Abstract
A process for the production of a recording material consisting of a layer support and one or more recording layers cast thereon, for example a magnetic layer or photographic layers, is characterized in that the flexible layer support in the form of a tape contains at least one liquid crystalline polymer. The recording material thus produced is distinguished by excellent properties and in addition affords the advantage that after production of the layer support, the recording layers can be applied on line at a high casting velocity by means of known casting processes.
