Abstract: The invention relates to aqueous binder-free pigment preparations containing (A) 1.0 to 75.0 wt. % of at least one organic or inorganic white or coloured pigment or a mixture of different organic and inorganic white or coloured pigments, (B) 0.01 to 8.0 wt.

Abstract: Polyesters according to the following formula (I) are described wherein R1 and R2 independently of one another are X—(OC2H4)n—(OC3H6)m wherein X is C1-4 alkyl, the —(OC2H4) groups and the —(OC3H6) groups are arranged blockwise and the block consisting of the —(OC3H6) groups is bound to a COO group or are HO—(C3H6), n is based on a molar average a number of from 12 to 120, m is based on a molar average a number of from 1 to 10, and a is based on a molar average a number of from 4 to 9. The inventive polyesters have an advantageous stability in alkaline environment, possess a beneficial solubility and advantageously are clearly soluble in alkaline compositions such as alkaline heavy duty washing liquids and also possess advantageous soil release properties.

Abstract: The invention is concerned with compounds according to the formula ##STR1## and their salts whereinR.sub.1 represents hydrogen or --SO.sub.3 H,R.sub.2 represents hydrogen, methyl, --NHCONH.sub.2 or --NHCOCH.sub.3 and,R.sub.3 represents hydrogen, C.sub.1-4 alkyl, preferably methyl or ethyl, or C.sub.1-4 alkyl substituted with CN, OH, Cl, F or --SO.sub.3 H.These compounds are useful as fiber-reactive dyestuffs in dyeing and printing hydroxy-group-containing and nitrogen-containing organic substrates.
