1. Fluoran compounds of the general formula (1) see diagramm : EP0095114,P11,F1 in which R1 and R2 independently of the other each denote a straight-chain or branched alkyl-C1 -C4 group or the benzyl group, R3 denotes a hydrogen atom or an alkyl-C1 -C4 , benzyl, acetyl, propionyl or benzoyl group, R4 and R5 independently of the other denote a straight-chain or branched alkyl-C1 -C4 group which can be substituted by fluorine, chlorine or bromine atoms or by hydroxyl, alkoxy-C1 -C4 or cyano groups, further a phenyl or benzyl group which can be substituted by fluorine, chlorine or bromine atoms or by alkyl-C1 -C4 , alkoxy-C1 -C4 , carb-(alkoxy-C1 -C4 ), optionally alkyl-C1 -C4 -substituted carboximado groups or cyano groups, and R4 and R5 together with the nitrogen atom can represent an optionally alkyl-C1 -C4 -subsituted piperidine, morpholine or indole radical, Y1 and Y2 independently of the other each represent a hydrogen, chlorine or bromine atom, an alkyl-C1 -C4 , alkoxy-C1 -C4 , alkoxy-C1 -C4 or phenyl group, B represents an optionally hydroxyl-, alkyl-C1 -C4 -or alkoxy-C1 -C4 -substituted alkylène-C2 -C6 group, and C denotes an optionally chlorine- or bromine-substituted 1,2-phenylene or 1,2-naphthylene radical. |
