Abstract

1410815 Oxazines IMPERIAL CHEMICAL INDUSTRIES Ltd 1 Nov 1973 [20 Dec 1972] 58691/72 Heading C4P The invention comprises oxazine dyes free from sulphonic and carboxyilic acid groups having the general formula wherein R and R<SP>1</SP> are optionally substituted alkyl or aralkyl groups or R and R<SP>1</SP> together with the nitrogen atom form a heterocyclic ring, R<SP>2</SP> is optionally substituted alkyl, aralkyl or aryl or is a group -X-Y, R<SP>3</SP> is H or alkyl, X is an optionally substituted divalent alkylene group optionally interrupted with hetero atoms, Y is halogen and Z is an anion. They are prepared by nitrosating an amine of the general formula and reacting the nitroso compound formed with a meta-amino phenol of the general formula wherein R, R<SP>1</SP>-R<SP>3</SP>, X and Y are as above, the second stage preferably taking place after isolation of the nitroso compound and at pH 1-4À5: The dyes give greenish blue shades on poly. acrylonitrile and acid modified polyamides and polyesters.
