Abstract
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.
