ABSTRACT:
This invention relates to an aqueous film-forming mixture which does not contain a vinyl halide and which can be utilized to prepare conformable films which are useful in various applications such as adhesive tapes, labels and decorative sheets. The aqueous film-forming mixtures generally comprise, based on the weight of the solids in the aqueous mixture, (A) from about 50% to about 80% by weight of an acrylic-urethane copolymer which forms a film having an elongation at break of at least about 300%, and (B) from about 5% to about 25% by weight of an acrylic polymer or copolymer having a Tgof less than about 55° C., wherein the acrylic polymer or copolymer (B) is different from the acrylic-urethane copolymer (A). The aqueous mixtures also may contain up to about 40% by weight of a pigment. These aqueous film-forming mixtures are useful in preparing conformable films and other articles such as adhesive articles which comprise an adhesive layer and a layer of the conformable film of this invention which is adhered to the adhesive layer. The conformable films of the present invention may be printed with various graphics, and the films are die-cuttable.
