Abstract
General purpose permanent, environmentally benign, pressure-sensitive adhesives and self-adhesive postage stamps and other laminate constructions are provided. In one embodiment, the PSA is an inherently, acrylic copolymer prepared by emulsion polymerization of 27 to 29% di-(2-ethylhexyl) maleate, 19 to 21% vinyl acetate, 40 to 43% ethylhexyl acrylate, 5 to 10% methyl methacrylate, 1% acrylic acid, and 1% methacrylic acid. Notably, no multifunctional monomers having a cyanurate or phosphate moiety are included in the polymer, and the polymer is substantially uncrosslinked.
