Pressure sensitive adhesive film overlamination

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.
