Abstract

1479034 Cationic pyrazole dyestuffs PRODUITS CHIMIQUES UGINE KUHLMANN 7 Aug 1974 [8 Aug 1973] 34703/74 Heading C4P Novel dyestuffs of the formula (wherein R 1 is H, halogen or C 1-2 alkoxy; R 2 is H, halogen or NO 2 ; R 3 is C 1-5 alkyl; R 4 is H or phenyl optionally substituted by halogen, NO 2 or C 1-2 alkoxy; and X is a monovalent anion) are prepared by treating dyestuffs of the formula with an alkylating agent, these dyestuffs being in turn prepared by coupling an appropriate diazotized 5-aminopyrazole with an appropriate pyrazolone. The novel dyestuffs find use in the coloration in yellow shades of fibres based on polymers or copolymers of acrylonitrile or on polyesters or polyamides modified by acid groups.
