Patent ID: 6875487

Claim:
A heat-setting label sheet, which comprises: (i) a support; (ii) a pressure sensitive adhesive layer on said support, said pressure sensitive adhesive layer comprising at least one material selected from the group consisting of: (a) a polyester having a glass transition temperature (Tg) of less than 0° C., (b) an acrylic polymer having a glass transition temperature (Tg) of less than 0° C., and (c) a copolymer blend having a glass transition temperature (Tg) of less than 0° C.; (iii) an Adhesion Layer on said pressure sensitive adhesive layer, said Adhesion Layer comprising at least one material selected from the group consisting of a thermoplastic polymer which melts in the range of 50-250° C., a wax which melts in the range of 50-250° C., and combinations thereof, wherein the Adhesion Layer is capable of being removed from the support without heat; (iv) a first optional opaque layer on said Adhesion Layer; (v) a second optional opaque layer on said first optional opaque layer (iv), or on said Adhesion Layer; and (vi) an image receiving layer on said Adhesion Layer, or on said first and/or second optional opaque layers, when present.
