PURPOSE:To obtain the title paper capable of facilitating a handling and developing thereof at a relatively low pressure by coating a microcapsule contg. a dyestuff precursor and a microcapsule contg. a developer on a substrate respectively. CONSTITUTION:The substrate 1 is coated with the microcapsules 2, 3. The substrate is composed of a paper, a plastics and another suitable material. The microcapsule 2 is composed of a content 2a capable of changing a hardness by light irradiation and a thermoplastic resin 2b surrounding the content enclosed therein. The content 2a comprises the dyestuff precursor, the substance capable of changing the hardness by a light, and a photopolymerization initiator, and is color-developed by contacting it with a developer. The microcapsule 3 is composed of the developer 3a and the thermoplastic resin 3b enclosing the developer therein, and is softened the surface and the content enclosed therein by heating. Thus, the title paper capable of facilitating the handling and developing at a relatively low pressure is obtd. |
