PROBLEM TO BE SOLVED: To improve shelf stability and resist characteristics such as sensitivity and resolving power, to reduce curing temp. and to improve physical characteristics of a film by incorporating a specified polyamic acid compd., a photosensitive auxiliary having a photopolymerizable functional group, a photopolymn. initiator and a solvent. SOLUTION: This compsn. contains at least one of polyamic acid compds. represented by formulae I, II a photosensitive auxiliary having a photopolymerizable functional group, a photopolymn. initiator and a solvent. In the formula I, R<1> is a tetravalent org. group, R<2> is a divalent org. group, 1-100% of R<2> 's are divalent org. groups represented by formula III, (k) is an integer of 5-10,000 and Z<1> is an actinic ray functional group represented by formula IV. In the formula II, R<1> is a tetravalent org. group, R<2> is a divalent org. group, 1-100% of R<2> 's are divalent org. groups represented by formula III, (k) is an integer of 5-10,000 and Z<2> is an actinic ray functional group represented by formula V. |
