Beschreibung
Zusammenfassung:	A process for improving the sun protection factor (SPF) of cellulosic fibre materials and blends thereof, which comprises contacting said materials with at least one compound of the formula (1), in which M is hydrogen, an alkali metal atom, ammonium or a cation formed from an amine; R1 and R1' independently of each other are -NH-R3, -N(R3)2 or -O-R3, wherein R3 is aryl substituted by -CO-X-R5, wherein X is O or NH and R5 is optionally substituted C1-C4-alkyl, R2 is a group of formula -O-R4 wherein R4 is hydroxy alkyl, alkoxy alkyl or hydroxy alkoxy alkyl, and R2' has the meaning of R1 or R2.
