Abstract:
A water-developable photosensitive resin composition comprising:(A) in the range of about 25 up to about 80 wt % of at least one copolymer comprising in the range of:(i) about 25 up to about 95 mol % of at least one elastomer forming monomer,(ii) about 0.5 up to about 30 mol % of at least one .alpha.,.beta.-ethylenically unsaturated carboxylic acid, and(iii) about 0.1 up to about 50 mol % of at least one polyfunctional vinyl monomer, provided, however, that said copolymer contains substantially no diene;(B) in the range of about 0.2 up to about 2 mol of at least one washout aid per mol of carboxyl groups in copolymer (A),(C) in the range of about 5 up to about 70 wt % of at least one ethylenically unsaturated monomer,(D) in the range of about 0.01 up to about 20 wt % of at least one photopolymerization initiator,(E) in the range of about 0 up to about 50 wt % of at least one polymer selected from the group consisting of:a linear thermoplastic, elastomeric block polymer having at least one unit of the general formula (A-B-A), (A-B).sub.n or (A-B), wherein A is a non-elastomeric polymer block having a number average molecular weight of 2,000 to 100,000 and a glass transition temperature above about 25.degree. C., and B is an elastomeric polymer block having a number average molecular weight of 25,000 to 1,000,000 and a glass transition temperature below about 10.degree. C., anda linear polymer having a molecular weight of at least 1,000, which has at least 30 mol % of a conjugated diene unit,(F) in the range of 0 up to about 20 wt % of at least one plasticizer, and(G) in the range of 0 up to about 20 wt % of at least one emulsifier.
