PURPOSE:To improve transparent stability of a photosensitive thermal sensitive recording material by providing a photosensitive thermal sensitive layer containing microcapsules containing diazo compound and coupler together with phenol compound, etc., on one side face of a support. CONSTITUTION:Microcapsules containing at least diazo compound, and emulsified dispersant obtained by dispersing coupler together with phenol compound and/or salicylic acid derivative metal salt after dissolving it in a solution difficult or insoluble in organic solvent are mixed to prepare a coating solution. Then, the one side face of a support is coated with the solution, a transparent photosensitive thermal sensitive layer is laminated, and dried to obtain a photosensitive thermal sensitive recording material. The example of the diazo compound includes, for example, aromatic diazonium salt, diazosulfonate compound, and the example of the coupler includes, for example, resorcin, fluoroglucin, etc. |
