  • Light stabilizer emulsion composition and aqueous coating agent composition containing the same
    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.

  • Antistatic composition
    Patent number: 7629401
    Abstract: The present invention provides an antistatic composition including: a polymer (A) containing a monomer unit represented by the following general formula (1): where R1 represents a hydrocarbon group having a benzene ring, A represents a methyl group or an ethyl group, and a plurality of A's may be the same or different from each other, m and n, each of which is an average polymerization degree of an oxyalkylene group, each represent a numeral of 1 or more, and p represents a numeral of 2 or more; and a low-molecular-weight anionic compound (B).
