Title: ALKALI DEVELOPMENT TYPE PHOTOCURABLE COMPOSITION AND PATTERN OF BURNED MATTER OBTAINED FROM THE SAME
Abstract:
An alkali development type photocurable composition which comprises: (A) an alkali-soluble polymeric binder which is obtained by reacting (d) a compound having one glycidyl group per molecule with the carboxyl groups of either a copolymer of (a) a compound having an ethylenically unsaturated bond and having one carboxyl group per molecule and (b) a compound having an ethylenically unsaturated bond and having neither a hydroxyl group nor an acid group or a copolymer of the compounds (a) and (b) and (c) a compound having an ethylenically unsaturated bond and a hydroxyl group to yield hydroxyl groups and reacting the resultant hydroxyl groups with (e) a polybasic acid anhydride and which has a weight-average molecular weight of 5,000 to 100,000 and an acid value of 50 to 150 mg/KOH; (B) inorganic particles; (C) a photopolymerizable monomer; (D) a photopolymerization initiator, and (E) an organic solvent. This composition has excellent storage stability. By using this composition, a highly precise and fine pattern of a burned matter, such as a conductive or dielectric pattern, can be easily formed by photolithography.
