The present invention provides new stilbene compounds which are useful as fluorescent whitening agents (FWAs), imparting high whiteness levels to textile fibre material treated with them, and which also impart a high sun protection factor (SPF) to textile fibre material treated with them. The present invention also concerns a method of imparting a high whiteness level and a high sun protection factor to textile fibre material, especially cotton, polyamide and wool, comprising treating the textile material with the new compounds.

Stilbene compounds and their use

The present invention provides a compound having the formula: ##STR1## in which each R.sub.d is the same or different and each is --NH--Z--N(R.sub.a)(R.sub.b) or --N--�Z--N(R.sub.a)(R.sub.b)!.sub.2 in which Z is C.sub.2 -C.sub.14 alkylene or optionally substituted arylene, R.sub.a and R.sub.b are the same or different and each is C.sub.1 -C.sub.12 alkyl, or R.sub.a and R.sub.b, together with the nitrogen atom to which they are each attached, form a morpholino, piperidino or piperazino ring; each R.sub.c is the same or different and is NH.sub.2, NH(C.sub.1 -C.sub.4 alkyl), N(C.sub.1 -C.sub.4 alkyl).sub.2, N(CH.sub.2 CH.sub.2 OH).sub.2, O--C.sub.1 -C.sub.4 alkyl, ##STR2## alkali metal atom, ammonium or a cation formed from an amine; or a quaternized form thereof. The present invention also relates to a composition for the treatment of textiles, in particular to a composition containing the new ultra-violet absorbing agents; and to a method for the improvement of both the sun protection factor (UPF) and the whiteness of textile fiber material, comprising treating the material with the composition according to the present invention.

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.
