PROBLEM TO BE SOLVED: To prevent changes in characteristics of a photosensitive pressuresensitive recording medium even when the medium is stored under high humidity condition by forming such a structure that the photosensitive pressure-sensitive layer is interposed between high barrier films having low permeability for water vapor. SOLUTION: The photosensitive pressure-sensitive recording medium 10 consists of a light-transmitting first supporting layer 11, a white second supporting layer 12, and a photosensitive pressure sensitive layer 13 successively formed in this order. The photosensitive pressure-sensitive layer 13 is produced by dispersing microcapsules 14, coreactive material 15 in a binder which is prepared by adding a filler and viscosity controlling agent in various water-soluble resin emulsion such as polyvinylalcohol, and then applying the obtd. liquid on the first supporting layer 11. The photosensitive pressure-sensitive layer 13 is interposed between high barrier films having extremely low moisture permeability, so that even when the photosensitive pressure-sensitive recording medium 10 is stored under high humidity condition, intrusion of water vapor into the photosensitive pressure-sensitive layer 13 is almost prevented. Thereby, changes in the recording characteristics can be prevented. |
