ABSTRACT:
Polymer particles in a size range between 2 and 15 micrometers, and having a refractive index close to, but not identical with, that of a matrix polymer and optionally having one or more enclosing shells, the outer shell being compatible with the matrix polymer, impart light-diffusing properties to the matrix polymer without degrading its physical properties, while the particles having a closer refractive index match to the matrix polymer impart gloss reduction to the surface of the matrix polymer.
