Abstract: Described herein are compositions useful for infusing color into nonwoven polyester containing product and methods to do so. Such compositions and methods comprise use of a color infusion composition comprising an antimigrant polymer; pigment; ammonium polyphosphate; and an anionic surfactant comprising phosphate. In certain embodiments, thermoplastic polymer having a glass transition temperature (Tg) of 93.0° C. or less is used to enhance color infusion.
