Title:
POLYMER COMPOSITION, AQUEOUS DISPERSION PREPARED BY USING THE SAME AS EMULSIFIER, AND WATER-BASE COATING COMPOSITION
Document Type and Number:
WIPO Patent Application WO/1991/009895
Kind Code:
A1
Abstract:
The invention provides a polymer composition prepared by dispersing a urethane oligomer, prepared by the reaction of a hydroxyl-terminated diol compound having a molecular weight of 100 to 5.000, a diisocyanate compound, a compound having at least one active hydrogen atom and an amphoteric ion group in its molecule, and an ethylenically unsatured monomer having an active hydrogen atom in its molecule under an isocyanate-rich condition, in an aqueous medium containing a polyamine; an aqueous dispersion prepared by polymerising a monomer with the use of said composition as an emulsifier; and a water-base coating composition containing said dispersion. The polymer composition has a high emulsification stability, while the coating composition exhibits excellent coating performances especially when used as a metallic coating.
