PURPOSE:To embody excellent resistance to plasticizer by a method wherein at least one of compound represented by a specified formula as electron accepting compound is contained in heat-sensitive recording material, which utilizes thermal coloring reaction between colorless electron donating dye and the electron accepting compound. CONSTITUTION:In the heat-sensitive recording material concerned utilizing the thermal coloring reaction between colorless electron donating dye and electron accepting compound, at least one of compounds expressed by formula I as the electron accepting compound is contained. In order to manufacture the heat-sensitive recording material concerned, the colorless electron donating dye, the electron accepting compound and other auxiliary component are bound and supported on a support. As the binder in this case, various ordinary binders are adequately used. Thus, the stability of image part and, at the same time, the stability of ground of ground part are improved. |
