[Conventional technology]

In recent years, non-aqueous dispersion paints have relatively little adverse effect on the environment due to the use of non-polar weak solvents, and because they are particles, they have a thixotropic viscosity behavior.
It has features such as easy thick coating, and it also has performance superior to conventional solvent-based paints and emulsion-type paints. in use. Under such circumstances, there is an increasing demand for higher performance non-aqueous dispersion paints, but no satisfactory paints have been obtained.

[Problems to be solved by the invention]

Thus, as far as the prior art is concerned, it is a reality that an extremely useful non-aqueous dispersion type paint which is excellent in both storage stability and various film properties cannot be obtained.

Therefore, the present inventors are aware of the current situation, drastically solve various unresolved problems in the prior art, and based on the urgent need of those skilled in the art, have excellent storage stability, and, We have been working diligently to obtain highly useful non-aqueous dispersion paints with excellent film performance.
