PURPOSE:To enhance developed color density without deteriorating developed color staining by providing an intermediate layer containing inorg. or org. pigment on a support and laminating a recording layer consisting of a microcapsule containing a color former and paint containing a coupler to said layer. CONSTITUTION:An intermediate layer containing inorg. and/or org. pigment is provided on a support and a monolithic recording layer consisting of a microcapsule containing a color former and paint containing a coupler is laminated to said intermediate layer to prepare color self-developable pressure-sensitive recording paper. As a concrete example of the inorg. pigment, there are calcium carbonate, talc, silica and barium sulfate and, as a concrete example of the org. pigment, there are polystyrene, polyvinyl toluene and a styrene/divinyl benzene copolymer all of which have melting temp. of 100 deg.C of higher. The coating amount of the intermediate layer is pref. 1-20g/m<2>. |
