Abstract
A photocurable resin composition comprising a photopolymerizable photosensitizing compound (A) together with or without a photopolymerizable photosensitizing compound (B), the compound (A) being prepared by esterifying with acrylic or methacrylic acid or the like a resin having an OH equivalent of 150 - 500 produced by esterification of a dialkylaminobenzoic acid, a polybasic acid or, if desired, a fatty acid having at least 9 carbon atoms, with a polyhydric alcohol, and the compound (B) being prepared by repeating the aforesaid process for preparing the compound (A) except that a carboxyl group-containing benzophenone derivative is substituted for the dialkylaminobenzoic acid.
