Composition for sealing a colorant to a surface and/or for protecting a surface

A composition that prevents color change in 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 first film forming polyurethane dispersion and the second film forming dispersion are in a ratio of from about 1:1 to about 1:2, wherein the film forming polyurethane dispersion form 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 form 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 the composition is applied to the polyester fiber carpet,
• wherein, when the composition is dried on a portion of the polyester fiber carpet fiber, to which the carpet colorant is applied, the composition protects against color change in the portion of the polyester fiber carpet such that, after the polyester fiber carpet is walked on by 30,000 steps and vacuumed by 600 strokes, the ΔECMC (1:c=2:1) of the portion of the polyester fiber carpet is less than about 3.0, and the ΔCCMC of the portion of the polyester fiber carpet is less than about −2.0 D, and
• wherein the composition is formulated as an aerosol spray.

A composition for sealing and protecting a colorant that is applied to a polyester fiber carpet and for protecting 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 polyurethane dispersion is 12 wt. % or less of the composition, wherein the film forming polyurethane 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, 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 the composition is applied to the polyester fiber carpet,
• wherein, when the composition is dried on a portion of the polyester fiber carpet, to which colorant is applied, the composition seals and protects the portion of the polyester fiber carpet to which no colorant is applied such that, after the portion of the polyester fiber carpet is walked on by 30,000 steps and vacuumed by 600 strokes, the ΔECMC (1:c=2:1) of the no colorant portion of the polyester fiber carpet is less than about 3.0, and the ΔCCMC of the no colorant portion of the polyester fiber carpet is less than about −2.0 D,
• wherein, the composition seals the colorant to the polyester fiber carpet such that the ΔECMC (1:c=2:1) of the portion of the polyester fiber carpet to which the colorant is applied is less than about 1.55 after the portion of polyester fiber carpet to which the colorant is applied is vacuumed by 100 strokes.
