Abstract
A curable composition including (A) a compound which has a plurality of ethylenically unsaturated double bonds and secondary hydroxyl groups, (B) a photopolymerization initiator, and (C) a coloring agent, is used to provide a curable composition which exhibits excellent storage stability such as dispersion stability even in the case where a coloring agent is included at high concentration, highly sensitive curability by exposure, high adhesiveness to the surface of a hardening material in a curing region when applied in forming patterns on the surface of the hardening material, excellent uncured region removability, and excellent pattern formability; a color filter having colored patterns, which is formed by using the curable composition and has excellent resolution and adhesiveness to the support; and a manufacturing method of the coloring filter with high productivity.
