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): (Formule 1); in which M is hydrogen, an alkali metal atom, ammonium or a cation formed from an amine; R, and R,' independently of each other are -NH-R3, -N(R3)2 or -0-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 -0-R4 wherein R4 is hydroxy alkyl, alkoxy alkyl or hydroxy alkoxy alkyl, and R2' has the meaning of R1 or R2. L'invention concerne un procédé d'amélioration du facteur de protection solaire (SPF) de matières cellulosiques fibreuses et de mélanges de celles-ci. Ce procédé consiste à mettre en contact lesdites matières avec au moins un composé de formule (1): (Formule 1); dans laquelle M représente un hydrogène, un atome de métal alcalin, un ammonium ou un cation formé à partir d'une amine; R et R' désignent de manière indépendante -NH-R3, -N(R3)2 ou -0-R3, où R3 représente un aryle substitué par -CO-X-R5, où X désigne O ou NH et R5 représente un alkyle en C1-C4 éventuellement substitué, R2 représente un groupe de formule -0-R4, où R4 représente un hydroxy alkyle, un alcoxy alkyle ou un hydroxy alcoxy alkyle et R2 a la même signification que R1 ou R2.
