Photosensitive ceramic compositions containing polycarbonate polymers

摘要

The invention is directed to polymer comprising the repeat unit wherein each of R<1> through R<7> are independently hydrogen or alkyl, and R<8> is hydrogen or methyl. The invention is further directed to a photosensitive composition comprising an admixture of: (a) finely divided particles if inorganic solids selected from the group consisting of ceramic, metal, metal oxide or metal alloy; (b) finely divided particles of an inorganic binder having a glass transition temperature in the range of form 550 to 825 DEG C a surface area to weight ratio of no greater than 10 m<2>/g and at least 95 wt. % of the particles having a size of 1-10 mu m, dispersed in an organic vehicle comprising; (c) polymer as recited herein above; (d) photoinitiation system; (e) organic medium. With removal of the organic medium the above composition can be utilized for a tape. Also, in the given composition the polymer as recited above may be replaced by the polycarbonate resulting from the polymerization of 5-carbomethoxy-5-methyl-1, 3-dioxin-2-one.
