    Abstract: In order to prepare an antibacterial and fungicidal polymer dispersion, a polymer dispersion is mixed with an amount of a protective polymer which is dispersible in the polymer dispersion, said amount being sufficient to attain an antibacterial and fungicidal effect. The protective polymer comprises: between 3 and 60 wt %, relative to the total weight of components a) and b) without metallic ions, of at least one C3 to C7 alpha, beta-monoethylenically unsaturated mono or dicarboxylic acid which is partially or completely neutralized or can be present as an anhydride, as component a); between 97 and 40 wt %, relative to the total weight of components a) and b) without metallic ions, of at least one C1 to C20 alkyl(meth)acrylate, of a C1 to C20 carboxylic acid vinyl ester, of a vinyl aromatic containing up to 20 carbon atoms, of an ethylenically unsaturated C3 to C6 nitrile, of a vinyl halide or a non-aromatic C4 to C8 hydrocarbon and at least two conjugated double bonds or ethylene or propylene as component b); between 0 and 50 wt %, relative to the total weight of components a) and b) without metallic ions, of at least one further ethylenically unsaturated monomer, as component c); and between 0 and 20 wt %, relative to the total weight of components a), b) and c) without metallic ions, of at least one cross-linking polyfunctional monomer, as component d). Between 1 and 100 mol % of the acid groups are converted into salts of at least one antibacterial and/or fungicidal metallic ion.

    Abstract: The use of light-sensitive recording element as artistic medium for producing and reproducing free-hand drawings is claimed. The element consists of a dimensionally stable base and a negative- or positive-working light-sensitive layer, which is sensitive to UV and/or visible actinic light. Pref. the element may also have an optically transparent top coat contg. polymer(s) forming a tear-proof film. The drawing is made with a material which is opaque to the actinic light concerned and does not damage the surface of the recording element. The element is then totally exposed with actinic light, which causes solibility differentiation between the exposed and unexposed areas. One of these areas is washed out with a suitable developer, giving a printing plate with the motif, which is used for duplicating the motif. USE/ADVANTAGE - The technique is useful for making flat and cylindrical, gravure, offset, letterpress or flexographic printing plates. Accurate reprodns. can be obtd. without the cost of photomechanical reprodn..

    Abstract: Use of an aqueous dispersion containing from 5 to 80 % by weight of a copolymer A) having a glass transition temperature of from 50 to 150 DEG C, and from 95 to 20 % by weight of a copolymer B) having a glass transition temperature of from -50 to +50 DEG C, in which the glass transition temperatures of the two copolymers differ by at least 20 DEG C, and at least one of the two copolymers has a content of an ethylenically unsaturated C3-C5-mono- or dicarboxylic acid, or the anhydride thereof, of from 3 to 70 % by weight, based on the particular copolymer, and the weight data of the copolymers A) and B) relate to the sum of A) and B), as a heat-sealable coating.
