Photosensitive coating compositions, thermally stable coatings prepared from them, and the use of such coatings in forming thermally stable polymer images

摘要

This invention is concerned with the formation of thermally stable positive and negative images on substrate surfaces, the images being capable of withstanding heating to at least 200°C without significant loss in image quality or resolution. The images are formed from a dual acting, aqueous developable, crosslinkable polymer coating which is itself formed from a thermally stable, photosensitive coating composition comprising acid hardening resin system and photoacid generator dissolved in solvent. The coating compositions may also be used to form protective coatings and planarizing layers on substrate surfaces.
