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 .
