    Abstract: Quaternary ammonium compounds of the formula where R1 and R2 are identical or different and each is H, halogen, phenyl, alkyl, alkoxy or alkylthio, R3 is H or alkyl, hydroxyalkyl, cycloalkyl or aralkyl, R4 and R5 are identical or different and each is alkyl, phenyl, cycloalkyl or aralkyl or R4 and R5 together are a -(CH2)4- bridge, a -(CH2)5- bridge or a -(CH2)2-O-(CH2)2- bridge, R6 is alkyl and X(-) is Cl(-), Br(-), I(-), CH3SO4(-) or C2H5SO4(-), a process for their preparation from Mannich bases of the formula and alkylating agents, and the use of these quaternary ammonium compounds as initiators for the photopolymerization of polymerizable mixtures containing olefinically unsaturated compounds, especially for the preparation of aqueous polymer dispersions or polymer solutions.

    Abstract: Binders which comprise (A) an aqueous emulsion of a copolymer A, having a glass transition temperature of 0-50 DEG C., of monoolefinically unsaturated carboxylic acid esters, with or without styrene, vinyl acetate, vinyl chloride and acrylonitrile, which copolymer contains, as copolymerized units, small amounts of monoolefinically unsaturated monocarboxylic acids and/or dicarboxylic acids and/or their amides (of which the nitrogen atoms may or may not be alkyl-substituted and/or alkylol-substituted) and small amounts of monomers containing carbonyl groups, (B) from 0.05 to 1 mole, per mole of carbonyl groups present in the copolymer A, of a water-soluble aliphatic dihydrazine compound and (C) from 0 to 0.02 mole, per mole of dihydrazine compound, of a water-soluble zinc, manganese, cobalt and/or lead salt, or particularly suitable for use in paints and pebble dash renderings, since they give films which adhere particularly well to alkyd resin primers and which show particularly little tendency to whitening.
