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.

Abstract: 1339300 Basic oxazine dyestuffs FARBWERKE HOECHST AG 30 Dec 1971 [31 Dec 1970] 60721/71 Heading C4P Novel dyestuffs of the formula (wherein R is optionally substituted C 1-4 alkyl, R 1 and R 2 are each H or optionally substituted C 1-4 alkyl, or -NR 1 R 2 is a heterocyclic radical; R 3 is H or optionally substituted C 1-4 alkyl and R 4 is H or optionally substituted alkyl or aryl, or R 4 forms, together with the nitrogen atom and R 3 or the adjacent benzene nucleus and optionally via a further hetero atom, a heterocyclic radical; X (-) is an anion; and the benzene nucleus "a" may carry further non-ionic substituents or a fused-on benzene ring) are prepared by condensing (i) a 2-nitroso-5-NR 3 R 4 - phenol with a 2-NR 1 R 2 -hydroquinone di-(optionally substituted-alkyl) ether; or (ii) a 3-NR 3 R 4 -phenol with a 2-nitroso-5-NR 1 R 2 - hydroquinone di-(optionally substituted-alkyl) ether, both condensations being effected using salts of the starting materials which provide the anion X (-) and/or in the presence of a strong acid supplying the anion X (-) and, if desired, converting this anion in the product into another anion or replacing it by another anion. Also, products wherein R, R 1 , R 2 and X (-) are as defined above, R 3 is H or optionally substituted C 1-4 alkyl and R 4 is H or optionally substituted alkyl or aryl, but R 3 and R 4 cannot both be H, and ring a carries a fused-on benzene nucleus, are prepared by condensing a 2-nitroso-5- NR 1 R 2 -hydroquinone di-(optionally substitutedalkyl) ether with 2-hydroxynaphthalene in an acid medium supplying X (-) and then treating the resulting benz[a]phenoxazine with a primary or secondary amine NHR 3 R 4 . The dyestuffs are used for dyeing or printing tannined cellulose, silk, leather, acetate rayon, polyamide, acid-modified polyamide, polyester, polyacrylonitrile or polyvinylidene cyanide in shades varying from greenish blue through blue to reddish blue.
