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 obtained by the reaction of (a) a basic polycondensate with (b) an electrophilic dye of formula (2) P&#x2014;X&#x2014;YAn; wherein the basic polycondensate (a) is obtained by the reaction of (a) an amine of formula (I) in the presence of an anhydrous solvent with an ammonium salt (a) with a cyanamide: Wherein P, X, Y, a+, a, a, a, An, R, R, R, R, R, Rand A are defined in the claims and in the disclosure. The present invention also relates to compositions comprising these polymeric dyes, to a process for their use for dyeing of organic materials, such as keratin fibers, wool, leather, silk, cellulose or polyamides.

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

The invention relates to novel bis(triazinylamino)stilbenes which are suitable as UV absorbers and fluorescent whiteners for textile materials and also bring about an increase in the treated textile material.

Optical brighteners

Disclosed is a fabric rinse composition comprising a) 0.1 to 10% by weight of a UV absorber of formula (1), wherein A is a radical of formula (1a); B is a radical of formula (1c); (1d); (1e); (1f), (1g); (1b); (1i); (1k); (1l); or (1m); R, R, R, R, Rand Rare each independently of the others hydrogen, C&#x2013;Calkyl; C&#x2013;C-cycloalkyl; halogen; Ris hydrogen C&#x2013;Chydroxyalkyl; or C&#x2013;Ccycloalkyl; R, Rand Rare each independently of the others hydrogen, C&#x2013;Calkyl, C&#x2013;Ccycloalkyl, C&#x2013;Chydroxyalkyl; X is halogen; a radical of formula (1s); or (1u); sulfate, phosphate, lactate, citrate, tartrate; Ris C&#x2013;Calkyl; C&#x2013;Ccycloalkyl or phenyl: x is from 0 to 10; and y is from 1 to 20; b) 5 to 25% by weight, based on the total weight of the composition of a fabric softener agent; and c) the remainder being substantially water

Use of triazine-based UVAs for use as quenchers in paper-making processes

The use of liposomogenic UV absorbers for protecting human hair from the damaging effect of UV radiation is described. The liposomogenic UV absorbers comprise a hydrophilic head group (=Z), a spacer (=W), a UV chromophore (Q) having an absorption in the range from 285 to 400 nm and at least one hydrophobic tail group (=A). They have the formula ##STR1## in which A.sub.1 and A.sub.2 independently of one another are a hydrophobic radical;

Liposomogenic UV absorbers

The present invention relates to new compounds which are useful as ultraviolet absorbing agents (UVAs) and as fluorescent whitening agents (FWAs), and to a method of improving the sun protection factor (SPF) of textile fiber material, especially cotton, polyamide and wool, treated with the new compounds and with certain known compounds.

Method for increasing the SPF rating of textile fibers by treatment with

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;

Process for preparing distyrylbiphenyl compounds

The present invention relates to new compounds which are useful as ultraviolet absorbing agents (UVAs) and as fluorescent whitening agents (FWAs), and to a method of improving the sun protection factor (SPF) of textile fibre material, especially cotton, polyamide and wool, treated with the new compounds and with certain known compounds.
