Title:

A PROCESS FOR IMPROVING THE SUN PROTECTION FACTOR OF CELLULOSIC FIBRE MATERIAL

Document Type and Number:

WIPO Patent Application WO2001049924

Kind Code:

A3

Abstract:

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), whereby R1 represents hydrogen or C1-C4alkyl; R2 represents hydrogen, c1-c4alkyl, C1-C4alkoxy, halogen or SO3M, M being hydrogen or an alkali or alkaline earth metal; X1 is chlorine, fluorine, NR3R4, OR3 or SR3, wherein R3 represents hydrogen, C1-C4alkyl or C1-C4alkoxy, which are unsubstituted or substituted by one or more SO3M, OSO3M, COOM or OH groups, C2-C4hydroxyalkoxy, C1-C4alkoxy-C1-C4alkoxy or phenyl, which is unsubstituted or substituted by one or more SO3M, COOM, OH, halogen or C1-C4alkyl groups and R4 represents hydrogen, C1-C4alkyl, C2-C4hydroxyalkoxy, C1-C4alkoxoxy-C1-C4alkoxy or phenyl, or R3 and R4, together with the nitrogen atom, form a pyrrolidine, piperidine or morpholine ring; X2 is chlorine, when X1 is chlorine, or X2 is fluorine, when X1 is, NR3R4, OR3 or SR3 and Z is a fibre reactive group, whereby the cellulosic fibre material may also be treated with a fluorescent whitening agent either before, during or after contact with the compound of formula (1).
