    Abstract: Pyridone dyes useful for thermal transfer have the formula (I) where R1 is hydrogen or C1-C4-alkyl, R2 and R3 are identical or different and each is, independently of the other, hydrogen, substituted or unsubstituted C1-C12-alkyl, C5-C7-cycloalkyl, substituted or unsubstituted phenyl, substituted or unsubstituted pyridyl, substituted or unsubstituted C1-C12-alkanoyl, C1-C12-alkoxycarbonyl, substituted or unsubstituted C1-C12-alkylsulfonyl, C5-C7-cycloalkyl-sulfonyl, substituted or unsubstituted phenylsulfonyl, substituted or unsubstituted pyridylsulfonyl, substituted or unsubstituted benzoyl, pyridylcarbonyl or thienylcarbonyl or are together with the nitrogen atom to which they are bonded unsubstituted or C1-C4-alkyl-substituted succinimido, unsubstituted or C1-C4-alkyl-substituted phthalimido or a five- or six-membered saturated heterocyclic radical which may contain further hetero atoms, X is CH or nitrogen, Y is cyano or a radical of the formula CO-W, CO-OW or CO-NHW where W is hydrogen, C1-C8-alkyl which may be substituted and which may be interrupted by one or two oxygen atoms in ether function, C5-C7-cycloalkyl, phenyl or tolyl, and Z is an aromatic carbocyclic or heterocyclic radical.

    Abstract: New 1-amino-tetrahydropyrid-2,6-dione dyestuffs are of formula (I). In (I), R1 = H or 1-4C alkyl; R2 and R3 = H, 5-7C cycloalkyl, 1-12C alkoxycarbonyl, 5-7C cycloalkylsulphonyl, pyridyl, thienyl or a (substd.) 1-12C alkyl, phenyl, pyridyl, 1-12C alkanoyl, 1-12C alkylsulphonyl, phenylsulphonyl, pyridylsulphonyl or benzoyl gp.; or NR2R3 = opt. 1-4C alkyl-substd. succinimido, opt. 1-4 C alkyl-substd. phthalimido or a 5-6-membered satd. heterocyclic gp., opt. contg. other hetero-atoms; X = CH or N; Y = CN, CO-W, CO-OW or CO=NHW; W = H, 1-8C alkyl, which may be substd. and have 1 or 2 ether O atoms in the chain, 5-7 C cycloalkyl, phenyl or tolyl; Z = an aromatic carbocyclic or heterocyclic gp.

    Abstract: Bis(5-azo-6-hydroxy-4-methyl-3-hydroxysulphonyl-pyrid-2-on- 1-yl) dyes (I) of formula (A), in the form of free acids or their salts, are claimed. In A, A and Y are each -SO3H; Z is D-N=N-; D is the residue of a diazo component; and X is a 2-8 C alkylene opt. with an ether O atom in the chain. Also claimed are bis(6-hydroxy-4-methy-3-hydroxysulphonyl-pyrid-2-on-1-yl) cpds. (II) of formula (A), in which Y is -SO3H and Z is H, in the form of the free acids or salts, and the prepn. of (II).
