Treatment for substrates.

摘要

A water-soluble or water-dispersible material for deposition onto a substrate during a treatment process, the material comprising:(i) a deposition enhancing part having a polymeric backbone; and(ii) a benefit agent attached to the deposition enhancing part by a hydrolytically stable bond;The material undergoes during the treatment process, a chemical change which does not involve the hydrolytically stable bond and by which change the affinity of the material onto the substrate is increased.
