    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: 1518434 Disperse dye compositions HOECHST AG 27 May 1976 [28 May 1975] 22080/76 Heading D1B Solid or liquid disperse dye preparations used in the pad-dyeing and printing of synthetic and semi-synthetic fibrous materials contain 5-60% by weight of one or more disperse dyes, 5 to 90% of a dispersing agent, 0-90% of a wetting agent, 0-60% of a grinding auxiliary 0-90% of water and 0.5 to 30% by weight (referred to the weight of the solid or liquid dyestuff preparation) of at least one organic phosphoric acid ester of formula: or of formula: in which n is 2 or 3 m is 0 or an integer 1 to 10 and R is an alkyl radical having 8 to 20 carbon atoms or a mixture of phosphoric acid esters of the above two formulae. The preparations may be obtained by adding the esters to the other ingredients before, during or after fine division thereof. These preparations have improved safety and higher dyeing yield. -

    Abstract: A stable, liquid, aqueous dyeing composition consisting of (a) 3 to 25 percent by weight of at least one fibre-reactive dyestuff of the formula (HO3S)m-F-Zn IN WHICH F represents the radical of a dyestuff chromophore of an anthraquinone-, monoazo-, disazo-, trisazo- or phthalocyanine dyestuff, Z represents a fibre-reactive group, m stands for an integer from 1 to 6 and n stands for an integer from 1 to 3, (b) 3 to 25 percent by weight of at least one disperse dyestuff, (c) 0.5 to 5 percent by weight of a buffer substance, (d) 3 to 40 percent by weight of a dispersing agent, wetting agent, antifreezing agent or preservative or mixtures thereof, and (e) water, and having a pH value between 4 and 7, said dyeing compositions being suitable for the dyeing or printing of blends of fibres containing on the one hand wool, silk, fibres of native or regenerated cellulose, and on the other hand synthetic polyamide, polyacrylonitrile or linear polyesterfibres.
