PURPOSE:To obtain the titled paper having improved photosensitivity by coating a substrate body with a microcapsule contg. a photocurable resin, a dyestuff precursor and a photopolymerization initiator, and a developer, and by mounting a reflective layer on the substrate body. CONSTITUTION:The photosensitive layer comprising the microcapsule 2 contg. the photocurable resin, the dyestuff precursor and the photopolymerization initiator, and the developer 3 is mounted on the base paper 1 of the substrate body by coating it thereon, and the reflective layer 4 composed of an aluminium foil, etc. is provided on the lower side of the base paper 1 to form the titled paper. A latent image is formed by exposing the titled paper to a beam of light 5, thereby curing the microcapsule 2. At this time the microcapsule 2 is sufficiently cured by utilizing the reflection light 6 which is reflected with the reflective layer 4. The uncured microcapsule 2 is broken by a roller, thereby coloring the photosensitive layer by reacting a packed solution of the microcapsule and the developer 3. Thus, as the reflective layer is mounted on the substrate body, the sensitivity of the titled paper is improved by effectively utilizing the beam of light passed through the paper. |
