Claims
- 1. Composite resin particles each of which comprises a granular body portion of crosslinked polymer having a mean diameter of 0.01 to 10.mu. and a number of linear non-crosslinked acrylic polymer chains, a part of the respective polymer chain penetrating into the inside of said granular body portion and the remaining part extending outwardly therefrom, thereby forming a semi-interpenetrating polymer network having no distinct interface between the granular body portion and the polymer chain portion.
- 2. The composite resin particles according to claim 1 wherein the granular body portion is composed of a crosslinked polymer selected from the group consisting of polyester resin, amino resin and other polycondensation resins, acrylic resin and other addition polymerization resins.
- 3. A method for preparing composite resin particles according to claim 1 wherein an acrylic compound is subjected to a solution polymerization in the presence of crosslinked polymer particles having a mean diameter of 0.01 to 10.mu..
- 4. A resinous composition for coating use comprising composite resin particles according to claim 1 dispersed in an organic solvent.
- 5. The composition according to claim 4 wherein the organic solvent is selected from the group consisting of an aromatic hydrocarbon, aliphatic hydrocarbon, alcohol, ether ketone and ester.
