Abstract
A heat-transfer label that may be used, for example, to decorate clear glass articles in such a way as to give such articles the appearance of having been frosted. In a preferred embodiment, the label includes (a) a support portion in the form of a sheet of paper overcoated with a release layer of polyethylene, (b) a skim coat of wax overcoated onto the polyethylene release layer and (c) a transfer portion, the transfer portion including a protective lacquer layer printed onto the skim coat, an ink layer printed onto the protective lacquer layer, and an adhesive layer printed onto the ink layer, as well as onto any exposed portions of the underlying protective lacquer layer and onto a surrounding area of the skim coat. The protective lacquer layer comprises a solvent-soluble phenoxy resin that has been cross-linked by a melamine resin. The ink layer comprises a design printed with a frosted ink, the frosted ink preferably comprising a solvent-soluble phenoxy resin, a silica and a colorant. The adhesive layer comprises a phenoxy resin of the type present in a water-based phenoxy resin dispersion.
