A carbon black graft polymer which excels in stability of dispersion in various media, coloring property, and imperviousness to light is obtained by mixing under heating a block- or graft-copolymer having a segment (A) containing a reactive group capable of reacting with a functional group on the surface of carbon black and a segment (B) different in skeletal structure from the segment (A) with carbon black. The carbon black graft polymer, by causing the graft chain thereof to incorporate therein an ethylenically unsaturated double bond and/or a carboxyl group, is enabled to manifest photosensitivity, developability with an alkali, and insulating property and acquire usefulness for a black photocurable resin composition such as, for example, the material for the formation of a black matrix particularly in a color filter.
一种炭黑接枝聚合物在各种介质中的分散稳定性、着色性和不透光性都很出色,它是通过在加热下混合块状或接枝共聚物而获得的,这种块状或接枝共聚物具有含有能与炭黑表面官能团反应的活性基团的区段(A)和在骨架结构上不同于炭黑区段(A)的区段(B)。这种炭黑接枝聚合物通过在其接枝链中加入乙烯不饱和双键和/或羧基,使其具有光敏性、碱显影性和绝缘性,可用于黑色光固化树脂组合物,例如用于形成黑色基体的材料,特别是用于彩色滤光片。
