Because of the slow dissolution rate of these photoactivators, step into water often problems, especially if the wash liquor is insufficiently mixed, because the colored photoactivators stain the laundry.

In EP-B-0 333 270 sind bereits feste Mikrokapseln von Phthalocyanin-Photoaktivatoren beschrieben, die mindestens 38 % eines Einkapselungsmaterials enthalten. Auch diese Mikrokapseln vermögen jedoch noch nicht, bezüglich Löseverhalten und Anschmutzung der Wäsche alle Wünsche der Verbraucher zu erfüllen.Solid microcapsules of phthalocyanine photoactivators are already in EP-B-0 333 270 described which contain at least 38% of an encapsulation material. This too However, microcapsules are not yet capable of dissolving and soiling the Linen to meet all consumer needs.

Es wurde nun gefunden, dass überraschenderweise Granulate, enthaltend eine wasserlösliche Phthalocyaninverbindung, einen anionischen Dispergator und maximal 25 Gew. % eines organischen Polymers, sich durch eine hohe Lösegeschwindigkeit in Wasser auszeichnen, so dass die vorstehend genannten Probleme weitgehend oder vollständig beseitigt sind. Ein weiterer Vorteil dieser Granulate ist, dass auch bei längerem Kontakt mit einem nichtionischen Tensid, die Phthalocyaninverbindung nicht aus dem Granulat herausgelöst und das Waschmittel nicht angefärbt wird.It has now been found that, surprisingly, granules containing a water-soluble Phthalocyanine compound, an anionic dispersant and a maximum of 25% by weight an organic polymer, characterized by a high dissolution rate in water distinguish, so that the above problems largely or completely are eliminated. Another advantage of these granules is that even with prolonged contact with a nonionic surfactant, the phthalocyanine compound does not come from the granules detached and the detergent is not stained.

Gegenstand der vorliegenden Erfindung sind somit wasserlösliche Granulate von Phthalocyaninverbindungen, enthaltend

  • a) 2 bis 50 Gew. % einer wasserlöslichen Phthalocyaninverbindung,
  • b) 10 bis 95 Gew. % eines anionischen Dispergators,
  • c) 0 bis 25 Gew. % eines wasserlöslichen organischen Polymers,
  • d) 0 bis 10 Gew. % eines weiteren Zusatzes und
  • e) 3 bis 15 Gew. % Wasser, bezogen auf das Gesamtgewicht des Granulates.
  • The present invention thus relates to water-soluble granules of phthalocyanine compounds containing
  • a) 2 to 50% by weight of a water-soluble phthalocyanine compound,
  • b) 10 to 95% by weight of an anionic dispersant,
  • c) 0 to 25% by weight of a water-soluble organic polymer,
  • d) 0 to 10% by weight of a further additive and
  • e) 3 to 15% by weight of water, based on the total weight of the granules.
  • Als Phthalocyaninverbindung kommen für die erfindungsgemässen Granulate Phthalocyaninkomplexe mit zwei-, drei- und vierwertigen Metallen (Komplexe mit einer d0 und d10 Konfiguration) als Zentralatom in Betracht. Es handelt sich vor allem um ein wasserlösliches Zn, Fe(II), Ca, Mg, Na, K, Al, Si(IV), P(V), Ti(IV), Ge(IV), Cr(VI), Ga(III), Zr(IV), In(III), Sn(IV) oder Hf(VI) Phthalocyanin, wobei Aluminium- und Zinkphthalocyanine besonders bevorzugt sind.Suitable phthalocyanine compounds for the granules according to the invention are phthalocyanine complexes with di-, tri- and tetravalent metals (complexes with ad 0 and d 10 configuration) as the central atom. It is primarily a water-soluble Zn, Fe (II), Ca, Mg, Na, K, Al, Si (IV), P (V), Ti (IV), Ge (IV), Cr (VI), Ga (III), Zr (IV), In (III), Sn (IV) or Hf (VI) phthalocyanine, with aluminum and zinc phthalocyanines being particularly preferred.

    and the phthalocyanine ring system can also contain further solubilizing groups.

    Die Zahl der Substituenten Q1 und Q2 in Formel (1a) bzw. (1b), die gleich oder verschieden sein können, liegt zwischen 1 und 8, wobei sie, wie bei Phthalocyaninen üblich, nicht eine ganze Zahl sein muss (Substitutionsgrad). Sind noch andere, nichtkationische Substituenten anwesend, so liegt die Summe aus letzteren und den kationischen Substituenten zwischen 1 und 4. Wieviele Substituenten im Molekül mindestens vorhanden sein müssen, richtet sich nach der Wasserlöslichkeit des resultierenden Moleküls. Eine ausreichende Wasserlöslichkeit ist dann gegeben, wenn genügend Phthalocyaninverbindung in Lösung geht, um auf der Faser eine photodynamisch katalysierte Oxidation zu bewirken. Es kann bereits eine Löslichkeit von 0,01 mg/l ausreichend sein, im allgemeinen ist eine solche von 0,001 bis 1 g/l zweckmässig. The number of substituents Q 1 and Q 2 in formula (1a) or (1b), which may be the same or different, is between 1 and 8, and, as is customary in the case of phthalocyanines, it does not have to be an integer (degree of substitution) , If other non-cationic substituents are also present, the sum of the latter and the cationic substituents is between 1 and 4. The minimum number of substituents that must be present in the molecule depends on the water solubility of the resulting molecule. Sufficient water solubility is given when enough phthalocyanine compound goes into solution to cause photodynamically catalyzed oxidation on the fiber. A solubility of 0.01 mg / l may already be sufficient, in general that of 0.001 to 1 g / l is appropriate.

    A- s in Formel (1a) bedeutet als Gegenion zur positiven Ladung des Restmoleküls ein beliebiges Anion. Im allgemeinen wird es durch den Herstellungsprozess (Quaternierung) eingeführt. Es bedeutet dann vorzugsweise ein Halogenion, ein Alkylsulfat- oder ein Arylsulfation. Von den Arylsulfationen seien das Phenylsulfonat , p-Tolylsulfonat- und das p-Chlorphenylsulfonation erwähnt. Als Anion kann aber auch jedes andere Anion fungieren, da die Anionen in bekannter Weise leicht ausgetauscht werden können; As - kann also auch ein Sulfat-, Sulfit-, Carbonat-, Phosphat-, Nitrat-, Acetat-, Oxalat-, Citrat-, Lactation oder ein anderes Anion einer organischen Carbonsäure darstellen. Der Index s ist bei einwertigen Anionen gleich r. Für mehrwertige Anionen nimmt r einen Wert ≤ r an, wobei er je nach Bedingungen so beschaffen sein muss, dass er die positive Ladung des Restmoteküls gerade kompensiert.A - s in formula (1a) means any anion as a counterion to the positive charge of the residual molecule. It is generally introduced through the manufacturing process (quaternization). It then preferably means a halogen ion, an alkyl sulfate or an aryl sulfate ion. Of the aryl sulfate ions, phenyl sulfonate, p-tolyl sulfonate and p-chlorophenyl sulfonate are mentioned. Any other anion can also act as the anion, since the anions can be easily exchanged in a known manner; A s - ie can also be a sulfate, sulfite, carbonate, phosphate, nitrate, acetate, oxalate, citrate, lactate ion or another anion represent an organic carboxylic acid. The index s is equal to r for monovalent anions. For polyvalent anions, r assumes a value ≤ r, whereby depending on the conditions it must be such that it just compensates for the positive charge of the residual moiety.

    Beispiele 35 bis 53: Die in der folgenden Tabelle aufgelisteten Formulierungen werden erhalten, indem man zunächst wässrige Lösungen der Komponenten herstellt und diese dann in einem Fluidized Spray Dryer granuliert. Examples 35 to 53 : The formulations listed in the following table are obtained by first preparing aqueous solutions of the components and then granulating them in a Fluidized Spray Dryer.

    Wie bereits im Beispiel 8 beschrieben, wird in der ersten Phase dieses Granulationsprozesses die Anlage als ein Sprühtrockner betrieben, um die für die Granulation erforderlichen Keime im Wirbelbett herzustellen (T zuluft=210°C, TBett=115°C). Sind genug Keime für die Granulation im Wirbelbett vorhanden, wird die Bettemperatur auf ca.65°C abgesenkt, um den Granulationsprozess einzuleiten. Die Granulation der Phthalocyaninlösungen erfolgt bei einer Wirbelbettemperatur von 60 - 68 °C. Das Granulat enthält am Austrag des Granulators ca. 12 Gew. % Restfeuchte und wird anschliessend in einem kontinuierlich arbeitenden Fliessbett, dem 85°C warme Luft zugeführt wird, auf den formulierungsspezifischen Sollwert (siehe nachstehende Tabelle) nachgetrocknet. Das Granulat ist unabhängig von der jeweiligen Formulierung frei fliessend, lässt sich rasch in Wasser lösen und ist visuell während Tagen unlöslich in nichtionischen Tensiden. Bsp. Nr.
