A curable resin composition capable of forming an overcoat for optical devices efficient in smoothening the uneven surface of a color filter formed on a substrate, which satisfies the requirements of transparency, heat resistance, surface hardness, and tight adhesion and which exhibits excellent load resistance even under heating and little produces sublimates in baking; overcoats made from the composition; and a process for formation of the overcoats. A curable resin composition comprising (A) a polymer having two or more epoxy groups and an Mw/Mn ratio of 1.7 or below wherein Mw and Mn are a weight-average molecular weight and a number-average molecular weight, respectively, as determined by gel permeation chromatography in terms of polystyrene, and (B) a cationic polymerizable compound different from the component (A). |
