Patent ID: 7678436

Claim:
A method of making an overlaminating adhesive film, the method comprising producing an adhesive layer comprising a silicon-containing acrylic emulsion-type adhesive by a process comprising emulsion-polymerizing a monomer component, which includes an alkoxysilane group-containing unsaturated monomer in which each alkoxy group has 1 to 4 carbon atoms, but which includes no hydroxy-containing unsaturated monomer, to form an aqueous dispersion; adjusting the pH of the aqueous dispersion to a range of from 7.2 to 8.5 to obtain an aqueous emulsion comprising the silicon-containing acrylic emulsion-type adhesive, where the silicon-containing acrylic emulsion-type adhesive has an average particle size of 200 nm or smaller; providing a transparent film and a release material; applying a coating of the aqueous emulsion onto either the transparent film or the release material; and drying the coating; and laminating the transparent film, the adhesive layer and the release material to produce the overlaminating adhesive film.
