    • 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 (13) and a transfer portion (21), the transfer portion being positioned over the support portion. The support portion (13) includes a sheet of paper (15) overcoated with a release layer of polyethylene (17). The transfer portion (21) includes an organic solvent-soluble phenoxy protective lacquer layer (23), an organic solvent-soluble polyester ink layer (25) over the protective lacquer layer, and an acrylic adhesive layer (27) over the ink layer. The adhesive layer (27) is formed by depositing onto the ink layer (25), 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.
    • 用于形成粘合剂层的组合物和包含这种粘合剂层的热转印标签。 在一个实施方案中,该标签设计用于经受巴氏消毒条件类型的硅烷处理的玻璃容器。 标签包括支撑部分(13)和转印部分(21),转印部分位于支撑部分上方。 支撑部分(13)包括用聚乙烯(17)的脱模层覆盖的一张纸(15)。 转印部分(21)包括有机溶剂可溶的苯氧基保护漆层(23),保护漆层上的有机溶剂可溶性聚酯油墨层(25)和在油墨层上方的丙烯酸粘合剂层(27)。 粘合剂层(27)通过沉积到油墨层(25)上而形成,例如通过凹版印刷,包含水基丙烯酸树脂分散体或乳液,异丙醇和水的组合物,然后蒸发 组合物留下丙烯酸膜。
