Abstract
1326776 Monoazo dyes FARBWERKE HOECHST AG 2 Dec 1970 [4 Dec 1969] 57363/70 Heading C4P The invention comprises water-soluble fibre reaction dyes having the formula wherein K represents the radical of a coupling component of the benzene, naphthalene, acetoacetic acid arylamide, pyrazolone or dihydroxyquinoline series which may contain one or more sulphonic acid and/or carboxylic acid groups; R is hydrogen, alkyl or aryl; n is 0 or 1 and X represents a group of the formula wherein R<SP>1</SP> is H or alkyl; R<SP>11</SP> is H, alkyl or phenyl and Y and Y<SP>1</SP> which may be the same or different each represents a fluorine or chlorine atom. The dyes may be prepared by diazotization and coupling. Alternatively the reactive cyclobutane carbonyl radical may be introduced by acylation of the required aminoazo compound. The dyes give orange, red, violet and yellow shades on leather, synthetic polyurethane, natural and synthetic polyamide and natural and regenerated cellulose fibres. Reference has been directed by the Comptroller of Specifications 1,089,993, 1,103,422, 1,103,423 and 1,123,804.
