Abstract

A polymerizable composite composition comprising a) a hydrolysate and/or condensate of at least one hydrolysable alkylsilane having at least one alkyl group, at least one hydrolysable arylsilane having at least one aryl group or at least one hydrolysable alkylarylsilane having at least one alkylaryl group, and at least one hydrolysable silane containing an epoxy group, b) at least one organic compound having at least 2 epoxy groups, and c) a cationic initiator, is suitable to provide, upon curing, substrates with a patterned coating or patterned molded articles. The patterned coatings and molded articles obtained show high relaxation ability, high chemical resistance and mechanical stability. Micropatterns can be obtained with high stability of shape.
