TRANSPARENT PATTERN IN A WHITE MICROVOIDED POLYMERIC FILM, AND PROCESS FOR OBTAINING THE SAME

摘要

A permanent transparent pattern in a non-transparent microvoided axially stretched self-supporting polymeric film; a layer configuration comprising the permanent transparent pattern in a non-transparent microvoided axially stretched self-supporting polymeric film exclusive of foam; a non-transparent microvoided thermally transparentizable axially stretched self-supporting polymeric film; and a process for obtaining a permanent transparent pattern comprising the step of: image-wise application of heat optionally supplemented by the application of pressure to the non- transparent microvoided axially stretched self-supporting polymeric film.
