Leuco polymers as bluing agents in laundry care compositions

A composition comprising a first leuco polymer and a second leuco polymer,

• the first 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,
• the second 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;
• and 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,
• wherein a molar ratio of the second leuco polymer to the first leuco polymer in the composition is from 10:1 to 1:100.
