Abstract

A laundry care composition comprises a laundry care ingredient or adjunct and at least one compound that is capable of changing from a first color state (i.e., the initial color state in the composition) to a second color state that is perceptibly different from the first color state. A method for treating textile articles comprises the steps of: (a) providing a laundry care composition as described above; (b) adding the laundry care composition to a liquid medium; and (c) placing the textile articles in the liquid medium.

First claim

3. The laundry care composition of claim 1 , wherein the compound conforming to the structure of Formulae (I) comprises at least one R a group.

4. A method for treating textile articles, the method comprising the steps of:
(a) providing the laundry care composition of claim 1 ;
(b) adding the laundry care composition to a liquid medium; and
(c) placing the textile articles in the liquid medium.

5. The method of claim 4 , wherein the method is performed under conditions sufficient to convert the compound conforming to the structure of Formulae (I) from an unconjugated form represented by the structure to a conjugated form.
