A coating composition for improving adhesion between glass and ethylenically unsaturated resin comprising from about 5 to 95 weight percent of a methacryloxyalkyltrialkoxysilane, and from about 5 to 95 weight percent of alkyltrialkoxysilane from about 5 to 95 weight percent of alkyltrialkoxysilane, each alkyl or alkoxy group having 1 to 3 carbon atoms.

A method for improving adhesion between glass and a polymerizate of an ethylenically unsaturated resin which comprises:

• treating glass with a solution of a silane composition, the composition comprising from about 5 to 95 weight percent of a methacryloxyalkyltrialkoxysilane and from about 5 to 95 weight percent of an alkyltrialkoxysilane, each alkyl or alkoxy group having 1 to 3 carbon atoms;
• contacting treated glass with an ethylenically unsaturated resin, and
