The present invention relates to new compounds which are useful as ultraviolet absorbing agents (UVAs) and to a method of improving the sun protection factor (SPF) of textile fibre material treated with the new compounds.
A compound having the formula:
in which m is 1 or 2; A is a residue selecte from those having the formulae:
or
B is -O-, -NH- or -SO₂-; and
D is a group having one of the formulae:
CH₂CH₂-OSO₃M in which M is hydrogen, sodium, potassium, calcium, magnesium, ammonium, mono-, di-, tri- or tetra-C₁-C₄alkylammonium or ammonium that is di- or tri-substituted by a mixture of C₁-C₄alkyl and C₁-C₄hydroxyalkyl groups, or, when A is a residue of formula (5) or (6), D may also be a group of formula:
in which B and M have their previous significance and n is 0 or 1, provided that at least one SO₃M group is present, or the formula:
