发明名称 Release film having a rough surface structure
摘要 Release film having at least one layer based on at least one thermoplastic polymer as matrix polymer, in which solid microparticles having a melting point which is at least 10° C. higher than that of the matrix polymer are dispersed therein and surfaces of which at least one is provided with a release layer as outer layer based on at least one cured polysiloxane.

主权项 1. A release film having a nonplanar but unembossed surface structure which is not caused by a foam structure, comprising at least one layer (s) based on at least one thermoplastic matrix polymer selected from the group consisting of olefin homopolymers or copolymers and polyamides or copolyamides and comprising distributed solid microparticles having a particle size of at least 50 μm and having a melting point at least 10° C. higher than that of the matrix polymer, and at least one of the surfaces of the release film is covered by a release layer (b) as outer layer, based on at least one cured polysiloxane.
