The present invention relates to the use of a combination of a free fluorescent whitening agent and cationic polymer as a brightening agent for a synthetic single or blended textile, especially polyester textile, and to a corresponding brightening agent as well as a laundering process for brightening a synthetic, single or blended textile, which is characterized by a) preparing a composition by contacting a free fluorescent whitening agent with a cationic polymer, and b) treating said synthetic, single or blended textile with the composition prepared in step a).

Laundering process for whitening synthetic textiles

Disclosed are polymeric dyes of formula (1a), (1b), or (1c); wherein the substituents and variables are defined in the claims and specification. The dyes are distinguished by their depth of shade and their good fastness properties to washing, such as, for example, fastness to light, shampooing and rubbing. 

Polymeric hair dyes

A detergent composition comprising i) 1-70% of an anionic or nonionic surfactant, ii) 1-75% of a builder, iii) 0.001-5% of at least one compound of Formula (1) wherein R represents a C-Calkyl residue and M represents hydrogen or an alkali metal cation, optionally with further FWA's, iv) 0-30% of a peroxide, v) 0-10% of a peroxide activator, vi) 0-5% of a bleaching catalyst and vii) 0-5% of an enzyme, each component by weight, based on the total weight of the detergent composition, use thereof for domestic washing of textile fibre materials and a process for the fluorescent whitening of textile materials. 

Detergent composition for textile fibre materials

The present invention provides a detergent composition D comprising at least one compound of formula (1) together with at least one compound of formula (2) wherein all substituents have the meanings as defined in the claims; as well as a process using such detergent composition and mixtures comprising fluorescent whitening agents.

Detergent compositions

A process is provided for the production of compounds having the formula: ##STR1## in which R is hydrogen, C.sub.1 -C.sub.5 alkyl, cyano or halogen; M is hydrogen or a salt-forming colorless cation; and n is 2;
