Bis:amino-tri:phenyl:di:oxazinyl-amino S-triazine dyestuff cpds. - used for dyeing cellulosic material and leather in blue hue with good fastness

摘要

New 2,4-bis(10-amino-triphenodioxazin -3-yl-amino)-s-triazine dyestuffs are of formula (I); where R = H or (substd.) 1-4C alkyl; R' and X = H or a substit.; T1 and T2 = H, Cl, Br, (substd.) 1-4C alkyl, 1-4C alkoxy, phenyl or phenoxy; n = 0 or 1. Pref. R and R' = H; n = 1 and the SO3H gp. is in the o-position to the (substd.) amino gp.; T1 = T2 = Cl or OMe; X = halogen, SO3H, 1-4C alkyl or a thioether, ether or (substd.) amino gp. USE/ADVANTAGE - (I) are claimed for dyeing and printing cellulosic materials and leather. The pref. cellulosic materials are paper, cotton, and viscose. (I) give blue hues with good wet and light fastness, brilliance and clarity. They also combine well with other dyestuffs.
