Abstract (en)

[origin: WO9914056A1] The present invention relates to a thermo-sensitive printing sheet having a thermo-sensitive printing layer that contains chromogenic substances as well as chromo-acceptors. The surface opposed to the printing layer comprises a back coating of a mixture containing the following elements: starch, an acrylate copolymer which is free from styrene or vinylacetate components and has a film-forming temperature lower than 5 DEG C, and an alkaline catalyst.
