The first object is to use a one-pack type material as a base adjustment coating material to improve workability at the time of coating. Second, it has sufficient elasticity not only at normal temperature but also at low temperature. A third object is to form a coating film, and thirdly, to finish by applying a wide variety of overcoating materials. (A) A multilayer emulsion containing at least two layers of a core part and a shell part, the core part having an epoxy group and the shell part having a carboxyl group, and having a glass transition temperature of -30 to 30 ° C. , (B) a reactive compound capable of reacting with the component (a), and (c) an inorganic powder having an average particle diameter of 0.1 to 100 µm, wherein the pigment has a pigment volume concentration of 40 to 70%. And a base adjustment coating material having an elongation percentage at 20 ° C. of 120% or more and an elongation percentage at −10 ° C. of 20% or more. [Selection diagram] None |
