ABSTRACT:
A recording element is disclosed which is capable of providing high-quality, high information-density recording by thermal deformation. The element comprises a support having thereon a layer of amorphous material. The amorphous material is capable of being thermally deformed to form depressions surrounded by sharply defined ridges when impinged upon by a high energy-density recording beam. The amorphous material comprises either a binder and a dye or a certain solvent-coatable dye, Iosol Red. The amorphous material must have an absorption factor, as herein defined, greater than 20. The depressions which are formed in the described material are such that they are readable by a reading beam which is not absorbed by the material.
