ABSTRACT:
A method is disclosed, and a corresponding thermal imaging medium for use with it, for the formation of an improved heat mode image comprising (A) exposing information-wise to laser radiation a thermal imaging medium comprising (1) a transparent support, (2) an image recording layer containing a hydrophilic binder, a substance capable of converting laser radiation into heat, and a dispersion of a hydrophobic polymer capable of undergoing thermocoagulation by the action of heat and having a built-in UV-absorber. A heat mode image with high density and improved resistance to physical damage is obtained.
