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.

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: 1292702 Disperse monoazo dyes FARBWERKE HOECHST AG 30 July 1970 [30 July 1969] 36842/70 Heading C4P The invention comprises monoazo dyes, free from acidic water-solubilizing groups, of formula wherein D is the radical of a benzene diazo component, Y is a H or halogen atom or an alkyl, alkoxy or acylamino group, Z is a H or halogen atom or an alkyl or alkoxy group, R is H or an alkyl group. A is alkylene and B and C are alkoxy or amino. The radical D and groups R, B and C (when amino) may be further substituted. The dyes are prepared by azo coupling and may be used to colour synthetic polyamide, polyester and cellulose acetate fibres in yellow, red and blue shades.

Abstract: Water-soluble surface-active esters of di- to hexa-hydric aliphatic alcohols which have been reacted with propylene oxide and/or ethylene oxide and thereafter with at least two moles of a carboxylic acid of up to 22 carbon atoms are useful for dyestuff preparations. These preparations have good flow properties even with high dyestuff concentrations and low contents of said esters and optionally other surfactants and can be used in dyeing and printing procedures, especially in printing pastes for printing transfer sheets.
