摘要：PURPOSE:To make handling easy by a method wherein after heating a recording material which installs a leuco dye coloring ;by oxidation, a micro capslue conteining a photoxidizer of this leuco dye, and a reducing agent capable of disturbing coloring of the leuco bye by acting on the photooxedize on a base material with a thermal head, a recording image is obtained by irradiation of light. CONSTITUTION:A recording material which established a microcapsule containing leuco dye coloring by oxidation and photooxidizer capable of oxidizing the leuco dye by irradiation of light, and reducing agent capable of disturbing coloring of the leuco dye with the photooxidizer by acting on the photooxidizer on a base material is heated with a therml head. Then, a recording image is obtained by irradiation of light capable of activating the photooxidizer on all surfaces. Polyurethane, polyurea, polyether, polycarbonate, ureaformaldehyde resin, etc, are exemplified as a wall material of the microcapsule capable of being used. Though the reducing agent is made to exist outside the capsule as a dispersed particle type, after dissolving the reducing agent in organic solvent insoluble or sed material. A recording method being thermal recording which can easily form a color less image on a colored background can be obtained thereby.
