<P>PROBLEM TO BE SOLVED: To provide a pressure-sensitive recording sheet which, even after storage for a long period and exposure to sunlight and light from a fluorescent lamp for a long period of time, does not cause the coloration of a microcapsule coated face and can realize the formation of a good developed color image. <P>SOLUTION: This pressure-sensitive recording sheet includes a microcapsule prepared by forming a wall membrane of an amine-aldehyde polycondensate in a system in which a hydrophobic core material has been dispersed or emulsified. In the microcapsule, the hydrophobic core material contains 3,7- bis(dimethylamino)-10-benzoylphenothiazine as an electron-donating dye and a metallic soap. <P>COPYRIGHT: (C)2003,JPO |
