The present invention provides a compound having the formula: in which each Rd is the same or different and each is -NH-Z-N(Ra)(Rb) or -N-[Z-N(Ra)(Rb)]2 in which Z is C2-C14alkylene or optionally substituted arylene, Ra and Rb are the same or different and each is C1-C12alkyl, or Ra and Rb, together with the nitrogen atom to which they are each attached, form a morpholino, piperidino or piperazino ring; each Rc is the same or different and is NH2, NH(C1-C4alkyl), N(C1-C4alkyl)2, N(CH2CH2OH)2, O-C1-C4alkyl, 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. |
