Beschreibung
Zusammenfassung:	A method of obtaining a laundry care composition, the method comprising the steps of (a) reacting a reactive leuco compound with a polymer to form a leuco polymer and (b) mixing the leuco polymer with at least one laundry care ingredient. The reactive leuco compound comprises at least one leuco moiety and at least one nucleophilic group. The polymer comprises at least one group capable of reacting with said nucleophilic group. The leuco moiety has a maximum molar extinction coefficient at a wavelength in the range 400 to 750 nm of less than 1000 M−1 cm−1.
