A heat-transfer label well-suited for use in decorating silane-treated glass articles. In a preferred embodiment, the label exhibits good scuff resistance, is capable of withstanding pasteurization conditions on a silane-treated glass article and 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 cross-linked phenoxy protective lacquer layer printed onto the skim coat, a polyester 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 cross-linked phenoxy resin comprises a solvent-soluble phenoxy resin of the formula [ STR 1 ] wherein the solvent-soluble phenoxy resin is cross-linked by a melamine formaldehyde resin. The adhesive layer comprises a phenoxy resin of the type present in a water-based phenoxy resin dispersion. The adhesive layer is preferably made by gravure printing onto its underlying layers an adhesive composition comprising the water-based phenoxy resin dispersion, isopropyl alcohol and water, and then evaporating the volatile components of the composition to leave an adhesive phenoxy film.
