Abstract

1345146 Reactive dyestuffs IMPERIAL CHEMICAL INDUSTRIES Ltd 31 Aug 1971 [8 Sept 1970] 42964/70 Heading C4P The invention comprises reactive dyestuffs of the general formula wherein R is H or alkyl, DN(R)- is the radical of a water soluble dyestuff and R<SP>1</SP> is H or an alkyl, cycloalkyl, aralkyl or aryl group which may be substituted by substituents free from H atoms capable of reacting with cyanuric halides. D is preferably a radical of a mono- or dis-azo optionally metallized, dioxazine, nitro, azo-stibbene or phthalocyanine dye. They are prepared by (a) reacting 2 moles of a compound DNHR with a mole of a compound N,N-bis- (dichlorotriazinyl (-amino-R<SP>1</SP> where D 1 R and R<SP>1</SP> are as above or (b) diazotization and coupling wherein either the amine or coupling component contains a group of the formula and one mole of the amine or coupling component containing the above group is coupled with 2 moles of the other reactant. The dyes give yellow, orange, red, blue, scarlet, turquoise, brown and black shades on wool, nylon and especially cellulose.
