Abstract
1402075 Diamino anthraquinone dyes FUJI PHOTO FILM CO Ltd 23 May 1973 [23 May 1972] 24749/73 Heading C4P [Also in Division C2] Blue anthraquinone dyes have the formula wherein R represents H, a st. or branched chain alkyl group (C 1 -C 20 ), cyclohexyl, aralkyl, or aryl, where an aromatic ring in an aralkyl or aryl group can be substituted by an alkyl group of 1 to 6 carbon atoms, an alkoxyl group, a carboxyl group, a nitro gp. or halogen atom. Thirteen 1,4 - bis - [2<SP>1</SP>,6<SP>1</SP> - dimethyl - 41- substituted anilino]-anthraquinones are exemplified, and the preparation of the intermediate 4-amino-3,5-xylenol derivatives (II) is also described. The dyes are formed by reaction of 1,4,9,10-tetrahydroxyanthracene with (II) in the presence of a dehydrating agent (boric acid or a boric acid ester of an alcohol), optionally in the presence of a high boiling solvent (b.p. 100-190‹ C.). They may be used for tinting polyester and polyamide products, including fibres, films and other polymer mouldings, and also for films used as the support of a photographic film.
