<p>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.</p> |
