    • Processes for making a pragmatic label, a receiver sheet for making such a pragmatic label, and intermediates thereof are described. The receiver sheet comprises a pragmatic pre-label sheet, a lower strippable carrier, a pressure-sensitive adhesive layer between said lower strippable carrier and the pragmatic pre-label sheet. The pragmatic pre-label sheet is made by coextruding a first melt for a polymeric image-receiving layer with one or more other melts for forming a single-layer or multiple-layer pragmatic polymer sheet, wherein said other melts includes a second melt comprising an orientable thermoplastic polymeric material for forming a microvoided layer, said coextruded melts forming a multilayer composite film that is subsequently subjected to stretching. The pragmatic labels and receiver sheets of the present invention can advantageously be made without the use of solvent coating.
    • 描述了制作实用标签的过程,制作这样一个实用标签的接收片及其中间体。 接收片包括实用的预标签片,下可剥离载体,在所述下可剥离载体和实际预标签片之间的压敏粘合剂层。 通过用用于形成单层或多层实用聚合物片的一种或多种其它熔体共挤出用于聚合物图像接收层的第一熔体来制备实用的预标签片,其中所述其它熔体包括第二熔体,其包含 用于形成微空隙层的可取向的热塑性聚合物材料,所述共挤出的熔体形成随后进行拉伸的多层复合膜。 本发明的实用标签和接收片可以有利地在不使用溶剂涂层的情况下制成。
