at least one compound of the formula (I), in which:
R1 and R2 mutually independently denote hydrogen, a C1-C6 alkyl group, a C2-C6 alkenyl group, a hydroxyl group, a C1-C6 alkoxy group, halogen, an amino group, an acetylamino group, a nitro group, or a nitrile group, oralternatively, R1 and R2 form a 5- or 6-membered, saturated or unsaturated, carbocyclic or heterocyclic ring if R1 and R2 are in ortho position relative to one another;X denotes O or N—R3;R3 denotes hydrogen, a C1-C6 alkyl group, a C2-C6 alkenyl group, a C2-C6 hydroxyalkyl group, a C2-C6 polyhydroxyalkyl group, a C1-C6 cyanoalkyl group, an aryl-C1-C6-alkyl group, or a group —Y′—O—SO2—OM;Y and Y′, in each case, mutually independently denote (CH2)n, C2H4—(OC2H4)n, (CH2)n—O—(CH2)m, or (CH2)n—N(R8)-(CH2)m,
in which n and m in each case mutually independently denote an integer from 1 to 6,A denotes one of structures (II) to (XIII), in which:
R4 and R5, in each case, mutually independently denote hydrogen, a C1-C6 alkyl group, a C2-C6 alkenyl group, a hydroxyl group, a C1-C6 alkoxy group, halogen, an amino group, an acetylamino group, a C1-C6 alkylsulfonyl group, or a nitrile group, orR4 and R5 form a 5- or 6-membered, saturated or unsaturated, carbocyclic or heterocyclic ring if R4 and R5 are in ortho position relative to one another;R6 and R7 mutually independently denote a C1-C6 alkyl group, a C2-C6 alkenyl group, or a C2-C6 hydroxyalkyl group;R8 denotes hydrogen, a C1-C6 alkyl group, a C2-C6 alkenyl group, or a C2-C6 hydroxyalkyl group; andM denotes hydrogen, an alkali metal or half an equivalent of an alkaline earth metal. |
