Abstract:
Basic oxazine dyestuffs having the formula
WHEREIN R represents an alkyl group, R1, R2 and R3 each represent an alkyl group which may contain further substituents and R1 and R2 taken with one another and together with the nitrogen atom to which they are attached may form a heterocyclic ring, Alk represents an alkylene radical, X stands for a halogen atom or a cyano, trifluoromethyl, acyl or carboxylic acid ester group, or a carboxylic acid amide group which may be substituted, or an alkylsulfone or arylsulfone group, or a sulfonic acid amide group which may be substituted, or an acyloxy, acylamino, sulfonylamino, carbamic acid ester urea, or dicarboximido group, and A represents an anion.
