PURPOSE:To obtain recording paper having both properties of a thermal copy characteristic and a pressure-sensitive copy characteristic and reduced in contamination due to carbon ink, by constituting said recording paper of upper paper wherein a layer containing a colorless electron donating color forming org. compound (a color forming substrate) and an org substance (coupler) allowing said compound to form a color at the time of heating is provided on the front surface of a base sheet and a layer containing the colorless color forming substrate, the microencapsulated colorless color forming substrate and a heat-meltable substance is provided to the back surface thereof and lower paper wherein a layer containing one or more of the coupler is provided on the front surface of a base sheet. CONSTITUTION:Pressure-sensitive thermal multilayered copy paper consists of upper paper 1 wherein a layer containing a colorless color forming substrate 2 and a coupler 3 allowing said substrate 2 to form a color at the time of heating is provided on the front surface of a base sheet 1 and a layer containing the colorless color forming substrate 2, a microencapsulated colorless color forming substrate 2 and a heat-meltable substance 4 is provided on the back surface thereof and lower paper 11 wherein a layer containing one or more of the coupler 3 is provided on the front surface of a base sheet 1'. The heat-meltable substance 4 is a waxy substance having m.p. of 30-110 deg.C. |
