Abstract: In a process for producing light-sensitive polyamide layers which are suitable for producing photopolymeric printing forms or relief forms, a polyamide soluble or dispersible in the solvent, a photopolymerisable, low-molecular, ethylenically unsaturated compound, a photopolymerisation initiator and, if appropriate, further conventional additives are homogeneously mixed with one another, and the homogeneous mixture is, if necessary, freed of interfering volatile constituents by degassing and then formed to give the light-sensitive layer. According to the invention, the photopolymerisable mixture is, before forming to give the light-sensitive layer, heated largely with exclusion of oxygen and with simultaneous movement or further mixing in the melt for a period of 5 seconds to about 10 minutes to a temperature which is 20 to 80 DEG C above the softening point of the mixture.

Abstract: 1411841 Oxymethylene polymer-glass fibre compositions BADISCHE ANILIN- & SODAFABRIK AG 28 Feb 1973 [2 March 1972] 9722/73 Heading C3P Oxymethylene homo- and copolymers are compounded with glass fibres and a thermoplastic polyurethane. The composition may typically be obtained by melting the polymers in a twin-shaft extruder, adding the glass fibres, extruding the melt and injection moulding the resulting granules. In the examples trioxan-ethylene oxide or -dioxolan copolymers are mixed with glass fibres, sometimes having had a vinyl triethoxysilane or glycideoxypropyl trimethoxy silane treatment, and with polyurethanes derived from polyethylene glycol adipate, 4,4 1 -diphenylmethane diisocyanate and 1,4-butane diol or from an adipic acid/hexane diol/neopentylglycol copolyester, hexamethylene diisocyanate, and butane-diol-1,4.

Abstract: The invention relates to a process for the production of relief formes. After exposing layers which can be crosslinked by photopolymerisation to actinic light through an image, the uncrosslinked portions of the layers are washed out with hydrocarbon solvents or mixtures of hydrocarbon solvents and alcohols, certain hydrogenated petroleum fractions being used as hydrocarbon solvents. The process is suitable, in particular, for the production of flexographic printing formes.
