A leuco polymer of the formula:

##STR00001##

Each of the G radicals is independently selected from the group consisting of:

##STR00002##

A is an arylene or heteroarylene, A.sup.1 is an aryl or heteroaryl, and B is a bridge member. R.sup.1 and R.sup.2 are independently selected from the group consisting of hydrogen and R.sup.4. R.sup.4 is independently selected from the group consisting of alkyl, cycloalkyl, aryl, alkoxy, amino, substituted alkyl, substituted cycloalkyl, substituted aryl, substituted alkoxy and substituted amino. X.sup.i is a charge balancing mono- or multi-valent counterion and i is an integer from 1 to 10.

A leuco composition comprises at least one reactive leuco compound, which reactive leuco compound comprises a leuco moiety and at least one reactive moiety covalently bound to the leuco moiety. A laundry care composition comprises a laundry care ingredient and a leuco composition. A method of treating a textile comprises the steps of (i) treating a textile with an aqueous solution containing a leuco composition, (ii) optionally, rinsing the textile, and (iii) drying the textile.

A leuco polymer includes a leuco monomer and an alkene. The leuco polymer has a molecular weight of at least 500 and is obtainable by polymerization of the leuco monomer and one or more alkene co-monomers. The leuco monomer consists of an alkene covalently bound to a leuco moiety and the leuco monomer has a molar extinction coefficient at a wavelength in the range 400 to 750nm of less than 1000 M.sup.1cm.sup.1. The alkene monomer(s) have a molar extinction coefficient at a wavelength in the range 400 to 750nm that is less than 100 M.sup.1cm.sup.1.
