Abstract: A 2-diazo-1,2-quinone compound having a substituent group containing an alkyl group which is substituted by at least one fluorine atom is described. This compound has a capacity to change its polarity when exposed to light. The invention also provides an image forming material in which the invention compound is added to at least one of laminated layers. When these laminated layers are exposed to light, the adhesiveness of the compound-containing layer to its adjoining layer is reduced effectively due to the polarity-changing ability of the compound, thus making the easy delamination of the layers possible. This compound is applicable to many instances in which image receiving sheets are used, such as the formation of a multi-color image by a transfer method (a color proof, for example) and the preparation of a printing plate of the delamination development type.

Abstract: An image-forming process comprises the steps of: forming an ink-receiving area and an ink-repelling area on a light-sensitive material by imagewise exposure; pressing on the ink-receiving area and ink-repelling area of the material an ink sheet comprising a support and an ink layer composed of a colorant and a polymer binder; removing the ink sheet from the material so that the ink layer of the ink sheet is transferred only onto the ink-receiving area of the material; pressing an image receiving sheet on the ink-receiving area having the ink layer and the ink-repelling layer of the material; and separating the image receiving sheet from the material so that the ink layer in the ink-receiving area is transferred onto the image receiving sheet. A similar image-forming process using a resist ink sheet is also disclosed.
