Two-color recording type thermal recording sheet

Abstract

Abstract PURPOSE:To enable to develop two arbitrary colors and a mixed color of the two color, by providing a thermal recording layer comprising a diazo compound and a coupling agent on both sides of a transparent base. CONSTITUTION:The thermal recording layer 2 is provided on the upper side of the transparent base 1 of the thermal recording sheet A, and the thermal recording layer 3 is provided on the lower side of the base 1. The base 1 is transparent so that an image recorded in one of the thermal recording layers can be seen therethrough from the side of the other thermal recording layer. Each of the recording layers 2, 3 comprises a diazo compound and a coupling agent as main constituents in a binder. Since thermal recording is performed from above an adhesive layer 4 in using the thermal recording sheet A, it is preferable that the adhesive layer 4 further includes a lubricant and a releasing agent.
