DEFINITION

Classification: 427/469

Coating material consists of charged particles (e.g., paint, pigment, dye, etc.):

(under subclass 466) Processes wherein the nonuniform coating

is formed by deposition of charged particles to a substrate by utilization of electrostatic charge, field, or force to form a non-imaged coating on the base.

(1) Note. The charged particles may be loose, free falling or suspended in a fluid for deposition thereof.
