摘要： The invention relates to latexes of hollow polymer particles which are coated with resins in order to improve the heat resistance and light scattering properties of the hollow polymer particles. The invention also relates to a method for coating synthetic hollow polymer particles with resins. The hollow polymer particle latex is coated with a formaldehyde based resin and the formaldehyde based resin comprises melamine, urea or combinations thereof.
