ABSTRACT:
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 <0.5.
