  • Patent number: 7834084
    Abstract: An object of the present invention is to provide: a light stabilizer emulsion composition which has good long-term storage stability and does not deteriorate various physical properties of a coating film to be formed even when the composition is added to an aqueous coating agent composition; and an aqueous coating agent composition containing the light stabilizer emulsion composition. The light stabilizer emulsion composition of the present invention is characterized by containing: an emulsifier having as a hydrophilic group a polyether chain obtained by a reaction between two or more kinds of alkyleneoxides and having as a hydrophobic group a hydrocarbon group having 1 to 30 carbon atoms; at least one of a light stabilizer and a UV absorber; and water. Further, the aqueous coating agent composition of the present invention is characterized by containing the light stabilizer emulsion composition.

  • Patent number: 7799859
    Abstract: A surfactant composition has good emulsifiability for monomer(s), and can provide a polymer emulsion (herein after simply called “the emulsion”) of good stability while decreasing coagulations of polymer particles in the emulsion. The surfactant composition contains the following components (A) and (B): (A) a reactive surfactant containing at least one polymerizable double-bond group and at least one ionic group in a molecule, and (B) a nitrogen compound insoluble or slightly soluble in ethanol. A weight ratio (A:B) of the component (A) to the component (B) is from 100:0.03 to 100:1.0.
