Abstract
The present invention provides a laundry treatment composition comprising an anionic dye-polymer.
Claims22
A laundry detergent composition comprising from 2 to 70 wt % of a surfactant together with from 0.0001 to 50 wt % of a blue or violet dye-polymer of molecular weight of at least 500, wherein the dye-polymer is obtainable by polymerisation of:
- (a) a dye monomer, the dye monomer an alkene covalently bound to a dye, the dye covalently bound to a group selected from:
- SO3− and CO2−, the dye monomer having a molar extinction coefficient at a wavelength in the range 400 to 700 nm of at least 1000 mol−1 L cm−1, and
- (b) one or more further alkene comonomer(s), the alkene monomer(s) having molar extinction coefficient at a wavelength in the range 400 to 700 nm that is less than 100 mol−1 L cm−1.
A dye-monomer, wherein the dye-monomer is selected from:
