PURPOSE:To enhance the presevability of a recording image by arranging a recording layer containing a photosensitive diazo compd., a coupling component forming a color upon the reaction with the diazo compds. and a compd. represented by a specific chemical formula on a support. CONSTITUTION:A diazo type recording material is constituted by arranging a recording layer having a specific compsn. on the upper surface of a suppot. The recording layer is formed from a compsn. consisting of a photosensitive diazo compd. included in a microcapsule, a coupling component forming a color upon the reaction with the diazo compd. under heating and a compound represented by chemical formula (wherein R1-R4 are respectively a hydrogen atom, an alkyl group, an alkoxy group, an aryloxy group or the like and may be same or different, R5 is an alkylene group which may contain an oxygen atom or a sulfur atom and an aromatic ring A or B is a benzen ring or a naphthalene ring). |
