    摘要： Novel photopolymerizable recording materials, in particular for the production of printing plates and relief plates, can be developed with water or an aqueous alkaline solution and predominantly consist of a photoinitiator-containing mixture of (a) one or more low molecular weight compounds having one or more photopolymerizable olefinically unsaturated double bonds and (b) one or more organic polymeric binders and contain a bisacylphosphine oxide as the photoinitiator.These recording materials are useful for the production of printing plates and relief plates.

    摘要： Relief plates and printing plates are produced by a positive-working process, using a photopolymerizable layer which contains one or more photopolymerizable, olefinically unsaturated compounds, one or more photoinitiators which can be activated by UV light, and a combination of a phenothiazinium, phenoxazinium, phenazinium or acridinium dye with a mild reducing agent which, on exposure to visible light, is capable of reducing the dye in the excited electronic state. The photopolymerizable layer is exposed imagewise to light having a wavelength longer than 450 nm, and simultaneously or subsequently exposed uniformly to light having a wavelength of from 300 to 420 nm, after which the unpolymerized areas of the layer are removed.

    摘要： A photosensitive multi-layer material comprising a base and a photosensitive layer which has a polyamide binder and is soluble or dispersible in an alcoholic solvent contains two layers between the base and the photosensitive layer, namely (a) an adhesion-promoting layer, adjacent to the base, which is derived from a polyurethane binder, prepared by reacting a hydroxyl-containing epoxy resin and a polyisocyanate, and a pigment combination in which a white zinc sulfide pigment is the essential constituent, and (b) an adhesive layer, adjacent to the photosensitive layer, which consists of a baked mixture of an alcohol-soluble copolyamide and a melamine-formaldehyde resin.

    摘要： A workbench, in particular for welding and structural steel work, includes a frame assembly having opposing axial ends and including a pair of traverses respectively disposed at the axial ends, and a pair of spaced substantially parallel platforms for forming working surfaces for installation and placement of workpieces, with the working surfaces being expandable in all directions by retractable or detachably secured elements. One of the platforms is stationarily fixed on the traverses and the other one of the platforms is movably supported on the traverses for displacement in direction of the stationary platform. Extending laterally of the stationary platform is a support unit for attachment of accessories and including at least one support and a guide bar secured to the frame assembly and configured of polyhedral cross section for guiding the support in longitudinal direction.
