ABSTRACT:
A repeatedly usable and releasable sheet is coated thereon with an adhesive copolymer microspheres-containing aqueous suspension and polymer microparticles prepared by polymerization of one or more vinyl monomers. In the presence of a protective colloid comprising casein, the microspheres is prepared by aqueous suspension polymerization of (a) from 70 to 99.9 percent by weight of one or more monomers selected from the group consisting of alkyl acrylate esters and alkyl methacrylate esters, (b) from 0.1 to 10 percent by weight of one or more .alpha.-monoolefin carboxylic acids and (c) from 0 to 29.9 percent by weight of one or more vinyl monomers other than the foregoing (a) and (b).
