Estimating the term…
The invention relates to a radiation-sensitive recording material for the production of offset printing plates having a dimensionally stable support, a radiation-sensitive layer located on the front of the support, and a layer which comprises an organic polymeric material having a glass transition temperature of 35° C. or above and in which pigment particles are embedded and which is resistant to processing chemicals and is located on the back of the support. The pigment particles are preferably silica gel particles having a mean diameter of from 0.1 to 50 μm or organic particles having a mean diameter of from 3 to 10 μm. The image layer on the front may be matted or pigmented. The back coating enables the recording material to be stacked without separating paper. The image layer located on the front is not scratched by the pigmented back coating during storage and transport and during removal from the stack.
A recording material for the production of offset printing plates comprising a dimensionally stable support, a radiation-sensitive layer located on the front of the support, and a back coating which comprises an organic polymeric material located on the back of the support, wherein the glass transition temperature of the organic polymeric material is 35° C. or above, and the back coating comprises from 0.5 to 50% by weight of a pigment and is resistant to processing chemicals.
