Flexible photosensitive polymer composition with azide and/or amine compound, poly(amic acid) and highly polar compound with boiling point above 150° C.

Claim 1

A photosensitive polymer composition comprising an admixture of: (A) 100 parts by weight of a poly(amic acid), (B) a compound or a mixture of compounds which is photosensitive and which can form a compound having two or more amino groups by irradiation with light selected from the group consisting of (i) a mixture of at least one bisazide in an amount of 0.1 to 100 parts by weight and at least one amine having at least one group of the formula: >C=C< in an amount of 1 to 400 parts by weight and (ii) 1 to 100 parts by weight of at least one amine compound having an aromatic azido group or an aromatic sulfonylazido group, and (C) 1 to 50 parts by weight of at least one compound with high polarity, having a boiling point of 150° C. or higher under atmospheric pressure and not reacting with any other component of the composition, and being selected from the group consisting of compounds of the formula: ##STR20## R b and R c are independently hydrogen, a lower alkyl group or an acetyl group; and m is an integer of 1 to 10, and compounds of the formula: ##STR21## wherein R b and R c are as defined above.
