Homogeneously cross-linked contact adhesive tape without a carrier, in particular a transfer tape

摘要

Double-sided self-adhesive tape (I) with at least one layer of photoinitiator-free acrylate hot-melt adhesive (II), in which the acrylate layer is homogeneously crosslinked, i.e. with no crosslinking gradient through the layer. An independent claim is also included for a method for the production of (I) by adding crosslinker(s) (III) to a (meth)acrylate ester-based polyacrylate copolymer melt (II), coating the mixture onto a temporary carrier material and crosslinking the coating, in which (III) is a thermal crosslinker and some of the (meth)acrylate ester contains prim. hydroxyl groups.
