A pigment dispersing polymer comprising a backbone having one or more urea groups and having polymeric side chains extending therefrom. The dispersing polymer may be formed from the reaction of a compound having one or more carbodiimide groups with acid functional resins such as acid functional polyesters, acid functional acrylics, acid functional polyethers, and fatty acids.
La présente invention concerne un polymère de dispersion de pigment qui comprend un squelette ayant un ou plusieurs groupes urée à partir duquel s'étendent des chaînes latérales polymères. Le polymère de dispersion peut être formé par une réaction entre un composé ayant un ou plusieurs groupes carbodiimide et des résines fonctionnellement acides telles que des polyesters fonctionnellement acides, des acryliques fonctionnellement acides, des polyéthers fonctionnellement acides ou des acides gras.
