Leuco polymers as bluing agents in laundry care compositions

A leuco polymer comprising a polyamine covalently bound to a leuco moiety and a red mono-azo dye moiety, wherein the polyamine is a polyalkylamine and a plurality of amine groups in the polyalkylamine are alkoxylated with polyalkylene oxide chains having from 5 to 30 alkoxy groups, wherein the alkoxy groups are selected from the group consisting of ethoxy and propoxy, wherein the leuco moiety has a maximum molar extinction coefficient in the wavelength range from 400 to 750 nm of 10 M−1 cm−1 or less, wherein the leuco moiety is a univalent or polyvalent moiety derived by removal of one or more hydrogen atoms from a structure of Formula (I)

• wherein the ratio of Formula (I) to its oxidized form is at least 1:3;
• wherein each individual Ro, Rm and Rp group on each of rings A, B and C is independently selected from the group consisting of hydrogen, deuterium and R5;
• wherein each R5 is independently selected from the group consisting of halogens, nitro, alkyl, substituted alkyl, aryl, substituted aryl, alkaryl, substituted alkaryl, —C(O)R1, —C(O)OR1, —C(O)O−, —C(O)NR1R2, —OC(O)R1, —OC(O)OR1, —OC(O)NR1R2, —S(O)2R1, —S(O)2OR1, —S(O)2O—, —S(O)2NR1R2, —NR1C(O)R2, —NR1C(O)OR2, —NR1C(O)SR2, —NR1C(O)NR2R3, —OR1, —NR1R2, —P(O)2R1, —P(O)(OR1)2, —P(O)(OR1)O−, and —P(O)(O−)2;
• wherein at least one of the Ro and Rm groups on at least one of the three rings A, B or C is hydrogen;
• each Rp is independently selected from hydrogen, —OR1 and —NR1R2;
• wherein G is hydrogen;
• wherein R1, R2 and R3 are independently selected from the group consisting of hydrogen, alkyl, substituted alkyl, aryl, substituted aryl, alkaryl, substituted alkaryl, and R4;
• R4 is a organic group composed of one or more organic monomers with said monomer molecular weights ranging from 28 to 500;
• and
• wherein any charge present in the leuco moiety is balanced with a suitable independently selected internal or external counterion.
