Abstract
A resin composition is produced by a method including a step of rapidly freezing a latex containing fine polymer particles (A), a step of thawing the latex which has been frozen in the preceding step, a step of mixing, into the latex which has been subjected to the preceding step, a resin (B) having a specific viscosity, and after the preceding steps, a step of separating the latex into a resin composition and a water component. The resin composition is an agglutinate containing the fine polymer particles (A) and the resin (B).
