AQUEOUS RESIN DISPERSION COMPOSITION

摘要

The present invention provides a resin aqueous dispersion composition comprising one or at least two resin particles and water, wherein when supposing that a primary average particle of each resin particle is substituted with a sphere having the same volume, a nonionic surfactant is present in an amount which occupies 75 to 95 % of the theoretical void among resin particles of 26 % when each resin particle is arranged in a close packed structure and the nonionic surfactant is a solvent which is substantially nonvolatile in a temperature range of up to 100 DEG C and evaporates or thermally decomposes at a temperature lower than the thermal decomposition temperature of the resin particles. The resin aqueous dispersion composition can be coated thickly and can prevent development of mud crack.
