Abstract
Initiator-treated pigment particles for use in making polymer coated pigment particles, are made up of a plurality of pigment particles. Each of the pigment particles has an outer surface that is covered with a coating of initiator material. The initiator material operates as a nucleus for initiating polymerization on the surface of the particle. The initiator-treated pigment particles are made by providing a plurality of pigment particles and applying a coating of initiator material to the outer surface of each pigment particle.

Initiator-treated pigment particles for use in manufacturing polymer-coated pigment particles, comprising:
- a plurality of pigment particles each having an outer surface which is covered with a coating of initiator material that operates as a nucleus for initiating polymerization on said surface of said particle.
A method of making initiator-treated pigment particles for use in manufacturing polymer-coated pigment particles, said method comprising the steps of:
- providing a plurality of pigment particles, each of said particles having an outer surface and
- applying a coating of initiator material to said outer surface of each of said plurality of pigment particles, said coating of initiator material operating as a nucleus for initiating polymerization on said surface of said particle.
A formulation for initiator-treated pigment particles that are used for manufacturing polymer-coated pigment particles, comprising:
- a solvent;
- a wetting agent for pigment;
- a polymerization initiator dissolved in said solvent;
- and
- a plurality of pigment particles dispersed in said solvent with the assistance of said wetting agent.
