Abstract
Abstract Composite resin particles each of which comprises a granular body portion of crosslinked polymer having a mean diameter of 0.01 to 10µ and a number of linear polymer chains, a part of the respective chain penetrating into the inside of the granular body portion and the remaining part extending outwardly therefrom. A dispersion of said composite resin particles in an organic solvent is useful as a resinous vehicle for coating compositions.
