Abstract:
In an aqueous emulsion based pressure sensitive adhesive, capable of bonding to a substrate on instantaneous contact, comprised of a copolymer having polymerized units of C.sub.1-12 esters of acrylic or methacrylic acid, the improvement residing in the properties of the pressure sensitive adhesive which comprises a copolymer having a glass transition temperature of from -25 to -50.degree. C. and consisting of polymerized units of the following monomers:(a) 5-40 wt % of a vinyl C.sub.8-13 ester of a neo-acid obtained from a feedstock of propylene oligomer;(b) 30-80 wt % of a mixture of methyl methacrylate and at least one other monomer selected from the group consisting of 2-ethylhexyl acrylate and butyl acrylate; and(c) an alpha, beta-ethylenically unsaturated monocarboxylic acid in an amount from 2% up to 10 wt %.
