acid radical and at least one reactive phosphoric or phosphonic acid
group

    • Azo dyestuffs of the formula: ##STR1## wherein A is a phenylene or naphthalene nucleus containing at least one phosphoric or phosphonic acid group; R.sub.1 and R.sub.2 are hydrogen or --SO.sub.3 H; and R.sub.3 -R.sub.6 are hydrogen, --SO.sub.3 H, or NR.sub.7 Q wherein R.sub.7 is hydrogen or lower alkyl and Q is hydrogen or an acyl group of 2 to 8 carbon atoms, at least two of R.sub.1 -R.sub.6 being --SO.sub.3 H and at least one being --NHQ, provided that when the dyestuff is monoazo, then Q is an acyl group of 3 to 8 carbons and when the dyestuff is disazo, Q is hydrogen or an acyl group of 2 to 8 carbon atoms. The dyestuff may be used to reactively dye cellulosic materials, e.g., cotton or cotton/polyester blends. The dyestuffs are particularly useful in dyeing mixed fabrics of cellulose and synthetics together with disperse dyes from a single bath.
    • 下式的偶氮染料:其中A是含有至少一个磷酸或膦酸基团的亚苯基或萘核; R1和R2是氢或-SO3H; 和R 3 -R 6是氢,-SO 3 H或NR 7 Q,其中R 7是氢或低级烷基,Q是氢或2至8个碳原子的酰基,R 1 -R 6中的至少两个是-SO 3 H,至少一个是 - NHQ,条件是当染料为单偶氮时,Q为3至8个碳的酰基,当染料为双偶氮时,Q为氢或2至8个碳原子的酰基。 染料可用于反应性地染色纤维素材料,例如棉或棉/聚酯混合物。 该染料特别适用于将纤维素和合成纤维的混合织物与来自单一浴液的分散染料一起染色。

    • Azo pyridone dyestuffs containing at least one reactive phosphoric or phosphonic acid group. The dyestuffs are characterized by the formula:A -- N .dbd. N -- Rwherein A is an aromatic radical containing at least one phosphoric or phosphonic acid group and R is a monovalent radical derived from a pyridone coupling component by removing a hydrogen atom attached to a ring carbon atom of the pyridone ring. The aromatic radical A is preferably a phenyl or naphthyl group. In addition to its phosphonic or phosphoric acid group or groups, radical A may be substituted with one or more halogen, alkyl, alkoxy, nitro, sulfonic acid or carboxylic acid groups. Cellulosic textiles, e.g., cotton or cotton/polyester blends, may be reactively dyed with these dyestuffs in an acid, neutral or alkaline bath using dicyandiamide or the equivalent. The phosphoric or phosphonic acid groups and the cellulosic material react to fix the dye through an ester linkage.Examples of suitable dyestuffs include those having the formula: ##STR1## and ##STR2##
    • 含有至少一个反应性磷酸或膦酸基的偶氮吡啶酮染料。 染料的特征在于下式:A-N = N-R其中A是含有至少一个磷酸或膦酸基团的芳族基团,R是衍生自吡啶酮偶联组分的一价基团,通过除去附着于 吡啶酮环的环碳原子。 芳基A优选为苯基或萘基。 除了其膦酸基或磷酸基团之外,基团A可以被一个或多个卤素,烷基,烷氧基,硝基,磺酸或羧酸基团取代。 纤维素纺织品,例如棉或棉/聚酯共混物,可以在酸,中性或碱性浴中用这些染料用双氰胺或其等同物反应染色。 磷酸或膦酸基团和纤维素材料通过酯键反应固定染料。 合适的染料的实例包括具有下式的那些:
