Abstract
A photosensitive resin composition for photoresist which is highly sensitive and can directly form an image using a laser is disclosed. Said composition comprises (A) an unsaturated resin having carboxyl group(s) which is obtained by firstly reacting 0.8 to 1.3 moles of an ethylenic unsaturated monocarboxylic acid with 1 mole of an epoxy group of a homopolymer or copolymer of ethylenic unsaturated monomer having an epoxy group to obtain an unsaturated resin which is then reacted with a dibasic acid anhydride, (B) ethylenic unsaturated compound without epoxy group, and (C) photopolymerization initiator.
