Title:
POLYMER COMPLEX AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JP2888269
Kind Code:
B2
Abstract:
PURPOSE: To obtain a polymer complex excellent in low stress and having a new sea-island structure and to supply a low stress insulation film using the complex.
CONSTITUTION: This polymer complex of a sea-island structure especially, the insulating film comprises a polyimide resin consisting essentially of a tetracarboxylic acid dianhydride, an aromatic and a curable resin. A solvent is removed from a mixed solution of a polyamic acid and an uncured curable resin (acrylic or phosphazene-based curable resin) under a proper condition to give a sea-island structure. The curable resin is cured by light exposure, etc., optionally developed and then the polyamic acid is subjected to ring closure through dehydration.
