Document Type and Number:
WIPO Patent Application WO/2006/013703
Kind Code:
A1
Abstract:
Disclosed is a light stabilizer emulsion composition having good long-term shelf life stability which can be added to an aqueous coating composition without causing deterioration in various physical properties of a coating film which is formed from the aqueous coating composition. Also disclosed is an aqueous coating composition containing such a light stabilizer emulsion composition. The light stabilizer emulsion composition is characterized by containing an emulsifier having a polyether chain obtained by reacting two or more kinds of alkylene oxides as a hydrophilic group and a hydrocarbon group having 1-30 atoms as a hydrophobic group; a light stabilizer and/or an ultraviolet absorbent; and water. The aqueous coating composition is characterized by containing such a light stabilizer emulsion composition.
