    Abstract: Watersoluble oxalkylated novolaks of the formula (I) wherein R1 is alkyl of 1 to 18 carbon atoms, R2 is hydrogen or R1, X is ethylene or propylene, m is 6 to 100 and n is 1 to 12, are preparation agents for disperse dyestuffs. Disperse dystuff preparations containing these compounds have a stable and uniform distribution of the dyestuff particles, even with high dyestuff concentrations, and show good dyeing properties, low or no foam in dyebaths and useful viscosities in printing pastes.

    Abstract: A dye and pigment dispersion containing a sulfuric acid semi-ester of the formula IN WHICH X is ethylene or propylene, R1 alkyl of 4 to 14 carbon atoms, R2 hydrogen or alkyl of 4 to 14 carbon atoms, n an integer of 2 to 25, z zero or an integer of 1 to 8 and Me hydrogen, alkali, alkaline earth metal, an ammonium ion or a radical of an organic base, and a process for preparing it by grinding the dye or pigment in the presence of an aqueous solution of said sulfuric acid semi-ester. The dispersing agents obtained have a good dispersing effect and tinctorial strength and give a neutral reaction in contrast to most of the known anionic dispersing agents.

    Abstract: Dispersions containing (a) a pigment, (b) an oxalkylated novolak, (c) urea and/or a compound containing at least 2 long-chain aliphatic groups and which are connected via a bridge member containing ester and/or amide groups, and (d) water and/or agents retarding drying up, and, optionally, usual adjuvants, are useful for pigmenting natural or synthetic materials, especially aqueous systems containing cellulose ethers.
