ABSTRACT:
A heat mode element with improved mechanical properties is disclosed comprising a transparent support, a thin metallic recording layer, an adhesive layer, a polymeric resin layer and a top layer comprising a roughening agent in such an amount that the R.sub.a value of said top layer is at least 0.08 .mu.m and the R.sub.z value is at least 0.6 .mu.m. In a preferred embodiment the metallic recording layer is a bismuth layer, and the support has on the other side a backing layer with a low R.sub.a and R.sub.z value.
In an alternative embodiment the top layer is absent and the roughening agent is incorporated in the polymeric resin layer itself.
Also disclosed is a method for obtaining a heat mode image by the information-wise laser exposure of the disclosed element.
