the work is performed. Sex decreases.
［平均粒径１００μｍ未満の充填剤（Ｃ）］
本発明に使用する平均粒径１００μｍ未満の充填剤（Ｃ）は，塗材粘度や塗付性の調整を目的として配合し、重質炭酸カルシウム、クレー、カオリン、タルク、沈降性硫酸バリウム、炭酸バリウム、硅砂粉等が使用できるが、重質炭酸カルシウムが安価でコスト的負担を軽減させることが出来る。充填材（Ｃ）の配合量は塗材組成物全体に対して３〜２０重量％、好ましくは５〜１２重量％であり、３重量％未満では下地の色が透けるなどの隠蔽性が不足し、２０重量％超では塗材粘度が高くなって塗付作業性が不良となる。３重量％未満では色調によっては隠蔽性が低下する場合があり、１２重量％超では冬季等の低温度下では塗付作業性が低下する傾向にある。
[Filler (C) having an average particle size of less than 100 μm]
The filler (C) having an average particle diameter of less than 100 μm used in the present invention is blended for the purpose of adjusting the viscosity of the coating material and the coatability, and is made of ground calcium carbonate, clay, kaolin, talc, precipitated barium sulfate, carbonate. Barium, silica powder, etc. can be used, but heavy calcium carbonate is inexpensive and can reduce the cost burden. The amount of the filler (C) compounded is 3 to 20% by weight, preferably 5 to 12% by weight, based on the entire coating material composition. If it exceeds 20% by weight, the viscosity of the coating material increases and the coating workability becomes poor. If it is less than 3% by weight, the hiding property may decrease depending on the color tone, and if it exceeds 12% by weight, the coating workability tends to decrease at low temperatures such as in winter.
