摘要： A photosensitive composition including a water-soluble aromatic diazo compound having at least two diazo groups and lactic acid, hydroxyacetic acid or, a mixture thereof in an amount of at least one third by weight of the diazo compound. The photosensitive composition is in the form of a liquid or paste, is thus easy to handle, is suitable for use in the production of photosensitive printing plates, and has good storage stability.
