Abstract:
Disclosed are surfactants represented by the following formula (1): wherein R represents a branched aliphatic hydrocarbon group, a secondary aliphatic hydrocarbon group or a branched aliphatic acyl group, AO and AO' each independently represents an oxyalkylene group having 2 to 4 carbon atoms, L represents a group represented by formula (2) to be described below, z stands for a number of from 1 to 10, X represents a hydrogen atom or an ionic hydrophilic group, m stands for a number of from 0 to 1,000, and n stands for a number of from 0 to 1,000. wherein R and R each independently represents a hydrogen atom or a methyl group, x stands for a number of from 0 to 12, and y stands for a number of 0 or 1. These surfactants do not contain any phenyl ether group considered to have significant effects on the environment, such as a nonylphenyl group, and have performance comparable with reactive surfactants containing one or more phenyl ether groups. Emulsifiers for emulsion polymerization, dispersants for dispersion polymerization and resin modifiers, all of which contain the surfactants, are also disclosed.

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.
