    摘要: A photosensitive material for the production of color proofing films for multicolor printing, having (A) a transparent, flexible film support, (B) a photopolymerizable layer which contains (B1) a polymeric binder, (B2) a free-radical-polymerizable compound, (B3) a substituted bistrihalomethyl-s-triazine having an absorption maximum in the range from 300 to 380 nm and an absorbance of greater than 11,000 at the absorption maximum, and an absorbance of less than 1400 at 400 nm and above, as photoinitiator, and (B4) a dye or a colored pigment in a primary color of multicolor printing, and (C) a thermoplastic adhesive layer on the photo-sensitive layer. The material is processed by lamination onto an image-receiving material, exposure of the material and peeling apart of film support and image-receiving material, leaving the unexposed layer areas on the image-receiving material together with the adhesive layer. To produce a multicolored image, these steps are repeated with at least one further single-color sheet. The material has increased photosensitivity and gives color prints with lower background discoloration.

    摘要: This invention relates to negative working color proofing sheet constructions which, upon exposure to an actinic radiation source through a screened image, can accurately reproduce said image. The construction is useful as a color proofing film which can be employed to accurately predict the image quality from a lithographic printing process. The image is produced by forming a composite of a receiver sheet, an adhesive layer, a color layer and cover sheet. Upon imagewise exposure, a negative image appears on the receiver base after dry peel apart development.

    摘要: This invention relates to positive working color proofing sheet construction which, upon exposure to an actinic radiation source through a screened image, can accuratley reprouce said image. The construction is useful as a color proofing film which can be employed to accurately predict the image quality from a lithographic printing process. The image is produced by forming a composite of a receiver base, diazo or diazide layer, photopolymerizable layer and cover sheet. Upon imagewise exposure, a positive image appears on the receiver base after dry peel apart development.
