Abstract:
1. An absorbing spin-on-glass composition comprising at least one siloxane polymer and an incorporatable organic absorbing compound that strongly absorbs light over at least an approximately 10 nm wide wavelength range, the range at wavelengths less than about 375 nm, and wherein the organic absorbing compound comprises at least one amine group, at least one carboxylic acid group, at least one branched alcohol group, at least one ketone group or at least one substituted silyl group comprising at least one silicon atom and at least one leaving group; and wherein the at least one siloxane polymer comprises hydrogensiloxane, hydrogensilsesquioxane, organohydridosiloxane, and organhydridosilsesquioxane polymers; and copolymers of hydrogensilsesquioxane and an alkoxyhydridosiloxane or hydroxyhydridosiloxane.
