Abstract:
A photocurable composition developable with an aqueous alkaline solution, comprising in combination:(A) an alkali-soluble macromolecular binder having a weight-average molecular weight in the range of 5,000 to 100,000 and an acid value in the range of 50 to 150 mg KOH/g and obtained by causing (c) an organic acid possessing one carboxyl group and no ethylenically unsaturated bond in its molecule to react with the glycidyl group of a copolymer of (a) a compound possessing an ethylenically unsaturated bond and possessing neither hydroxyl group nor acidic group and (b) glycidyl (meth)acrylate and then causing (d) a polybasic acid anhydride to react with the resultant secondary hydroxyl group,(B) an inorganic powder,(C) a photopolymerizable monomer,(D) a photopolymerization initiator, and(E) an organic solvent.
