Abstract
Abstract Adhesive compositions having a Tg of -45° to -25° C. suitable for application to plasticized polyvinyl chloride comprising 30-70% by weight of a vinyl ester of a alkenoic acid; 10-30% by weight ethylene; 20-40% by weight of a di-2-ethylhexyl maleate or di-n-octyl maleate or the corresponding fumarate; and 1 to 10% by weight of a mono-carboxylic acid.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
156 words
Plasticized polyvinyl chloride substrates coated with a pressure sensitive adhesive composition comprising an emulsion polymer of 30-70% by weight of a vinyl ester of a alkenoic acid selected from the group consisting of vinyl formate, vinyl acetate, vinyl propionate, vinyl butyrate, vinyl isobutyrate, vinyl valerate, vinyl-2-ethyl-hexanoate, vinyl isooctanoate, vinyl nonate, vinyl decanoate, vinyl pivalate, and vinyl versitate; 10-30% by weight ethylene; 20-40% by weight of a di-2-ethylhexyl maleate or the corresponding fumarate; 1 to 10% by weight of a mono-carboxylic acid selected from the group consisting of acrylic acid, methacrylic acid, monoethyl maleate, monobutyl maleate and monooctyl maleate; and 0-5% of a copolymerizable comonomer selected from the group consisting of acrylamide, allyl carbamate, N-methylol (meth)-acrylamide, N-vinylpyrrolidinone, diallyl adipate, triallyl cyanurate, butanediol diacrylate, allyl methacrylic, hydroxyethyl acrylate, hydroxy propyl acrylate and the corresponding methacrylates wherein the amount of the comonomer is such as to maintain the adhesive within a T g range of -45° to -25° C.
