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.
Claims12
A laundry detergent, comprising a cross-linked polymer obtainable by
- a) copolymerizing monomers of general formula (I) and general formula (II)
- in which R1, R2, and R3, independently of each other, are H or CH3, and n is a number in the range of from 1 to 90, preferably from 5 to 50,
- b) crosslinking the copolymer with a polythiol crosslinker and functionalizing with a compound of general formula (III),
- H2C═CH—R4—Z (III),
- in which R4 is an alkyl group with from 2 to 12 carbon atoms, and Z is a colorant compound, being linked by one of its N- or O-atoms to R4.
