Abstract (en)

[origin: WO9600220A1] S-Triazinylaminostilbene derivatives of formula (1) are described in which Y is halogen, alkoxy or -NR<2>R<3> (where R<2> and R<3> are the same or different and are H, alkyl, hydroxyalkyl or aryl or together with the nitrogen atom form a substituted or unsubstituted cyclic amino group having 5-7 ring members), R is H, aryl, which is unsubstituted or substituted (e.g. by one or more electron releasing groups such as C1-4alkyl and/or C1-4alkoxy), R<1> is H or alkyl, Z is an electron-withdrawing group (e.g. CN, -SOxM), x is 2 or 3 and M is H, a metal cation or -N<+>R<4>R<5>R<6>R<7> (where R<4>-R<7> are the same or different and are H, alkyl, aralkyl or hydroxyalkyl). The compounds are useful as optical whitening agents for paper or textiles.
