This application describes laundry care compositions that contain leuco colorants and their use in the laundering of textile articles. These types of colorants are provided in a stable, substantially colorless state and then may be transformed to an intense colored state upon exposure to certain physical or chemical changes such as, for example, exposure to oxygen, ion addition, exposure to light, and the like. The laundry care compositions containing the leuco colorants are designed to enhance the apparent or visually perceived whiteness of, or to impart a desired hue to, textile articles washed or otherwise treated with the laundry care composition.

A leuco composition comprises at least one leuco compound, the leuco compound comprising a leuco moiety and a polyalkyleneoxy moiety covalently bound to the leuco moiety. The polyalkyleneoxy moiety comprises at least one ethylene oxide group and at least one propylene oxide group. A laundry care composition comprises (a) at least one laundry care ingredient and (b) a leuco composition as described above. A method of treating a textile includes the steps of (a) providing such a laundry care composition; (b) adding the laundry care composition to a liquid medium; (c) placing textile articles in the liquid medium; (d) optionally, rinsing the textile; and (e) drying the textile articles.

The present invention relates to the unexpected discovery of novel multi-aromatic, multi-substituted compounds. In certain embodiments, the compounds of the invention are generated by condensing at least two phenolic- and/or aniline-containing monomers and an aromatic, aliphatic or heteroaromatic aldehyde- and/or ketone-containing monomer. In other embodiments, at least one monomer is isolated from a bio-based resource. In yet other embodiments, the compounds of the invention are bis- or poly-phenolic compounds.

Provided are methods for labeling target molecules, such as nucleic acids, with fluorescent dye compounds having the formula ##STR00001##
One method embodiment includes contacting reactive group Z of the fluorescent dye compound with the target molecule such that reactive group Z reacts with the target molecule to form a covalent bond between the group and the target molecule. Another method embodiment includes contacting a fluorescent dye compound that further includes a first member of a binding pair, with a target molecule that includes a second member of the binding pair. Also provided are target molecules labeled with the fluorescent dye compounds.
