    摘要: A process for producing a colored image by laminating a light-sensitive material comprising a temporary support film (i), a colored light-sensitive layer and a heat-activable adhesive layer onto an image-receiving material at elevated temperature and under pressure, subjecting the light-sensitive layer to imagewise exposure and developing by peeling off the support film, characterized in that the image-receiving material comprises a light-sensitive compound which, on irradiation, releases a gas which remains trapped in the image-receiving material in the form of gas bubbles. The advantage of the process is that, on irradiation under a halftone original, the size of the halftone dots in the coloured image produced on such an image-receiving material is optically reduced.

    摘要: A process for the production of a color image is described, in which a photosensitive material that has a temporary support film, a colored photosensitive layer and an adhesion-promoting layer that can be activated by heat is laminated at high temperature and under pressure with an image-receiving material which carries, on a support, a pigment layer containing a white pigment. The photosensitive layer is exposed imagewise and developed to produce an image, the temporary support film is peeled off from the image-receiving material before or after exposure to light and, if required, these steps are repeated with at least one further photosensitive material whose colored layer has another color to produce a multi-colored image. The process gives color images having a smaller dot enlargement compared with a halftone original and is particularly suitable for the color testing of copy for multicolor printing.

    摘要: The invention relates to a photosensitive material for the production of color proofing films for multicolor printing comprising:A) a transparent, flexible film support,B) a photopolymerizable layer containing:B1) a polymeric binder,B2) a free radical-polymerizable compound,B3) a compound which is capable of initiating the polymerization of (B2) on exposure to actinic light, andB4) a dye or colored pigment in a primary color of multicolor printing, andC) a thermoplastic adhesive layer on the photosensitive layer,which contains at least about 1.5% by weight of a water-soluble, colorless, low-molecular-weight salt whose aqueous solution is not highly acidic.The material is processed by lamination onto an image-receiving material, exposure and peeling apart of the film support and the image-receiving material, the unexposed areas of the layer and the adhesive layer remaining on the image-receiving material. The addition of the salt to the adhesive layer substantially reduces the adhesion between this layer and the exposed areas of the photopolymerizable layer.
