PROBLEM TO BE SOLVED: To provide a diazo copying material showing excellent image uniformity and excellent storage property for a long time. SOLUTION: This material consists of a photosensitive layer containing a diazo compd. and a coupler layer containing a coupling component, a copolymer comprising monomers having carboxylic acids or dicarboxylic acid anhydride as the structural component, and a basic component on a supporting body. In this case, the photosensitive layer or other layers contain a compd. expressed by the formula. In the formula, R is a straight-chain or branched alkyl group and (n) is a real number from 0 to 30. |
