Abstract
Disclosed herein are an image-forming material and a process for forming images, which can be applied to second originals used in the field of surveying. The image-forming material comprises a roughened plastics film substrate and a transparent resin layer, colored resin layer, photosensitive resin layer and protective layer formed one over another (in the order mentioned) on the roughened surface of the substrate, said four layers being so designed as un-exposed part thereof to be removed completely by dissolution or swelling during development after exposure to active rays. It permits the formation of a colored relief image without any dyeing step and gives rise to a good image free of base fogging without causing any decrease in printing sensitivity. The process for forming images comprises exposing the above-mentioned image-forming material to active rays and subsequently developing the exposed image-forming material with two kinds of developing solutions consecutively, thereby forming a colored positive relief image on the roughened plastics film substrate, said development causes the un-exposed parts of the transparent resin layer, colored resin layer, photosensitive resin layer and protective layer to be removed by dissolution or swelling.
