A heat-transfer label () including a non-wax, non-silicone release layer or coating () for use in decorating an article, such as a glass container, without leaving a visually discernible release residue on the decorated article. In a preferred embodiment, the label includes a transfer portion (), the 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 label also includes a support portion (), the transfer portion being positioned over the support portion for transfer of the transfer portion from the support portion to an article under conditions of heat and pressure. The support portion comprising a carrier layer () and a release layer or coating.

Heat-transfer label including non-wax release coating

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.

Heat-transfer label including non-wax release layer

A heat-transfer label suitable for use in decorating polyethylene-coated glass articles. In a preferred embodiment, the label is capable of withstanding pasteurization conditions on a polyethylene-coated 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, a first adhesive layer printed onto the ink layer and onto any exposed portions of the underlying protective lacquer layer, and a second adhesive layer printed onto the first adhesive layer. The first adhesive layer preferably comprises an acrylic adhesive resin of the type present in a water-based adhesive dispersion or in a water-based adhesive emulsion and also comprises a surfactant in the form of dioctyl sodium sulfosuccinate. The second adhesive layer preferably comprises a chlorinated polyolefin of the type present in a water-based chlorinated polyolefin dispersion, such a dispersion having a pH at 25.degree. C. of 9-10 and containing 2-amino-2-methyl-1-propanol as a neutralizing amine, the water-based chlorinated polyolefin dispersion containing 20%, by weight, chlorinated polyolefin and 25%, by weight, total solids. The second adhesive layer preferably also comprises a thickener in the form of a polyurethane.

Heat-transfer label and method of decorating polyethylene-coated glass

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 ##STR1## 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.

Heat-transfer label including a phenoxy adhesive layer

A heat-transfer label including a phenoxy lacquer layer. In one embodiment, the label is designed for use on silane-treated glass containers of the type that are subjected to pasteurization conditions. The label includes a support portion and a transfer portion, the transfer portion being positioned over the support portion. The support portion includes a sheet of paper overcoated with a release layer of polyethylene. The transfer portion includes an organic solvent-soluble phenoxy protective lacquer layer, an organic solvent-soluble polyester ink layer over the protective lacquer layer, and a water-dispersible acrylic adhesive layer over the ink layer.

Heat-transfer label including phenoxy protective lacquer layer

A heat-transfer label suitable for use in decorating polyethylene-coated glass articles. In a preferred embodiment, the label is capable of withstanding pasteurization conditions on a polyethylene-coated 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, a first adhesive layer printed onto the ink layer and onto any exposed portions of the underlying protective lacquer layer, and a second adhesive layer printed onto the first adhesive layer. The cross-linked phenoxy resin comprises a phenoxy resin of the formula ##STR1## wherein phenoxy resin is cross-linked by a melamine formaldehyde resin. The first adhesive layer preferably comprises an acrylic adhesive resin of the type present in a water-based adhesive dispersion or in a water-based adhesive emulsion and also comprises a surfactant in the form of dioctyl sodium sulfosuccinate. The second adhesive layer preferably comprises a chlorinated polyolefin of the type present in a water-based chlorinated polyolefin dispersion and also comprises a thickener in the form of a polyurethane.

Heat-transfer label including cross-linked phenoxy lacquer layer

A composition for use in forming an adhesive layer and a heat-transfer label including such an adhesive layer. In one embodiment, the label is designed for use on silane-treated glass containers of the type that are subjected to pasteurization conditions. The label includes a support portion and a transfer portion, the transfer portion being positioned over the support portion. The support portion includes a sheet of paper overcoated with a release layer of polyethylene. The transfer portion includes an organic solvent-soluble phenoxy protective lacquer layer, an organic solvent-soluble polyester ink layer over the protective lacquer layer, and an acrylic adhesive layer over the ink layer. The adhesive layer is formed by depositing onto the ink layer, e.g., by gravure printing, a composition comprising a water-based acrylic resin dispersion or emulsion, isopropyl alcohol and water, and then evaporating the volatile components of the composition to leave an acrylic film.
