(57) Abstract: (Corrected) PROBLEM TO BE SOLVED: To provide an aqueous coating composition in which solids, particularly pigments, are appropriately dispersed by a suitable dispersing agent. A hydrophilic polyether chain is included and 1. Maximum isocyanate group content of 0% by weight and 30-80% by weight A water-soluble polyisocyanate addition product having an ethylene oxide content (molecular weight 44) of 4 as a dispersant, which is an aqueous composition containing dispersed solids, the polyisocyanate addition product comprising: A) a polyisocyanate component; B) from one or more monohydric polyether alcohols having a molecular weight of 150 to 5000 and an ethylene oxide content of 50 to 99.5% by weight, C) one or more monohydric alcohols having a molecular weight of 32 to 5000, D) from tertiary amines. A reaction product of an amine component comprising: and E) one or more compounds having a molecular weight of 32 to 3000 and at least two isocyanate-reactive groups to form a urethane group and optionally a urea group. |
