摘要： A printable material which includes a first, second, and third layer. The first layer has first and second surfaces. For example, the first layer may be a film or a cellulosic nonwoven web. The second layer overlays the first surface of the first layer. The second layer is composed of a first thermoplastic polymer having a melt flow rate of at least about 15 g/10 minutes at a temperature of 190.degree. C. and a load of 2.16 kg. The third layer overlays the second layer. The third layer includes a second thermoplastic polymer having a glass transition temperature equal to or greater than about 30.degree. C. The third layer also may include from about 1 to about 40 parts by weight, per 100 parts by weight of the second thermoplastic polymer, of a release agent. Desirably, the first and second layers will have smoothness values, as measured by a Sheffield Smoothness Tester, no greater than about 150 cc/minute and no greater than about 100 cc/minute, respectively. The third layer may contain up to about 150 parts by weight, per 100 parts by weight of the second thermoplastic polymer, of a plasticizer, and up to about 100 parts by weight, per 100 parts by weight of the second thermoplastic polymer, of a polymeric adhesion-transfer aid. The printable material is especially suitable for use as a dye diffusion thermal transfer printable heat transfer material.
摘要翻译：包括第一层，第二层和第三层的可印刷材料。第一层具有第一和第二表面。例如，第一层可以是膜或纤维素非织造纤维网。第二层覆盖第一层的第一表面。第二层由在190℃的温度和2.16kg的载荷下的熔体流动速率为至少约15g / 10分钟的第一热塑性聚合物组成。第三层覆盖第二层。第三层包括玻璃化转变温度等于或大于约30℃的第二热塑性聚合物。第三层还可以包含每100重量份第二热塑性聚合物约1至约40重量份，的脱模剂。理想地，第一层和第二层将具有由谢菲尔德平滑度测试仪测量的平滑度值，分别不大于约150cc /分钟且不大于约100cc /分钟。相对于每100重量份的第二热塑性聚合物，第三层可以含有至多约150重量份，相对于每100重量份的第二热塑性聚合物，增塑剂，和至多约100重量份，聚合物粘合转移助剂。可印刷材料特别适合用作染料扩散热转印可印刷热转印材料。
