    Abstract: Coating compsn. contains (A) a film-forming resin, (B) a cellulose ester, (C) solvent, (D) metal pigment and opt. (E) crosslinkers and (F) further lacquer additives and of the type esp. to give a multi-layer coating with a base layer and opt. a clear topcoat. (i) the cellulose ester (B) has an acetyl content of 2-30 (pref. 2-5) wt.%, a butyryl content of 17-53 (pref. 47-53) wt.% and an average mol.wt. of at least 25000, pref. 30000-60000; and (ii) this cellulose ester is introduced into the coating compsn. in the form of a pasty, thixotropic pre-mix (e.g. with the crosslinkers). The solids content of the compsn. is pref. 15-30 wt.%. The cellulose ester pre-mix pref. contains a diluent which swells the cellulose ester, esp. an aromatic or aliphatic hydrocarbon or a higher alcohol. alcohol.

    Abstract: Copolymers based on (A) 5-95% by weight of at least one polymerizable carbamoyloxyalkyldicarboxylic acid ester, carrying hydroxyl groups, of the general formula I in which R1 represents hydrogen or alkyl or hydroxyalkyl having in each case 1 to 30 carbon atoms in the alkyl radical, R2 represents alkyl or hydroxyalkyl having in each case 1 to 30 carbon atoms in the alkyl radical, or the radical subject to the proviso that R1 is hydrogen and x is an integer from 2 to 10, R3 represents linear or branched alkylene having 2 to 5 carbon atoms, R4 represents hydrogen or methyl and R5 represents hydroxyalkyl or hydroxyaminoalkyl having in each case 2 to 20 carbon atoms in the alkyl radical, or an alkyl radical of this type which also contains ester groups and/or ether groups, and (B) 5-95% by weight of at least one copolymerizable monomer belonging to the group comprising (a) alpha , beta -olefinically unsaturated monocarboxylic acid and alkyl and hydroxyalkyl esters thereof having in each case 1 to 18 carbon atoms in the alkyl radical, and amides and nitriles thereof, and also monoalkyl and dialkyl esters of alpha , beta -olefinically unsaturated dicarboxylic acids having 1 to 18 carbon atoms in the alkyl radical, (b) vinyl-aromatic monomers, (c) vinyl esters of organic monocarboxylic acids having 1 to 18 carbon atoms in the carboxylic acid radical, and (d) glycidyl esters of unsaturated monocarboxylic and/or dicarboxylic acids, the sum of the components (A) and (B) being in all cases 100% by weight, and a process for their preparation. The copolymers are used for the preparation of shaped articles and/or coatings which have excellent properties.
