PROBLEM TO BE SOLVED: To obtain a photosensitive composition soluble in a high boiling point organic solvent such as propylene glycol, developable with water, excellent in safety and having high sensitivity, high adhesiveness to a substrate and good suitability to patterning by dissolving a derivative of a saponified product of polyvinyl acetate having specified constituent units in at least one organic solvent selected from a specified group. SOLUTION: A derivative of a saponified product of polyvinyl acetate having constituent units of formulae I, II, etc., is dissolved in at least one organic solvent selected from the group comprising solvents of formulae III, IV, etc., to obtain the objective photosensitive composition. In the formulae I-IV, (k) and (l) are each an arbitrary natural number, (l) may be 0, R1 is H or methyl, R5 and R6 are each H, methyl, ethyl or acetyl, R7 and R8 are each H, methyl or ethyl, (s) is an integer of 1-4 and (t) is an integer of 1-2. |
