Title: Polymer emulsion and process for producing the same

Abstract: The present invention provides a polymer emulsion which contains polymer particles having an average particle size of not more than 30 .mu.m and having core-parts and shell-parts; which is composed of chitosan (a) and a polymer (b) of organic acids having a reactive vinyl group or a salt thereof, as constituent component of shell-part, and composed of a polymer (c) of hydrophobic monomers, as constituent component of core-part. Further, the present invention provides a coloring agent particle comprising a polymer particle in the above-mentioned polymer emulsion; and wherein a coloring material (k) is present in the shell-part and/or core-part. Furthermore, the present invention provides a deodorizing fiber wherein a polymer particle in the above-mentioned polymer emulsion is present on the surface of the fiber.
