Abstract
A heat-sensitive recording material suitable for offset printing, having a web-shaped substrate, having a front side and a reverse side opposite the front side, a heat-sensitive recording layer disposed at least on one of the two sides of the web-shaped substrate having at least one dye precursor and at least one (color) developer reactive with the dye precursor. The heat-sensitive recording layer has particles including an organic surface whose extent in the direction of the thickness of web-shaped substrate and heat-sensitive recording layer is greater than the thickness of the heat-sensitive recording layer.

A heat-sensitive recording material configure for offset printing, comprising:
- a web-shaped substrate, having a front side and a reverse side opposite the front side;
- and
- a heat-sensitive recording layer disposed at least on one of the two sides of the web-shaped substrate, comprising:
- at least one dye precursor;
- at least one (color) developer reactive with the at least one dye precursor;
- and
- particles having an organic surface whose extent in a direction of a thickness of the web-shaped substrate and the heat-sensitive recording layer is greater than a thickness of the heat-sensitive recording layer,
- wherein the particles are selected from the group consisting of:
