Abstract:
Una composición fotoestabilizante en emulsión, que comprende: un emulsionante que tiene como un grupo hidrófilo una cadena de poliéter obtenida mediante una reacción entre dos o más tipos de alquilenóxidos y que tiene como un grupo hidrófobo un grupo hidrocarbonado que tiene de 1 a 30 átomos de carbono; al menos uno de un fotoestabilizante y un absorbente de radiación UV; y agua, en la que el contenido de al menos uno de un fotoestabilizante y un absorbente de radiación UV está dentro de un intervalo de 20 a 80% en masa.
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.
