    Abstract: Basic oxazine dyestuffs of the formula I

    in which R stands for a lower alkyl group which may be substituted, R1 and R2 each stands for a hydrogen atom or a lower alkyl group which may be substituted and which may form together with the nitrogen atom also a heterocyclic radical, R3 stands for a hydrogen atom or a lower alkyl group which may be substituted, R4 stands for a hydrogen atom, a lower alkyl group which may be substituted, an aryl group which may be substituted, or together with the nitrogen atom and R3 or the benzene nucleus R4 may form a heterocyclic radical, and X stands for an anion, and the benzene nucleus a may carry further non ionic substituents or a fused benzene nucleus. The novel dyestuffs are suitable for the dyeing or printing of tannined cellulose fibers, silk, leather or fully synthetic fibers, such as acetate rayon, polyamide fibers or acid-modified polyamide or polyester fibers, especially of fibers containing polyacrylonitrile or polyvinylidene cyanide. The dyeings produced on these fibers are mostly very bright and have a good tinctorial strength as well as, in general, good fastness properties to light and wet processing, for example good fastness to washing, fulling, cross-dyeing, carbonizing, to the action of chlorine and to perspiration.
