The use of a thiazolium dye of formula for manufacturing a laundry care composition comprising the dye of formula and a laundry care ingredient: wherein: R 1 is branched or linear C 1-22 -alkyl, aromatic alkyl, polyalkylene oxide, or a moiety of Formula wherein R 2 is H, methyl, ethyl, propyl, acetate or hydroxyl; m and p each independently are integers of 0 to (n-1), with n being an integer of 1-6, and (m+p) = (n-1); and Y is hydroxyl, sulfonate, sulfate, carboxylate or acetate; R 3 and R 4 each independently are H; saturated or unsaturated C 1-22 -alkyl; hydroxy-C 2-22 -alkyl optionally comprising a further oxygen atom; a polyether moiety; amino-C 1-22 -alkyl; optionally substituted phenyl or benzyl; or C 1-22 -alkyl having a terminal sulfonate, sulfate, acetate, or carboxylate group; or R 3 and R 4 together form a saturated or unsaturated hetero- or carbocyclic moiety substituted by sulfate, sulfonate, phosphate, nitrate or carboxylate; R 5 and R 6 each independently are H, saturated or unsaturated C 1-22 -alkyl; hydroxy-C 2-22 -alkyl optionally comprising a further oxygen atom; a capped or uncapped polyether moiety; amino-C 1-22 -alkyl; optionally substituted phenyl or benzyl; C 1-22 -alkyl having a terminal C 1-4 -alkyl ether, sulfonate, sulfate, acetate, or carboxylate group; or thiazole; or R 5 and R 6 together form a thiazole moiety or a saturated or unsaturated heterocyclic moiety optionally substituted by at least one of alkoxylate, sulfate, sulfonate, phosphate, nitrate and carboxylate; or when taken together with R 7 and/or R 8 form one or more saturated or unsaturated heterocyclic moieties, optionally substituted by one or more of alkoxylate, sulfate, sulfonate, phosphate, nitrate, and carboxylate; R 7 and R 8, in addition to the above, each independently can be H or saturated or unsaturated alkyl; Q θ is an anion balancing the overall charge of the compound of Formula V; and q is 0 or 1.
