Claim:
A multi-compartment pouch suitable for use in a laundry application comprising a water-soluble film and having at least a first and a second compartment smaller than the first compartment that is superposed over the first compartment, wherein the first compartment comprises a first composition and the second compartment comprises a second composition, characterised in that the second compartment comprises a whitening agent that exhibits a hueing efficiency of at least 5 and a wash removal value in the range of from about 30% to about 95%, as determined by the Method for Determination of Hueing Efficiency and Wash Removability, wherein said whitening agent comprises: (a) at least one chromophore component that comprises a thiophene colorant, and (b) at least one polymeric component; and wherein the whitening agent is characterized by the following structure: wherein R 1 and R 2 can independently be selected from: a) [(CH 2 CR′HO) x (CH 2 CR″HO) y H] wherein R′ is CH 3 , CH 2 —O—(CH 2 CH 2 O) z H; wherein R″ is selected from the group consisting of H, CH 2 O(CH 2 CH 2 O) z H, and mixtures thereof; wherein x+y≦5; wherein y≧1; and wherein z=0 to 5; b) R 1 =alkyl, aryl or aryl alkyl and R 2 =[(CH 2 CR′HO) x (CH 2 CR″HO) y H] wherein R′ CH 3 , CH 2 O(CH 2 CH 2 O) z H; wherein R″ is selected from the group consisting of H, CH 2 O(CH 2 CH 2 O) z H, and mixtures thereof; wherein x+y≦10; wherein y≧1; and wherein z=0 to 5 and; c) R 1 ═[CH 2 CH(OR 3 )CH 2 OR 4 ] and R 2 ═[CH 2 CH(OR 3 )CH 2 OR 4 ] wherein R 3 is selected from the group consisting of H, (CH 2 CH 2 O) z H, and mixtures thereof; and wherein z=0 to 10; wherein R 4 is selected from the group consisting of (C 1 -C 16 )alkyl, aryl groups, and mixtures thereof; with the proviso that z in a), b), or c) is not 0.
