A photosensitive image-forming material having a photosensitive layer, said photosensitive layer comprising a photosensitive resin resulting from the reaction of a hydroxyl-containing polyester precursor composed of dicarboxylic acid units derived from a dicarboxylic acid having a photosensitive unsaturated double bond adjacent to an aromatic ring and glycol units with a chain extender having in the molecule at least two functional groups capable of reacting with the hydroxyl groups of the polyester precursor.

Photosensitive image-forming material having a layer of photosensitive

A photosensitive image-forming material developable with aqueous alkali developers, which is characterized in that the photosensitive resin having the structural units represented by the general formula ##STR1## (wherein A represents a linear polyester structural unit containing in its main chain the dicarboxylic acid unit having a photosensitive, unsaturated double bond adjacent to the aromatic ring, and R.sub.1 represents a tetravalent organic group) is contained in the photosensitive layer.
