  • Detergent containing a photoactivated stain removal ingredient comprising a colorant-functionalized copolymer
    Patent number: 12441962
    Abstract: The present invention relates to laundry detergents which contain a cross-linked polymer obtained by a) copolymerizing monomers of general formula (I) and of general formula (II), and b) crosslinking the copolymer with a polythiol crosslinker and functionalizing with a compound of general formula (III). The present invention further relates to a process of laundering fabrics with the laundry detergent and irradiating with visible light. This shows improved attack on stains on fabric.
