Abstract
A positive type actinic ray-curable (dry film having, on the surface of a non-actinic ray-curable substrate, a solid positive type actinic ray-curable urethane resin layer formed from (1) a resin composition containing, as essential components, (A ) an ether linkage-containing olefinicaly unsaturated compound, (B ), an acid group-containing urethane resin having a weight average molecular weight of 1,000 to 200,000 and an acid group content in the range of 0.5 to 10 equivalents per one kg of the resin, and (C) a photo-acid generator; (2) a resin composition containing, as essential components, (A ) an ether linkage-containing, polyurethane based, olefinicaly unsaturated Compound, (B ) at least one resin selected from the group consisting of (a) a carboxyl group and hydroxyphenyl group-containing polymer, (b) a carboxyl group-containing polymer and (c) a hydroxyphenyl group-containing polymer, and (C) a photo-acid generator; or (3) a resin composition containing, as essential components, (A ) an ether linkage-containing, polyurethane based, olefinicaly unsaturated compound, (B ) an acid group-containing urethane resin having a weight average molecular weight of 1,000 to 200,000 and an acid group content in the range of 0.5 to 10 equivalents per one kg of the resin, and (C) a photo-acid generator; and a method of forming a pattern by use of the dry film.
