Abstract

Gegenstand der Erfindung ist ein Farbentwickler, der ein Hydroxylaminderivat der Formel (I) oder ein Salz dieses Derivats enthält:

Figure 80000001
wobei in dieser Formel bedeuten:

  • L: eine geradkettige oder verzweigte Alkylengruppe;
  • A: eine Carboxyl-, Sulfo-, Phosphono-, Hydroxyl-, Amino-, Ammonium-, Carbamoyl-, Sulfamoyl- oder Alkylsulfonylgruppe oder ein Phosphinsäurerest;
  • R: ein Wasserstoffatom oder eine Verbindung der Formel -L-A mit den oben angegebenen Bedeutungen für L und A;
    dadurch gekennzeichnet, daß dem Farbentwickler dieses Hydroxylaminderivat in Form der Reaktionslösung der zur Herstellung verwendeten Ausgangssubstanzen zugesetzt worden ist.
    • The invention relates to a color developer which contains a hydroxylamine derivative of the formula (I) or a salt of this derivative:
    Figure 80000001
    where in this formula mean:
  • L: a straight-chain or branched alkylene group;
  • A: a carboxyl, sulfo, phosphono, hydroxyl, amino, ammonium, carbamoyl, sulfamoyl or alkylsulfonyl group or a phosphinic acid residue;
  • R: a hydrogen atom or a compound of the formula -LA with the meanings given above for L and A;
    characterized in that this hydroxylamine derivative has been added to the color developer in the form of the reaction solution of the starting substances used for the preparation.

    • Der Einsatz des Hydroxylaminderivats in Form der ungereinigten Reaktionslösung ermöglicht eine einfachere und kostengünstigere Herstellung eines Farbentwicklers. Überraschenderweise wird durch diese ungereinigte Reaktionslösung Qualität und Funktion des Farbentwicklers nicht oder nur unwesentlich beeinträchtigt.The use of the hydroxylamine derivative in the form of the unpurified Reaction solution enables a simpler and less expensive Production of a color developer. Surprisingly is by this unpurified reaction solution quality and The function of the color developer is not affected or only slightly affected.
