    摘要: A radiation-sensitive recording material, in particular for producing planographic printing plates, is disclosed. The material is composed of a layer support and a positive-working, radiation-sensitive layer having a rough surface containing at least one 1,2-quinonediazide as a radiation-sensitive compound, a polycondensate or polymer as a binder insoluble in water and soluble or swellable in aqueous-alkaline solutions, a dye and a filler. At a layer weight of 3 g/m.sup.2 or less, the radiation-sensitive layer comprises a silicic acid product having a mean grain size in the range from 3 to 5 .mu.m with an exclusion limit of 15 .mu.m as a filler in such a quantity that it exhibits a Bekk smoothness in the range from 20 to 100 seconds (determined according to DIN 53 107, Method A). The layer additionally comprises a surfactant having polysiloxane units. The recording material shows good copying properties and technical printing properties, such as an advantageous evacuation time, screen evenness, low susceptibility to air occlusions, good resolving power and a good coating structure. The invention also relates to a process for producing a planographic printing plated, using the recording material according to the invention.

    摘要: A light-sensitive composition for the preparation of printing plates and photoresists is described, which comprises as the light-sensitive compound a diazonium salt polycondensation product and as the binding agent a branched polyurethane resin which contains no terminal isocyanate groups and the terminal units of which are at least partially derived from dihydroxy compounds. The printing plates produced with this light-sensitive composition are easily developable with aqueous developer solutions and yield long press runs.

    摘要: Heat-curing, expanding mouldings based on solid polybutadiene rubber and vulcanization systems free from elemental sulfur are distinguished by the following advantageous properties: in the uncured state in which they are supplied, they have minimal rubber-elastic resilience and are readily formable. During the curing process, no unpleasant odors are given off and, after curing, a soft and elastic foam with a continuous outer skin is formed.
