PURPOSE:An inexpensive photosensitive material, obtained by reacting a specific diamine component with a carboxylic acid anhydride (derivative) component, having improved storage stability and containing a photosensitive polyamic acid without any problems in operation and environmental protection. CONSTITUTION:A photosensitive material containing a photosensitive polyamic acid obtained by reacting (A) an aliphatic diamine, e.g. ethylenediamine and/or alicyclic diamine, e.g., 1,4-diaminocyclohexane and, as necessary, an aromatic diamine, e.g. 2,4-diaminotoluene, and/or heterocyclic diamine, e.g. 2,6- diaminopyridine, with (B) a tetracarboxylic acid dianhydride and/or tricarboxylic acid anhydride and/or tricarboxylic acid anhydride derivative having carbonyl groups and tricarboxylic acid anhydride and/or tricarboxylic acid anhydride derivative having no carbonyl group. |
