More Information
Summary:A photosensitive composition capable of forming pixels having good edge shapes, that is, a photosensitive composition comprising a binder resin (A) obtained by reacting a product of reaction of an epoxy resin (a) with an unsaturated carboxylic acid (b) with a polybasic carboxylic acid or an anhydride thereof (c) and a photopolymerization initiator (B), characterized in that the epoxy resin (a) is one obtained by reacting a product of polyaddition of a cyclic hydrocarbon compound having two or more unsaturated groups per molecule with a phenol with an epihalohydrin. La présente invention a trait à une composition photosensible capable de former des pixels présentant de bonnes formes de contour, c'est à dire, une composition photosensible comportant une résine liante (A) obtenue par la réaction d'un produit réactionnel d'une résine époxyde (a) avec un acide carboxylique insaturé (b) avec un acide carboxylique polybasique ou un anhydride de celui-ci (c) et un photoamorceur (B). L'invention se caractérise en ce que la résine époxyde (a) est une résine obtenue par la réaction d'un produit de polyaddition d'un composé cyclique hydrocarboné ayant au moins deux groupes insaturés par molécule avec un phénol avec une épihalohydrine.
