ABSTRACT:
An aqueous composition for forming a release coating layer on a substrate, comprising 100 parts by weight (solids basis) of a mixture of aqueous components of polysiloxanes and from about 20 to 100 parts by weight (solids basis) of an aqueous resin having film-forming ability, wherein the non-volatile content is from about 1 to 60% by weight. The aqueous composition is applied onto a non-permeable substrate to provide a substrate having thereon a release coating layer, which is suitable for use in the production, for example, of a surface protective sheet or tape, and a pressure-sensitive sheet or tape.
