沢と淡色濃度に大きく関与し、より高いものが好まれて
いる。Conventionally, various black paints have been used in various fields such as automobiles, construction materials, furniture, and electronics. Carbon black is mainly used as the black pigment, and thermosetting resin as a binder, such as melamine alkyd resin, epoxy resin, polyurethane resin, etc.
A thermoplastic resin, such as nitrocellulose or a polyvinyl compound, is diluted and mixed with an organic solvent or water, applied, and dried or cured with heat or air to form a paint film. One of the important properties of paints is dispersibility, and in practical terms, it greatly affects gloss and light color density, and the higher the dispersibility, the better.
近年、高級指向になるにつれて、硬化後の塗料皮膜の光
沢の向上は高級感をまた白塗料を混合した場合の淡色濃

ボンブラックにその解決の要素があるとしてカーボンブ
ラックの改質が要求されている。In recent years, as people have become more luxury-oriented, the improved gloss of the cured paint film gives a sense of luxury, and the high concentration of light color when mixed with white paint is also a measure of the good dispersion stability of that paint. Since the density of light colors can be increased with a small amount of black paint, which also leads to lower costs, there is a demand for modification of carbon black, which is a black pigment, and is believed to be a solution to this problem.
本発明者等は、このような課題を解決すべく鋭意検討し

で、黒色顔料としてこのようなカーボンブラックの配合
によって優れた光沢と淡色濃度を有する黒色塗料を提供
することを目的としている。The inventors of the present invention conducted extensive studies to solve these problems, and found that these problems could be improved by impregnating carbon black with a trace amount of an amine compound. The present invention was made based on such knowledge, and an object of the present invention is to provide a black paint having excellent gloss and light color density by incorporating such carbon black as a black pigment.
そして、かかる目的は、黒色顔料及び樹脂バインダーか
らなる黒色顔料組成物において黒色顔料としてアミン化

達成される。This object is achieved by using carbon black impregnated with an amine compound as the black pigment in a black pigment composition comprising a black pigment and a resin binder.
以下、本発明の詳細な説明する。The present invention will be explained in detail below.
本発明の黒色塗料組成物で用いる黒色顔料としては、通
常の塗料用途に用いるカーボンブラックが用いられる。As the black pigment used in the black paint composition of the present invention, carbon black used in ordinary paint applications is used.
具体的には粒子径は１０〜１００ｍμ、ＤＢＰ吸油量は
２０〜３５０ｍｊ！／ １００ｇの範囲にあるカーボン
ブラックが挙げられる。Specifically, the particle size is 10 to 100 mμ, and the DBP oil absorption is 20 to 350 mJ! /100g of carbon black.
かかるカーボンブラックに対するアくン化合物の添着量
はカーボンブラックに対して通常０．０１〜１０．０重
量％、好適には０．０５〜５．０重量％が使用できる。The amount of the Akun compound impregnated to the carbon black is usually 0.01 to 10.0% by weight, preferably 0.05 to 5.0% by weight.
添着量は０．０１重量％未満であると顕著な効果が得ら
れず、また１０．０重量％を超えると添着量の割合に比
べて効果得られない。If the impregnated amount is less than 0.01% by weight, no significant effect will be obtained, and if it exceeds 10.0% by weight, no effect will be obtained compared to the ratio of the impregnated amount.
アミン化合物としては直鎖系炭化水素及び側鎖系炭化水
素で炭素原子数は４以下のアミン化合物が挙げられ、具
体的には１・４ジアミノブタン、１・３ジアミノプロパ
ン、１・２ジアミノプロパン、エチレンジアミン等が好
適に使用される。Examples of amine compounds include linear hydrocarbons and side chain hydrocarbons having 4 or less carbon atoms, specifically 1,4 diaminobutane, 1,3 diaminopropane, 1,2 diaminopropane. , ethylenediamine, etc. are preferably used.
黒色顔料はバインダー樹脂を溶剤で溶解したワニスにカ

機の種類、使用するカーボンブラックの種類あるいは塗
料ワニスにより異なるが、−船釣に塗料中にカーボンブ
ラックが１〜１０％、樹脂成分が３０〜６０％の範囲、
残りは溶剤である。Black pigment is obtained by blending carbon black with varnish in which binder resin is dissolved in a solvent. Binder resins include melamine, melamine alkyd, acrylic, urethane, nitrocellulose, etc., and the blending ratio of these can be determined by the dispersion machine. Although it differs depending on the type of carbon black used or the paint varnish, - for boat fishing, the paint contains 1 to 10% carbon black and 30 to 60% resin component;
The remainder is solvent.
一方、淡色塗料は通常、黒色顔料を配合した塗料を適当
量取り、チタン等の白色顔料を予め分散した白色塗料に
混合して作られる。配合量は所望する灰色の濃度が得ら

の高いものほど好まれる。On the other hand, light-colored paints are usually made by taking an appropriate amount of a paint containing a black pigment and mixing it with a white paint in which a white pigment such as titanium has been dispersed in advance. The blending amount is adjusted to obtain the desired gray density, but the higher the light color density of carbon black, the smaller the amount of black paint used, and therefore, the higher the light color density is preferred.
