Abstract
Disclosed are a photosensitive composition which is developable with an aqueous alkaline solution and such calcined patterns as a conductor pattern, a vitreous dielectric pattern, and a fluorescent pattern which are obtained by the use of the photosensitive composition. The photosensitive composition comprises (A) a carboxyl group-containing polymer obtained by the reaction of (a) a hydroxyl group-containing polymer with (b) a polybasic acid anhydride and/or (F) a carboxyl group-containing photosensitive polymer obtained by causing the carboxyl group-containing polymer (A) mentioned above to react further with a compound containing a glycidyl group and an unsaturated double bond, (B) a diluent, (C) a photopolymerization initiator, and (D) an inorganic powder. The composition may be in the form of paste or in the form of a dry film. When the photosensitive composition is in the form of paste, the paste is applied to a substrate and then dried to form a film. When the photosensitive composition is in the form of a dry film, the film is laminated on the substrate. A calcined pattern of high fineness is obtained by patterning the superposed layer of the composition by selective exposure to light and development, and thereafter calcining the patterned film.
