Latex, resin composition, and method for producing same

Provided is a latex which has little environmental burden, has excellent dispersibility of polymer microparticles, and is useful in a novel technique, said latex being capable of efficiently recovering polymer microparticles from the latex. The present invention relates to a latex containing specific amounts of polymer microparticles (A) and a resin (B), the polymer microparticles (A) having a graft portion containing a polymer containing a specific structural unit, the resin (B) having a predetermined viscosity, and the surface of the polymer microparticles (A) being coated with the resin (B). 本发明提供环境负担小、聚合物微粒的分散性优异、且能够从胶乳中高效地回收聚合物微粒的在新技术中有用的胶乳。具体涉及一种胶乳，其包含特定量的聚合物微粒(A)和树脂(B)，其中，上述聚合物微粒(A)具有包含含有特定结构单元的聚合物的接枝部，上述树脂(B)具有给定的粘度，上述聚合物微粒(A)被上述树脂(B)包覆了表面。
