Abstract
1,146,158. Imidazole dyes of the benzanthraquinone series. BADISCHE ANILIN- & SODA-FABRIK A.G. 7 July, 1966 [8 July, 1965], No.30550/66. Heading C4P. The invention comprises imidazole dyes of the formula wherein A represents a 1,4-phenylene or 1,3- phenylene radical which may bear halogen atoms or alkoxy groups. They may be obtained by reacting 1,2-diamino-3,4-benzanthraquinone with compounds of the formula X<SP>1</SP>-A-X<SP>2</SP>, wherein X<SP>1</SP> and X<SP>2</SP> each represent a -COOH, - COOR, -COY, -CHO, -CHY 2 or -CY 3 group, R is an alkyl, aralkyl or aryl radical and Y represents a halogen atom. The reaction may be carried out in a solvent or diluent in the presence or absence of agents, binding water and acids. Examples are given for the production of the dyes. They are useful for dyeing or printing materials derived from natural or regenerated cellulose or linear polyamides red to violet shades.
