ABSTRACT:
A curable composition comprising (a) a curable polyimide soluble in organic solvents and (b) a polymerization initiator as essential components, said polyimide consisting of recurring units represented by the formula ##STR1## wherein, each of X, X.sub.1, X.sub.2, X.sub.3 and X.sub.4 is a tetravalent carbocyclic or heterocyclic residue, each of Y.sub.1, Y.sub.2, and Y.sub.3 is a divalent carbocylic or heterocyclic residue, at least one of Z.sub.1 and Z.sub.2 is a residue having a reactive carbon-carbon double bond, and each of l, m, and n is an integer from 0 to 20, preferably from 0 to 10. The polyimide may include (a) polyacrylate compounds (b) bis-imide compounds (c) photosensitive polyimide precursors (d) oxime initiators (e) a 3 component sensitizer of a phenone compound, a mercapto compound, and an arylamine-alkanol, or mixtures of a,b,c,d, and e.
