ABSTRACT:
A multi-color image forming material which is in the form of multiple layers on a support, and having, at least two photosensitive layers, the farthest layer from the support being the uppermost photosensitive layer, the photosensitive layers being formed from a water-soluble resin having photocrosslinking ability with diazo resin, a photosensitive water-soluble, organic solvent insoluble diazo resin, and a water dispersible coloring agent which can produce a color tone, each photosensitive layer having a coloring agent which can produce a different color tone; and at least one intermediate layer, each intermediate layer being positioned between each photosensitive layer and the next adjacent photosensitive layer, the intermediate layer being formed from a hydrophobic, water-resistant, organic solvent softenable resin.
