Abstract:
A method for increasing the SPF rating of a textile fibre material, comprising treating the textile fibre material with 0.05 to 3.0% by weight, based on the weight of the textile fibre material, of one or more compounds having the formula: ##STR22## in which M is hydrogen, an alkali metal atom, ammonium or a cation formed from an amine;R.sub.1 is a group having the formula: ##STR23## in which R.sub.3 is NR.sub.4 R.sub.5 in which R.sub.4 and R.sub.5, independently, are hydrogen, C.sub.1 -C.sub.4 alkyl, phenyl or benzyl or NH--CO--R.sub.6 in which R.sub.6 is C.sub.1 -C.sub.4 alkyl, cyclohexyl, phenyl or benzyl;or the formula: ##STR24## in which R.sub.6 has its previous significance; and R.sub.2 is NH.sub.2, N(CH.sub.2 CH.sub.2 OH).sub.2, N[CH.sub.2 CH(OH)CH.sub.3 ].sub.2, NH--C.sub.1 -C.sub.4 alkyl, NH-phenyl, ##STR25## O--C.sub.1 -C.sub.4 alkyl or O-phenyl, provided that the compound of formula (1) in which R.sub.1 is ##STR26## and R.sub.2 is ##STR27## is excluded.
