    摘要： Finely divided mixtures of 97-10% by weight of at least one amphiphilic polymer whose softening point is above 35.degree. C., and 3-90% by weight of at least one inorganic solid with a particle size not exceeding 500 .mu.m are prepared by heating the two components to a temperature which is above the softening point of the polymer, mixing the components, dispersing the melt and rapidly cooling to a temperature at which virtually no inhomogeneity occurs and, where appropriate, further comminuting the particles at temperatures below 50.degree. C. to a particle size of from 50 .mu.m to 5 mm, and are used as additive to detergents.

    摘要： 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.

    摘要： Photocured layers possessing a defined controllable hardness are produced by exposing a layer of a photopolymerizable or photocrosslinkable mixture, which contains a partially crystalline polymeric binder possessing olefinic double bonds capable of undergoing polymerization, to actinic light, by a method in which the photocurable layer, prior to exposure to actinic light, is subjected to a heat treatment in which the partially crystalline parts of the polymeric binder are partially or completely fused.
