A leuco polymer comprising an alkoxylated polyethyleneimine covalently bound to a leuco moiety, wherein at least a first portion of nitrogen atoms of the alkoxylated polyethyleneimine have covalently bound thereto a leuco moiety; at least a second portion of nitrogen atoms of the alkoxylated polyethyleneimine have covalently bound thereto a moiety selected from the group consisting of oxyalkylene moieties, polyoxyalkylene moieties, and mixtures thereof; and at least a third portion of nitrogen atoms of the alkoxylated polyethyleneimine have covalently bound thereto a moiety selected from the group consisting of an alkylene chain, an alkylene chain having covalently bound thereto a phenyl or naphthyl group, and mixtures thereof. Methods of making the leuco polymer, laundry care compositions comprising the leuco polymer and methods of treating textiles with such laundry care compositions.
New routes to 1-functionally substituted arylbenzotriazoles: 3-Benzotriazol-1-yl-pyridazine-4-ones, 5-benzotriazol-1-yl-pyridazine-6-ones and 5-benzotriazol-1-yl-pyridazine-6-imines
Condensation of 1-arylhydrazono-1-benzotriazol-1-yl 2-propanones (5a-c) with DMF DMA afforded 1-aryl-3-benzotriazol-1-yl-1,4-dihydropyridazine-4-ones (8a-c). While condensation of 1-functionallysubstituted methylbenzotriazoles 3b,c with 2-arylhydrazono-3-oxoarylpropanal 13a,b give 3-aroyl-5-(benzo-triazolyl-1-yl)-1,6-dihydro-1-phenylpyridazine-6-ones and 6-imines 14a-d.
