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.

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 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.

Heat-transfer label

An improved release formulation for use in a heat transferable laminate wherein an ink design image is transferred from a carrier support to an article by application of heat to the carrier support. On transfer the release splits from the carrier and forms a protective coating over the transfered design. The improved release is coated onto the carrier as a solvent based-wax release. The release coating is then dried to evaporate the solvent contained therein. The improved release has the property that its constituents remain in solution down to temperatures approaching ambient temperature. Upon transfer, the release forms a protective coat which may be subjected to hot water. The improved release contains a montan wax, a rosin ester or hydrocarbon resin, a solvent, and ethylene-vinyl acetate copolymer having a low vinyl acetate content.

Heat transferable laminate

A label carrier web transport for use in heat transfer decorators and the like, in which labels are optically registered to control web transport. A timing assembly coordinates the rotation of a cam shaft with the actuation and deactuation of clutch and brake assemblies within a metering roll. An optical scanner trained on the web registers a predetermined contrast location to actuate the brake and deactuate the clutch, subject to the presence of an enabling signal from the timing assembly. The metering roll, in combination with a reciprocating label shuttle, provides intermittent web motion to achieve controlled label advance. An alternative label transport system incorporates a capstan web drive in lieu of the metering roll, with a microprocessor to control various machine functions including intermittent web transport.

Web transport system with electro-optical label detection

A compact and inexpensive decorator for transferring labels by heat and pressure from a carrier strip to articles such as bottles. The decorator is designed as a unit, including infeed and outfeed conveyors, a turret for holding articles during labelling and maintaining their shape by inflation, a deck bearing a transport for the carrier web and a device for impressing labels from the strip onto the articles, and a control module. For round articles the turret includes interchangeable Index and Decorator cups, while for oval articles an easily removed turret base with article cutouts is used. The deck may be adjusted in its height and angular orientation with respect to the turret to permit decoration of a wide variety of article faces. The carrier web transport includes a capstan web drive for pulling the web, a double gate, and a dancer roll, which provide label-by-label advance of the web controlled by signals from a photoelectric web monitor and a container detector. The double gate and dancer roll are included to avoid regions of slack or high tension in the web during intermittent advance.

Application of indicia to articles

A coder for imprinting the tops of crowns, closures or the like which includes a floating print roll which is independently fine turnable to accomodate height variations in the items being encoded, said print roll being lever supported for quick release from an ink metering roll upon being raised by the item to be imprinted. The print roll is rotatably driven by the items to be imprinted and the metering roll and inking roll of the coder are both preferably driven to relieve wear between the inking and metering rolls.
