Claim:
A. composition for sealing a colorant that is applied to a polyester fiber carpet, the composition comprising: a film forming polyurethane dispersion including (i) a first film forming polyurethane dispersion and (ii) a second film forming polyurethane dispersion, wherein the film forming polymyethane dispersion forms a film when applied to the polyester fiber carpet, and the film, upon drying, forms a topcoat on the polyester fiber carpet, wherein the first film forming polyurethane dispersion forms a hard component of the topcoat, and wherein the second film forming polyurethane dispersion forms a soft component of the topcoat; and a solvent for coalescing particles of a carpet colorant and causing the particles to flow into carpet fibers when composition is applied to the polyester fiber carpet, wherein, when the composition is dried on a portion of the polyester fiber carpet, to which the carpet colorant is applied, the composition seals and protects the portion of the polyester fiber carpet to which the colorant is applied such that, after the polyester fiber carpet is walked on by 30,000 steps and vacuumed by 600 strokes, the ΔE CMC (1:c=2:1) of the portion of the polyester fiber carpet to which the colorant is applied is less than about 6.0, and the ΔC CMC of the portion of the polyester fiber carpet to which the colorant is less than about −3.0 D, and wherein the composition is formulated as an aerosol spray.
