[Subject] The present invention provides a coating material which has excellent properties such as chemical resistance, heat resistance, does not contain detrimental substances such as V O C, endocrine disrupting chemicals, etc. and further has excellent paintability. Furthermore, the present invention provides a container, which is coated with the coating material and has excellent properties. [Means for solving) The coating material of the present invention comprises a first aqueous dispersion (A) and a second aqueous dispersion (B) wherein a dispersoid of the first aqueous dispersion (A) has an average particle diameter of 1 to 20 µm and a dispersoid of the second aqueous dispersion (B) has an average particle diameter 1/100 to 1/5 of that of the dispersoid of the first aqueous dispersion (A), and the mass ratio (the aqueous dispersion (A) / the aqueous dispersion (B)) of the dispersoid of the first aqueous dispersion (A) to the dispersoid of the second aqueous dispersion (B) is 2/1 to 100/1.
L'invention porte sur un matériau de revêtement ayant d'excellentes caractéristiques telles que la résistance chimique et la résistance à la chaleur, qui ne contient pas de substances nuisibles telles que les composés organiques volatils (VOC) et les disrupteurs endocrines et présente une excellente aptitude de revêtement. L'invention porte également sur un contenant revêtu par le matériau de revêtement et ayant d'excellentes caractéristiques. Le matériau de revêtement contient une première dispersion aqueuse (A) et une seconde dispersion aqueuse (B). Le diamètre moyen de particule du dispersoïde de la dispersion aqueuse (A) est de 1 à 20 µm, et le diamètre moyen de particule du dispersoïde de la dispersion aqueuse (B) est de 1/100 à 1/5 du diamètre moyen de particule du dispersoïde de la dispersion aqueuse (A). Le rapport massique entre le dispersoïde de la dispersion aqueuse (A) et le dispersoïde de la dispersion aqueuse (B) (dispersion aqueuse (A)/dispersion aqueuse (B)) est de 2/1 à 100/1.
