Dyeing OH- or amido-containing materials with reactive dyestuffs containing a difluoropyrimidine radical

In the dyeing or printing of a material of OH-- or synthetic amido-containing material using at least one reactive dyestuff, the improvement wherein said reactive dyestuff comprises a reactive dyestuff which, in the form of the free acid has the formula (I)

• in which
• A is a chromophoric radical of one of the following structures ##STR194## or a metal complex of dyestuffs of the formulae (8)-(11) ##STR195## in which the bond between the chromophoric radical A and the 4-pyrimidinyl radical is effected via an amino or aminomethyl function on a ring C atom and A,
• in which
• R denotes H, a C.sub.1 -C.sub.6 -alkyl radical, a C.sub.1 -C.sub.6 -alkoxy radical,
• R.sup.1 denotes H, CH.sub.3, C.sub.2 H.sub.5,
• R.sup.2 denotes NH.sub.2, a C.sub.1 -C.sub.4 -alkyl radical which is unsubstituted or substituted by OH, SO.sub.3 H, OSO.sub.3 H or CO.sub.2 H, a C.sub.1 -C.sub.4 -alkoxy radical which is unsubstituted or substituted by OH, SO.sub.3 H, OSO.sub.3 H or CO.sub.2 H,
• R.sup.3 denotes a C.sub.1 -C.sub.4 -alkyl radical which is unsubstituted or substituted by OH, SO.sub.3 H, OSO.sub.3 H or CO.sub.2 H, a phenyl radical which is unsubstituted or substituted by C.sub.1 -C.sub.4 -alkyl, halogen or SO.sub.3 H,
• D represents a sulpho- or carboxy-containing radical of a diazo component from the benzene, naphthalene or hetaryl series, which additionally may be substituted by alkyl, alkoxy, carboxyl or halogen radicals. In formula (6) one of the two radicals D contains an optionally substituted 2,6-difluoro-4-pyrimidinylamino, -methylamino or -ethylamino substituent, it being possible in this case for D to be free of sulpho groups or to contain sulpho groups.
• K represents a coupling component,
• with the exception of compounds 15 and 16 ##STR196## which are described by F. Lehr in Dyes+Pigments 14 (1990), 239-63.
