Photosensitive polyimide composition

PURPOSE: To attain thermal stabilization by using a specified bis-(3-amino-4- hydroxyphenyl) compd., a diacid anhydride such as specified bis-(3,4- dicarboxyphenyl) anhydride or aliphatic tetracarboxylic acid anhydride and a photoactive compd. CONSTITUTION: This photosensitive polyimide compsn. consists of bis-(3-amino-4- hydroxyphenyl) compd. represented by formula I, a diacid anhydride such as bis-(3,4-dicarboxyphenyl) anhydride represented by formula II or aliphatic tetracarboxylic acid anhydride and a photoactive compd. such as bisazide. In the formula I, Q is -O-, -S-, etc. In the formula II, Z is -O-, -S-, -O-Ar-S-Ar-O, etc. Thermal stabilization is attained. COPYRIGHT: (C)1991,JPO
