摘要:
A heat-sensitive image recording material contains on a support material 1. at least one binder layer with a heat-sensitive imaging combination of an organic silver salt and an organic reducing agent for the organic silver salt, and 2. at least one binder layer or a sequence of binder layers with a heat-sensitive imaging combination of an acid-sensitive leuco dye and an acidically reacting compound which acts as a developer for the leuco dye, wherein the leuco dye and developer are in thermal interaction with each other either in different layers or separately from each other in the same layer, characterised in that a layer with a water- or alcohol-soluble polymer is arranged between the combination of organic silver salt and organic reducing agent for the organic silver salt, on the one hand, and the combination of leuco dye and acidically reacting compound, on the other. The image recording material is suitable for recording thermal images with elevated optical density, good grey scale reproduction and good stability.
