摘要： The invention relates to a recording material having a dimensionally stable, two-dimensional support, preferably an aluminium support, and a negative-working, radiation-sensitive layer which comprises a diazonium salt, a polymeric binder and a sulphobetaine. In addition, the layer may also comprise a polymerizable monomer or oligomer and a photopolymerization initiator. The front of the recording material may be matted or pigmented, and the back may be coated with an organic polymeric material. The sulphobetaine improves the solubility of the diazonium salts in aqueous-alkaline developers without reducing the resistance of the offset printing plates produced from the recording material.

摘要： 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 &mgr;m or organic particles having a mean diameter of from 3 to 10 &mgr;m. 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.

摘要： The invention relates to a recording material having a substrate and a negative-working, radiation-sensitive layer which contains a diazonium salt, at least one film-forming, polymeric binder and organic colored pigments, on the surface of which an organic polymeric dispersant has been adsorbed and which are additionally dispersed in an organic polymeric binder which does not permanently combine with the pigments chemically or physically. The dispersant generally has groups, in particular primary, secondary or tertiary amino groups or derivatives thereof, which act as anchor groups on the colored pigment particles. The pigments themselves are preferably phthalocyanine pigments. As a result of the predispersing, aggregation of the pigment particles is effectively prevented so that uniform coloration of the radiation-sensitive layer is achieved. During development of the imagewise exposed recording materials, the colored pigment particles form virtually no insoluble precipitates. In the prepared printing plates, the printing parts are distinguished from the substrate material through being clearly visible and having high contrast.

摘要： The invention relates to a process for the production of a photosensitive recording material for the production of offset printing plates which comprises a dimensionally stable, two-dimensional support of a metal or metal alloy and a silver halide-containing, photosensitive layer on the front of the support and a layer which essentially consists of an organic polymeric material and is resistant to processing chemicals on the back of the support. The layer on the back of the support is applied before the photosensitive coating on the front. The invention furthermore relates to a corresponding recording material in which the layer on the back comprises at least one organic polymer having a glass transition temperature Tg of 50° C. or above. Due to the back coating, the formation of local elements between the metallic support and the silver-containing layer is reliably prevented when the recording materials are stacked. Coating flaws during application of the photosensitive coating have been virtually eliminated.

摘要： The invention relates to a recording material for the production of offset printing plates, having a web- or plate-form support, a radiation-sensitive layer on the front of the support and a continuous, pigment particle-free layer on the back of the support. The back layer essentially consists of an organic polymeric material having a glass transition temperature Tg of at least 45° C., and its surface has a Bekk smoothness of from 5 to 800 s. It also relates to a process for the production of this recording material.
