| abstract |
A photosensitive composition of this invention comprises: (a) a photosensitive diazo resin represented by the following general formula (I):wherein R<sup>1</sup>, R<sup>2</sup> und R<sup>3</sup> each represents a hydrogen atom, an alkyl or alkoxy group, R represents a hydrogen atom, an alkyl or phenyl group, X represents PF<sub>6</sub> or BF<sub>4</sub> and n represents a number of 1 to 200, in which a resin with the number n in the above formula being 5 or more is contained by more than 20 mol%,(b) an oleophilic high molecular compound with hydroxyl group and(c) a high molecular organic acid without hydroxyl group, and in which the content of the ingredient (c) is from 1.5 to 30% by weight based on the solid matter in said composition.The photosensitive composition of this invention can provide a photosensitive layer having high sensitivity and being excellent in storage stability and developability as well as excellent in the film strength. |
