The present invention relates to a photosensitive composition containing at least one compound selected from the group consisting of N-acyl amino acid derivatives, hydroxycarboxylic acids and their derivatives, condensates of an aliphatic or aromatic aldehyde with a polyhydric alcohol, acylated polysaccharides and metallic soaps. From the photosensitive composition of the present invention, moldings having excellent shape retentivity and/or compatibility of the components thereof with one another can be produced. Therefore, the production of moldings from a composition which has been heretofore impossible is made possible. Particularly a composition having a good moldability during the molding operation can be employed. The composition is useful for the preparation of printing plate materials having a good developability and printing plates, particularly flexible printing plates and flexographic printing plates, having an improved ink solvent resistance.
