    摘要: A process for producing negative copies is disclosed in which a light-sensitive or radiation-sensitive recording material comprising a layer support and a normally positive-working light-sensitive or radiation-sensitive layer applied thereto is irradiated imagewise, thermally treated, irradiated overall and then developed with an alkaline developer. Thermal treatment is carried out with water or with an aqueous solution, at temperatures in the range from about 50.degree. to 100.degree. C., preferably from 60.degree. to 90.degree. C., within a period of time varying between about 1 second and 5 minutes, preferably between 5 seconds and 1 minute, overall irradiation is performed on the optionally still hot recording material and development is thereafter carried out within a period of time varying between about 10 seconds and 2 minutes, preferably between 15 seconds and 1 minute. The process can be carried out according to the customary procedure known in the practice of positive processing, and results in perfect printing stencils.

    摘要: The invention relates to a non-continuous matte layer that can be used with a recording material having a substrate and a radiation-sensitive layer which contains a 1,2-naphthoquinone-2-diazide and an organic, polymeric binder which is insoluble in water but soluble in aqueous alkaline solutions. This matte layer comprises 100 to 10,000 particles per square centimeter which have a mean diameter of less than 40 .mu.m and a maximum diameter of less than 80 .mu.m and a mean height of 2 to 6 .mu.m and a maximum height of 10 .mu.m, and contains a resin which has up to 0.80 mmol of acid groups and/or salt groups per gram. The matte layer is obtained by spraying on and drying an aqueous, anionically or anionically/nonionically stabilized dispersion of the resin.

After imagewise exposure to a laser, the recording material prepared using this mixture can be readily developed with an aqueous alkaline solution without additional processing steps (such as post-bake or postexposure).

    摘要: A photosensitive recording material is described which has a layer base, a negative-working photosensitive layer containing a diazonium salt and a water-insoluble polymeric binder which is soluble or swellable in aqueous alkaline solutions, and a discontinuous top layer which forms a rough surface and which is composed of particles of a water-insoluble polymer which is dispersible in water in the presence of anionic or anionic/nonionic dispersants and which has a content of free acid groups or acid groups neutralized by salt formation of less than 0.8 mmol/g, the mean height of the particles being 2 to 6 .mu.m, the maximum height less than 10 .mu.m, the mean horizontal diameter less than 40 .mu.m, the maximum diameter less than 80 .mu.m and the number of particles being 100 to 10,000 per cm.sup.2. The material is suitable for the production of planographic printing plates and requires only short vacuum times in a vacuum-operated copying frame. The material can be developed without residue after exposure, the rough surface remaining intact at the image areas.
