PURPOSE:To provide a new thermosensitive recording material, new thermodeveloping photosensitive material and new positive thermodeveloping photosensitive material. CONSTITUTION:The recording material consists of a supporting body and a coating layer containing org. silver salt, heat solvent and 1,3-sulfurnitrogen compd. which causes cleavage reaction in the presence of silver ion or soluble silver complex. A picture image is formed by heating the recording material in the image pattern in a state substantially containing no water nor base. Or the recording material has a coating layer containing 1,3-sulfur-nitrogen compd, org. silver salt, heat solvent and silver halide, reducing agent. A picture image is formed by exposing in a pattern and then heating in a state substantially containing no water nor base, or by exposing and heating at one time. |
