    Abstract: Stabilised aqueous C14- to C22-alkyldiketene emulsions containing, as essential components, (a) 10 to 60 % by weight of at least one C14- to C22-alkyldiketene, (b) 1 to 10 % by weight of at least one protective colloid and (c) 0.1 to 20 % by weight of at least one ester of the formula in which R , R are C14- to C22-alkyl, in which case R and R must differ in the alkyl group by at least 4 C atoms, and/or denote identical or different C14- to C22-alkenyl groups, an ester of the formula R -O-CO-O-R (II), in which R and R are alkyl or alkenyl radicals having 2 to 22 C atoms or a urethane of the formula in which R , R and R are identical or different alkyl or alkenyl radicals having 2 to 22 C atoms, and the use of the compounds of the formula I to III as stabiliser for the preparation of alkyldiketene emulsions containing at least 10, preferably 16 to 40 % by weight of alkyldiketene in emulsified form.

    Abstract: Process for improving the printability of paper by a single- or two-sided application of aqueous coating materials consisting of a) 100 parts by weight of a finely dispersed pigment b) 5 to 70 parts by weight (based on solids) of a cationic aqueous polymer dispersion of a paper size and c) 0.01 to 10 parts by weight of a surfactant which interferes with the formation of the surface sizing and/or of a polymeric dispersant to the surface of the paper in a quantity of 0.5 to 4 g/m and drying the coated paper.

    Abstract: Sizes for paper are based on finely divided aqueous dispersions of copolymers which are obtainable by copolymerization of from 10 to 56 parts by weight of a monomer mixture of (a) from 20 to 65% by weight of (meth)acrylonitrile, (b) from 35 to 80% by weight of one or more acrylates of monohydric, saturated C3-C8-alcohols and (c) from 0 to 10% by weight of other ethylenically unsaturated copolymerizable monomers by an emulsion polymerization method in 100 parts by weight of an aqueous solution of from 1.7 to 25% by weight of a degraded starch having a viscosity eta i of from 0.12 to 0.50 dl/g, at from 40 DEG to 100 DEG C. in the presence of a peroxide-containing initiator.

    Abstract: PCT No. PCT/EP94/03584 Sec. 371 Date May 8, 1996 Sec. 102(e) Date May 8, 1996 PCT Filed Oct. 31, 1994 PCT Pub. No. WO95/13194 PCT Pub. Date May 18, 1995A process for the preparation of recording materials for inkjet printers by applying aqueous coating compositions to one or both sides of a sheet of paper which has been treated with size, where the coating compositions contain from 20 to 200 g/l of starch and from 1 to 50 g/l of a copolymer which is obtainable by emulsion copolymerization of 100 parts by weight of a monomer mixture comprising (a) from 10 to 65 parts by weight of styrene, alpha -methylstyrene, acrylonitrile and/or methacrylonitrile, (b) from 30 to 85 parts by weight of acrylic and/or methacrylic esters of alcohols having 1 to 18 carbon atoms, (c) from 5 to 25 parts by weight of monomers containing tertiary and/or quaternary amino groups, and (d) from 0 to 20 parts by weight of other monoethylenically unsaturated monomers in an aqueous medium in the presence of from 12 to 300% by weight, based on the monomers, of at least one natural or synthetic protective colloid.
