1. A water soluble pouch comprising:
a water soluble first sheet; a water soluble second sheet joined to said water soluble first sheet to at least partially define a chamber containing a substrate treatment agent; and an ink; wherein each of said first sheet and said second sheet have an interior surface and an opposing exterior surface; wherein said chamber is at least partially defined by said interior surface of said first sheet and said interior surface of said second sheet; and wherein said ink comprises a pigment selected from the group consisting of: diketopyrrolo-pyrrole of the general formula wherein each R can be the same or different and each R represents a cyano group, methyl or an alkyl group, a hydrogen group, a phenyl group, or a halogen group; quinacridone of the general formula anthraquinone of the general formula phthalocyanine pigment particles, comprising a phthalocyanine chromogen structure as a main component, and a substituted soluble metal-phthalocyanine dye as a minor component that non-covalently bonds with the phthalocyanine chromogen structure, molecules of the substituted soluble metal-phthalocyanine dye being intercalated between layers of the phthalocyanine chromogen structure, wherein the substituted soluble metal-phthalocyanine dye is of the general formula where: M is a metal or group of metals and atoms capable of bonding to a central cavity of the phthalocyanine molecule; and each R independently represents H or a sterically bulky substituent, provided that at least one R is other than hydrogen, and the sterically bulky substituent is a wax-like aliphatic group or an alkylaryl or arylalkyl group, where: the alkylaryl or arylalkyl group comprises a C═N or C═S double bond, or the alkylaryl or arylalkyl group is fully saturated consisting of a hydrocarbon group; coumarin of the general formula naphthalimide of the general formula and mixtures thereof; wherein said ink is between said substrate treatment agent and at least one of said interior surface of said first sheet and said interior surface of said second sheet. |
