Heat-sensitive recording materials

A heat-sensitive recording material 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, characterised in that
• the heat-sensitive recording material has a residual moisture of from 2 to 14%.

A heat-sensitive recording material 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 by local action of heat, so that the underlying colour layer becomes visible, characterised in that the heat-sensitive layer comprises from 10 to 90 wt. % of scattering polymer particles having a mean particle size in the range of from 0.1 to 2.5 μm, 10 to 80 wt. % of a heat-sensitive material having a melting temperature in the range of from 40 to 200° C. and/or a glass transition temperature in the range of from 40 to 200° C., and 1 to 30 wt. % of a binder.

A heat-sensitive recording material comprising

• a web-like support material,
• an insulation layer on one side of the web-like support material,
• a colour layer on the insulation layer 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.

A heat-sensitive recording material comprising

• a web-like support material,
• a layer which is simultaneously a colour layer and an insulation 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.

• 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,
• characterised in that the heat-sensitive layer contains or consists of a heat-sensitive material as scattering particles, the heat-sensitive material being selected from the group of biopolymers, modified biopolymers, fats, natural waxes, semi-synthetic waxes and/or synthetic waxes.
