    Abstract: The invention relates to polymers made out of a poly(meth)acrylic acid main chain, in which, in relation to the main chain, 0 to 30 wt. % of the (meth)acrylic acid basic units can be replaced by maleic acid (anhydride) basic units, fumaric acid basic modules or mixtures thereof; and 0 to 10 wt. % of the (meth)acrylic acid basic units can be replaced by other copolymerisable, ethylenic basic units. The polymers are also made of side chains in the form of C1-30-alkylpoly-C2-4-alkylglycols which are bound to t he main chain by means of ester groups and which have an average molecular weig ht of 250 to 10,000. The main chain and side chains make up 1 to 19 wt. % and 8 1 to 99 wt. % of the polymer respectively. The ratio and the average molecular weight of the side chains are chosen in such a way that the polymer contains free carboxyl groups. Said polymers are used as controllable dispersing agen ts for detergents or constituents thereof.

    Abstract: The invention relates to a microcapsule preparation containing microcapsules having a core made from a hydrophobic material and a capsule coating made from a polymer which in a polymerized form contains at least 1 wt. % cationogenic monomers and/or multi-ethylenically unsaturated monomers whose unsaturated points are linked by means of successive chemical bonds, whereby at least one bond can be hydrolyzed by acid. The invention also relates to a microcapsule preparation containing microcapsules having a core which is made of a hydrophobic material comprising at least one olfactory agent or fragrant agent, and a capsule coating made from a polymer which in a polymerized form contains at least 1 wt. % anionogenic monoethylencially unsaturated monomers and/or multi-ethylenically unsaturated monomers whose unsaturated points are linked by means of successive chemical bonds, whereby at least one bond can be basically hydrolyzed. The microcapsules can be used in detergent or cleaning agents.

    Abstract: An electrophotographic recording medium which consists essentially of an electrically conductive base and a photosemiconductive double layer which comprises a first layer containing charge carrier-producing dyes, and a second layer containing one or more compounds which are charge carrier-transporting when exposed to light, wherein the charge carrier-producing dyes are those of the general formula I I where R1, R2, R3 and R4 are each hydrogen or a non-ionic substituent, X and Y are each the radical of a methylene-active compound, or of an aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic amine or hydrazine, and Z is hydrogen, methyl or phenyl, and the production of this recording medium.

    Abstract: Production of an electrically conductive surface layer on moulded articles consisting of plastics which are soluble or can be swelled in organic solvents, the conductivity of which surface layer is based on a system embedded therein of… - organic electron acceptors (I) on the one hand and… - organic electron donors (II), iodides (III) or mixtures of (II) and (III) as electron donors on the other hand,… in that the moulded articles are treated with organic solutions of these components. … The products of the process have a surface resistance between 10 and 10 ohms and have the advantage that the other characteristics of the moulded articles are virtually uninfluenced by the means (I) to (III).
