The invention relates to a radiation-sensitive material comprising A) a multilayer support material, B) a colored photopolymerizable layer, and C) an adhesive layer. The multilayer support material consists of at least two sheet-form materials, which are bonded to one another in such a way that the adhesion between the two sheet-form materials is less than the adhesion between the radiation-sensitive layer and the adjacent support material. The invention furthermore relates to a process in which a colored image, in particular a multicolored image comprising a plurality of primary-color images, is produced on an image-receiving material. The color images are produced by laminating a colored photopolymerizable layer onto the image-receiving material, exposing the material under the relevant master, in particular a color separation, developing the image by peeling-off the support film from the photopolymerizable layer together with the non-image areas, and, if desired, repeating the same steps with a photopolymerizable layer in a different color.

Radiation-sensitive material containing a multilayer support material

The present invention relates to a development material by means of a latent, colored image, obtained by laminating another, photopolymerizable material colored in a primary color onto an image-receiving material, peeling-off the film support and exposing the material under the associated negative color separation film, can be developed by laminating the development material onto the latent image and then peeling-off the development material together with the non-image areas. The invention also relates to a process for the production of a color proof using this development material in combination with photopolymerizable materials in the various primary colors.

Development material and process for the production of a negative color

A method for producing a positive as well as a negative multicolor color-proof image. The invention relates to a color proofing process in which a multicolor image is produced from a plurality of single-color images in register with the aid of a colored, photosensitive, photopolymerizable material on an image-receiving material. Depending on the processing variant, both positive and negative film masters can be processed, even simultaneously on a single receiving material, and it is not necessary for the emission spectrum of the light source to be variable.

Method for producing a positive as well as a negative multicolor

Disclosed are a photosensitive material and a corresponding method for making colour-proofing sheets for multicolour printing, comprising A) a transparent flexible polymeric support sheet, B) a photopolymerizable layer comprising B1) a polymeric binder, B2) a free-radically polymerizable compound, B3) a photoinitiator, and B4) a dye or pigment in a primary colour of multicolour printing, and C) a thermoplastic adhesion-promoting layer on the photosensitive layer, with a coating weight of 2 to 30 g/m.sup.2, characterized in that the thermoplastic adhesion-promoting layer includes 0.05 to 2.5% by weight of a colourless, transparent or white pigment having an average particle size which is less than 1% of the layer thickness and does not exceed 0.05 .mu.m and the ready-produced material has a slip friction coefficient of &lt;0.5.
