PURPOSE:To prepare a fixable heat-sensitive recording material, by a method wherein a light bridging resin is caused to exist in a heat-sensitive layer in which a leuco dyestuff layer and an oxidized material layer are laminated. CONSTITUTION:A photo bridging resin, such as compounds, wherein a sensitizer such as benzophenone is mixed to a butadiene polymer (component) containing high 1,2-structure, or components, wherein a photopolymerization initiator such as benzoin is mixed to an unsaturated polyester polymer, is used. Or, in a heat- sensitive recording materiual which is prepared such that a thin layer consisting of a leuco dyestuff, such as 3,3-bis(p-dimethylaminophenil)-6-dimethylaminophthalid, and a thin layer consisting of an acid material, such as alpha-naphthol, are laminated on a support product, said photo bridging resin is contained in at least either of the two layers, or it may be laid between the two layers. |
