A B S T R A C T PHOTOSENSITIVE MATERIALS Photosensitive materials are described which may be used in a variety of applications such as making dry transfer materials, resist masks, printing plates and silk screen stencils. The material consists of two carrier sheets may be peeled apart and which are laminated together via at least two interlayers viz. a photosensitive layer and an image forming layer. Prior to exposure, if the carrier sheets are peeled apart the carrier sheet adjacent the photosensitive layer separates wholly from it leaving both photosensitive layer and image forming layer on the other carrier sheet. After exposure, if the sheets are peeled apart the whole of the photosensitive layer and at least part of the image forming layer remains attached to the carrier sheet adjacent the photosensitive layer. By incorporating adhesive in or adjacent the shearable image forming layer, the photosensitive material may constitute a material from which dry transfers may be manufactured simply by imagewise exposure and peeling apart.
