To obtain a thermosensible coloring paper in which the generation of bubbles in a laminate layer applied on paper is prevented by laminating the laminate layer and a thermosensible coloring layer having specified thermal diffusivity in sequence at least on one side of paper having specified thermal diffusivity.

A laminate layer is formed at least on one side of paper, and at least one thermosensible coloring layer which is colored in a prescribed color by heating is laminated on the laminate layer to form thermosensible coloring recording paper. In this case, it is necessary that the thermal diffusivity κ0 of the paper for the thermal diffusivity of the thermosensible coloring layer is a value which meets a numerical formula expressed by 0.25κ0<K<1.5κ0. Practically, in the thermosensible coloring recording paper 10, a cyan thermosensible coloring layer 12, a magenta thermosensible coloring layer 13, a yellow thermosensible coloring layer 14, and a protective layer 15 are laminated in sequence on a support 11 to form a back layer 16. In the support 11, laminate layers 21, 22 are formed on both sides of the paper 18 with polyethylene incorporated with TiO2 powder.
