PURPOSE:To enable copying and image recording to be executed without trouble through softening of plastic grains at the time of use by coating a paper base with a dispersion containing photosensitive microcapsules enclosing a color forming element and a photosensitive resin, and the plastic grains larger in diameter than the microcapsules and softenable by an external energy, such as heat or light. CONSTITUTION:The photosensitive and pressure sensitive recording paper is obtained by forming a color developing agent layer 2 on the paper base 1, and the dispersion containing the photosensitive microcapsules 3, such as photohardenable ones, and the heat-softenable plastic grains 4 larger in diameter than the microcapsules 3 are applied to the layer 2. The microcapsules 3 enclose at least the color forming element and the photosensitive resin, and in addition, when needed, a photopolymerization initiator, a photosensitizer, a heat polymerization inhibitor or the like are incorporated. As the plastic grains 4, thermoplastic resins, such as polystyrene, a styrene-acrylic copolymer, polyester, polyvinyl butyral, polyamide, polyethylene, and an ethylene-vinyl acetate copolymer, are used. |
