Abstract: A heat-transfer label that is well-suited for use on untreated polyethylene, particularly untreated high-density polyethylene and untreated low-density polyethylene. In one embodiment, the label includes a support portion, the support portion comprising a paper carrier web. The label also includes a wax release layer overcoating the paper carrier web. The label further comprises a transfer portion printed on top of the wax release layer, the transfer portion including a protective lacquer layer, an ink layer and an adhesive layer. The protective lacquer layer is printed onto the wax release layer and comprises a polyester resin, castor oil and a chlorinated polypropylene capable of immobilizing the ink layer relative to the protective lacquer. The ink layer, which comprises an acrylic ink, is printed onto the protective lacquer layer. The adhesive layer is printed over the ink layer and comprises a polyamide resin, an ethylene vinyl acetate resin, erucamide and a chlorinated polyethylene resin.

Abstract: A heat-transfer label that is particularly well-suited for decorating treated low-density polyethylene (LDPE) containers and that exhibits strong resistance to degradation from animal fats and the like, even when subjected to flexing. In a preferred embodiment, the label includes a support, a wax release layer over the support and a transfer portion over the wax release layer. The transfer portion includes a protective lacquer layer, the protective lacquer layer comprising a pair of cross-linked polyester resins and a cross-linked vinyl resin, each of said cross-linked resins being cross-linked by a hexamethoxymethylmelamine resin. The transfer portion also includes an ink layer over the protective lacquer layer, the ink layer comprising a polyamide ink. The transfer portion further includes an adhesive layer over the ink layer, the adhesive layer comprising nitrocellulose and a soft polyamide resin.

Abstract: A method for decorating and/or labelling glass articles and like ceramic ware by screen printing. The present method comprises the steps of (a) treating a glass article or the like with a silane adhesion promoter; and (b) applying a non-ceramic screen ink directly onto the silane-treated glass article by screen printing. The non-ceramic screen ink is preferably a heat-set ink which includes an organic resinous binder, a non-heavy metal colorant and a vaporizable solvent system. Examples of the binder include, but are not limited to, one or more of polyamide, polyester, polyester-vinyl, acrylic, vinyl and acrylic-vinyl resins. Examples of the non-heavy metal colorant include titanium dioxide and organic colorants (e.g., insoluble derivatives of organic dyes). The non-ceramic screen ink may additionally comprise one or more rheology-adjusting agents for making the ink well-suited for screen printing and may additionally include other additives of the type commonly found in screen or other printing inks.

Abstract: A heat-transfer label particularly well-suited for styrene-acrylonitrile surfaces and containers. In one embodiment, the label includes a support portion, a skim coat of wax on top of the support portion, and a transfer portion on top of the skim coat of wax. The support portion includes a sheet of paper overcoated with a release layer of polyethylene. The transfer portion includes an acrylic protective lacquer layer, an ink layer over the protective lacquer layer, and a heat-activatable adhesive layer over the ink layer. The protective lacquer layer includes a methyl/n-butyl methacrylate copolymer and a methyl methacrylate copolymer. The ink layer includes a polyamide and/or acrylic ink. The adhesive layer includes an acrylic resin and a chlorinated polyolefin resin.
