Abstract
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.
