Beschreibung
Zusammenfassung:	PURPOSE:To impart stability without degrading coating film performance by compounding pigments, an ethylenic unsaturated copolymer which has alkoxysilane groups at side chains and of which the number average mol.wt. is within a specific range, and an organic dispersion medium. CONSTITUTION:A pigment dispersed liquid prepd. from pigments, an ethylenic unsaturated copolymer which has at least one alkoxysilane groups at side chains and of which the number average mol.wt. is 1,000-100,000 and an organic dispersion medium. Said ethylenic unsaturated copolymer is obtained by the radical copolymer reaction of an alkoxysilane-group-contg. unsaturated monomer such as gamma-methacryloxy propyl trimethoxysilane and an ethylenic unsaturated monomer such as styrene or alpha-methyl styrene. Inorg. pigments such as carbon black, org. pigments such as natural dye-base and nitroso-base pigments, etc. may be used for the pigments.
