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.
L'invention concerne un matériau soluble dans l'eau ou dispersible dans l'eau prévu pour être déposé sur un substrat au cours d'un traitement. Le matériau comprend (i) une partie améliorant le dépôt comportant un squelette de polymère; et (ii) un agent promoteur fixé à la partie améliorant le dépôt par une liaison stable sur le plan hydrolytique. Pendant le traitement, le matériau subit une modification chimique qui ne met pas en jeu la liaison stable du point de vue hydrolytique et qui permet d'augmenter le changement d'affinité du matériau sur le substrat.
