    摘要: A process for producing an image which comprises the steps of:(1) applying to the surface of a substrate the surface of a photosensitive layer, the other surface of the photosensitive layer being adhered to a substantially transparent film support which is soluble or dispersible in a developer consisting essentially of a liquid capable of substantially dissolving or dispersing therein the areas of the layer other than those having a polymeric image produced by imagewise exposure in the step (2) below;(2) exposing the photosensitive layer, imagewise, to actinic radiation to form a polymeric image in the layer; and(3) washing away with the developer the film support and the areas of the layer other than those having the polymeric image to form an image of a polymeric material on the substrate. The photosensitive element having on its one side the above-mentioned specific film support and the process have a variety of applications and are useful for producing photoresists which are advantageously used for making printed circuit boards.
