Abstract
Abstract A photosensitive polyimide polymer composition comprising a solvent soluble polyimide condensation product of an aromatic dianhydride and an aromatic diamine, a polyfunctional ethylenically unsaturated monomer and a photoinitiator. The solvent soluble polyimides of the composition are prepared from at least one compound selected from 2,2-hexafluoro-bis-(3,4-dicarboxyphenyl)tetracarboxylic dianhydride; 1,1-bis-[4-(1,2-dicarboxyphenyl)]-1-phenyl-2,2,2-trifluoroethane dianhydride; 2,2-hexafluoro-bis(3-aminophenyl)propane; 2,2-hexafluoro-bis(4-aminophenyl)propane; 2,2-hexafluoro-bis-[4-(3-aminophenoxy)phenyl]propane; 2,2-hexafluoro-bis-[4-(4-aminophenoxy)phenyl]propane and 1,1-bis-(4-aminopheny)-1-phenyl-2,2,2-trifluoroethane or mixtures thereof.
