The present invention relates to compounds having formula (1): wherein each R1 represents, independently, a linear C1-C4-alkylene residue which is unsubstituted or substituted by hydroxy, C1-C4-alkyl, C1-C4-alkoxy, C1-C4- hydroxy- or alkoxy-alkoxy, -OCOM, -OCOC1-C4-alkyl, or an amino acid residue from which a hydrogen atom on the amino group has been removed; each R2 represents, independently, a linear C1-C4-alkylene residue which is unsubstituted or substituted by hydroxy, C1-C4-alkyl, C1-C4-alkoxy, C1-C4- hydroxy- or alkoxy-alkoxy, -OCOM, -OCOC1-C4-alkyl, -CO2M, CO2C1-C4-alkyl SO3M or phenoxy which is unsubstituted or substituted by halogen, C1-C4-alkyl or C1- C4-alkoxy, -CO2M or CO2C1-C4-alkyl, NH2 or mono- or disubstituted amino; or phenyl which is unsubstituted or substituted by 1 to 3 SO3M, SO2NHC1-C4-alkyl, -SO2NH2, -CO2M, -CO2C1-C4-alkyl, -CONH2, -CONHC1-C4-alkyl, -NHCOC1-C4-alkyl or mono- or disubstituted amino groups; each R3 represents independently, hydrogen, C1-C4-alkyl, halogen, cyano, SO3M, -SO2NH2, SO2NHC1-C4-alkyl, -CO2M, -CO2C1-C4-alkyl, -CONH2, -CONHC1-C4-alkyl, or -NHCOC1-C4-alkyl; M is hydrogen, an alkali metal atom, ammonium or a cation formed from an amine and m is an integer of 1 to 3, a process for their preparation and use of the compounds as optical brightening agents for synthetic or natural organic materials or for removing stain in photographic materials.
L'invention concerne des composés de formule (1). Dans cette formule, chaque R¿1 ?est, indépendamment, un résidu alkylène C¿1?-C¿4? linéaire non substitué ou substitué par hydroxy, alkyle C¿1?-C¿4?, alcoxy C¿1?-C¿4?, hydroxy C¿1?-C¿4? ou alcoxy-alcoxy, -OCOMC¿1?-C¿4? alkyle, ou un résidu d'acide aminé dont on a éliminé un atome d'hydrogène sur le groupe amino; chaque R¿2? est, indépendamment, un résidu alkylène C¿1?-C¿4? linéaire non substitué ou substitué par hydroxy, alkyle C¿1?-C¿4?, alcoxy C¿1?-C¿4?, hydroxy C¿1?-C¿4? ou alcoxy-alcoxy, -OCOM, -OCOMC¿1?-C¿4? alkyle, -CO¿2?M, CO¿2?C¿1?-C¿4?-alkyle SO¿3?M ou phenoxy non substitué ou substitué par halogène, alkyle C¿1?-C¿4?, alcoxy C¿1?-C¿4?, -CO¿2?M, CO¿2?C¿1?-C4-alkyle, NH¿2? ou amino mono- ou disubstitué; ou phényle non substitué ou substitué par 1 à 3 SO¿3?M, SO¿2?NHC¿1?-C¿4?-alkyle, -SO¿2?NH¿2?, -CO¿2?M, -CO¿2?C¿1?-C¿4?-alkyle, -CONH¿2?, -CONHC¿1?-C¿4?-alkyle, -NHCOC¿1?-C¿4?-alkyle ou amino mono- ou disubstituté; chaque R¿3? est indépendamment, hydrogène, alkyle C¿1?-C¿4?, halogène, cyano, SO¿3?M, -SO¿2?NH¿2?, SO¿2?NHC¿1?-C¿4?-alkyle, -CO¿2?M, -CO¿2?C¿1?-C¿4?-alkyle, -CONH¿2?, -CONHC¿1?-C¿4?-alkyle, ou NHCOC¿1?-C¿4?-alkyle; M est hydrogène, un atome de métal alcalin, ammonium ou un cation issu d'une amine, et m est un entier valant de 1 à 3. L'invention concerne également un procédé relatif à l'élaboration de ces composés et à leur utilisation comme agents éclaircissants pour des matériaux organiques synthétiques ou naturels ou pour l'élimination de tâches sur des matériaux photographiques.
