Abstract
A laundry additive article comprising an insoluble polymeric amine dye absorber physically adhered to an insoluble substrate is disclosed. The insoluble polymeric amine dye absorber is dye-selective, preferentially binding fugitive dyes in a wash solution, rather than detergent components or fabrics. The laundry additive article may comprise additional components including a dye transfer inhibitor and a signal to visually indicate that fugitive dyes have been scavenged.
