Abstract: A dye and pigment dispersion containing a sulfuric acid semiester 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 translation: 含有式IN的硫酸半酯的染料和颜料分散体X是乙烯或丙烯，4-14个碳原子的R 1烷基，R 2氢或4-14个碳原子的烷基，n是2到25的整数 ，z为零或1〜8的整数，Me氢，碱，碱土金属，铵离子或有机碱的基团，以及通过在水溶液存在下研磨染料或颜料来制备该方法 的硫酸半酯。 与大多数已知的阴离子分散剂相比，得到的分散剂具有良好的分散效果和着色强度，并产生中性反应。

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.

Abstract: Stable dispersions of pigments are obtained by finely distributing inorganic and/or organic pigments in water and/or agents preventing or retarding the drying-up of the dispersions containing condensation products of aromatic hydroxy compounds and alkanals as well as surfactants, said condensation products and surfactants containing aliphatic carbon chains of more than 5 carbon atoms. The dispersions are compatible with hydrophilic and hydrophobic media.

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.
