Leuco polymers as bluing agents in laundry care compositions

A laundry care composition comprising:

• (i) from 2 to 70 wt % of a surfactant;
• and
• (ii) from 0.0001 to 20.0 wt % of a leuco polymer comprising a polyamine covalently bound to a leuco moiety,
• wherein the polyamine is an alkoxylated polyethyleneimine comprising at least one ethoxylated group containing from 10 to 20 —CH2CH2O— repeating units,
• wherein the leuco compositon is a compound according to 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)O31, —C(O)NR1R2, —OC(O)R1, —OC(O)OR1, —OC(O)NR1R2, —S(O)2R1, —S(O)2OR1, —S(O)2O31, —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)O31, and —P(O)(O31)2;
• wherein all of the Ro and Rm groups on all three rings A, B or C are hydrogen;
• 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;
• wherein any charge present in any of the compounds is balanced with a suitable independently selected internal or external counterion.
