Abstract
Abstract A curable resin composition comprising a cured matrix-forming component and an ultraviolet absorber, characterized in that said ultraviolet absorber comprises a benzophenone derivative represented by the formula: <IMAGE> where each of X and X' is a hydrogen atom or a hydroxyl group, provided that at least one of X and X' is a hydroxyl group, each of Y and Y' is a hydrogen, a hydroxyl group, -OROH or -OR', provided that at least one of Y and Y' is -OROH, where R is an alkylene group and R' is a monovalent organic group, and said cured matrix-forming component is reactive with a hydroxyl group.
