A photo-sensitive resin material which comprises, in order, a photo-sensitive resin layer (1); a light-permeable protective film layer (3), attached to the resin (1), which is non-tacky and soluble in, or swellable with, water or an alcohol; a release layer (5); and a sheet material (4), in which the protective film layer (3) can remain attached to the photo-sensitive resin layer on removal of the sheet material (4). A backing material (2) is often included. The novel resin material, despite including a photo-sensitive resin layer which may have a tacky surface, allows ready positioning of a negative thereon, without causing damage. |
