An emulsion particle, an emulsion including the same, and a method of manufacturing an emulsion are provided. The emulsion particle includes: a core derived from a polymer of an unsaturated ethylenic monomer and including a first sub core and a second sub core surrounding the first sub core; and a shell surrounding the core and including an alkali-soluble resin, wherein the first sub core includes a polymer having a first glass transition temperature, and the second sub core includes a polymer having a second glass transition temperature lower than the first glass transition temperature.

Emulsion particle, emulsion comprising same, method for manufacturing emulsion

An emulsion, and a method of preparing an emulsion are provided. The emulsion includes styrene/acrylic latex particles and a metal stearate-based material.

Emulsion and preparing method therefor

The present invention provides a polymer emulsion having heat sealability for a blister package, and a method for preparing the same. Since the polymer emulsion of the present invention includes latex particles having an average particle diameter of a nanosize and a low unimodal particle size distribution, it may exhibit uniform and stable emulsion properties, particularly excellent heat sealability, and thus may be suitably used for a blister package and on the like. Furthermore, the polymer emulsion of the present invention is polymerized in an aqueous medium without using an organic solvent, and thus enables provision of a blister package with minimized harmfulness to a human body and the environment.
