Abstract
A heat-transfer label including a non-wax, non-silicone release layer for use in decorating an article without leaving a visually discernible release residue on the decorated article. In a preferred embodiment, the label includes a transfer portion comprising a protective lacquer layer, an ink design layer over the protective lacquer layer, and a heat-activatable adhesive layer over the ink design and protective lacquer layers, the adhesive layer extending beyond the peripheries of the ink design and protective lacquer layers. The adhesive layer preferably includes a polyester resin and an anti-blocking agent, such as a paraffinic wax. The label also includes a support portion, the support portion including a carrier and a non-wax, non-silicone release layer positioned over the carrier and in direct contact with the protective lacquer layer and the periphery of the adhesive layer.
