Title:
WATER-BASE PHOTOSENSITIVE RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/1996/030452
Kind Code:
A1
Abstract:
A water-base photosensitive resin composition which has satisfactory resist properties equal or superior to those of solvent-base photosensitive resin compositions currently in commercial use and is developable with a dilute aqueous alkali solution. The composition comprises as the essential components: (a) an aqueous emulsion of a polymeric compound containing carboxyl groups; (b) a compound having a photopolymerizable ethylenically unsaturated bond; (c) a photopolymerization initiator capable of generating free radicals upon exposure to actinic light; and (d) an adhesion accelerator; the component (a) having a weight average molecular weight in the range of from 1,000 to 50,000, an acid value in the range of from more than 140 to 250 mg-KOH/g, and a glass transition temperature in the range of from 50 to 200 �C.
