Abstract: A photosensitive recording element which is suitable for the production of printing plates or resist images possesses a photopolymerizable recording layer which is applied to a dimensionally stable base, can be developed in an aqueous alkaline medium and contains, as a polymeric binder, one or more film-forming copolymers which are insoluble in water but soluble or dispersible in aqueous alkaline solutions and consist of from 10 to 50% by weight of one or more N-vinylamides, preferably N-vinylcaprolactam and/or N-vinylpyrrolidone, from 5 to 30% by weight of acrylic acid and/or methacrylic acid, from 30 to 80% by weight of one or more comonomers from the group consisting of the vinyl aromatics and (meth)acrylates of monoalkanols and from 0.2 to 5% by weight of an olefinically unsaturated compound which contains basic nitrogen atoms and has a pKa>4.

Abstract: A process for the preparation of insoluble, only slightly swellable, granular polymers of basic vinyl-heterocyclic compounds and of their copolymers with up to 30% by weight of copolymerizable monomers and 0.1-10% by weight of crosslinking agent by exclusion of (atmospheric) oxygen from the mixture of monomer and crosslinking agent, without addition of any initiator or catalyst, and the use of the polymers obtained as ion exchangers, adsorbents and carriers for proteins.

Abstract: Photopolymerizable recording materials which are suitable for the production of photoresist layers, and contain one or more thermoplastic vinyl polymers as the binder, one or more low molecular weight, ethylenically unsaturated, photopolymerizable compounds and one or more photoinitiators, with or without other, conventional additives and/or assistants, have excellent adhesion to metallic substrate surfaces if the binder employed is a vinyl polymer which possesses amino and/or imino groups.

Abstract: In dry film resists possessing a solid photopolymerizable resist layer, which is applied on a temporary base and can be developed with aqueous, in particular aqueous alkaline, media, and, if required, a cover sheet on the resist layer, the said resist layer is built from a homogeneous mixture of (a) not less than 40% by weight of one or more oligomers which contain free carboxyl groups and more than two acryloyl and/or methacryloyl groups and are soluble or dispersible in aqueous alkaline solutions, (b) from 1 to 35% by weight of one or more film-forming compatible polymers which are soluble in aqueous media, (c) from 1 to 30% by weight of one or more compatible photopolymerizable monomers, (d) from 0.001 to 10% by weight of one or more photoinitiators and (e) from 0 to 30% by weight of further additives and/or assistants. Resist images are produced on a substrate by a process employing photopolymerizable resist layers of the type stated above.

Abstract: An insoluble biocatalyst is prepared by forming a mixture consisting essentially of the biocatalyst, one or more water-soluble compounds having two or more acrylamide or meth-acrylamido groups and one or more water soluble amines possessing two or more hydrogen atoms bonded to an amine nitrogen, and forming a gel from the mixture. The water-soluble amine is selected from ammonia, lower diamines, lower polyamines, primary monoamines, polyethyleneimine and polyvinylamine. Beads containing the biocatalyst may be formed by suspending the mixture in a water-immiscible solvent to form droplets prior to gelling. The biocatalyst may be an enzyme, cells or cell fragments.
