RECORDING MATERIAL FOR DIRECT THERMAL IMAGE FORMING METHOD

摘要

PURPOSE: To provide a heat-sensitive recording material suited for use in direct thermal imaging by means of an information-wise energized heating element. CONSTITUTION: A heat-sensitive recording material which has at least one binder layer contg. a substantially light-insensitive metal salt in thermal working relationship with at least one org. reducing agent on the same side of a support called as the heat-sensitive side and additionally contains an acid-sensitive leuco dye and wherein the leuco dye is an acid-sensitive leuco dye transformable into a dye by means of an acid-reactive compd. serving as a dye developing main agent that stand in thermal working relationship therewith, is provided.
