Abstract (en)

[origin: WO2022262908A2] The present invention relates to heat-sensitive recording materials comprising a web-like support material, a colour layer on one side of the web-like support material and a heat-sensitive layer on the colour layer, so that the colour layer is at least partially covered, the heat-sensitive layer being designed so that it becomes translucent due to local action of heat, so that the underlying colour layer becomes visible.
