Abstract:
A method of high speed coating a pigment-containing material onto a substrate so as to avoid visible pigment separation in the material in its as coated state, said method comprising:providing a first substrate having a coating surface to be coated; providing a pigment-containing liquid coating material; and applying the coating material to the surface of the first substrate along a substantially straight dynamic wetting line to form a coated layer having an interface surface in contact with the coating surface of the first substrate, while the first substrate is moving at a high line speed of at least about 50 ft./min. (15.24 m/min.), wherein the first substrate is removable from the coated layer and when the first substrate is removed from the coated layer, the coated layer exhibits no visible pigment separation on its interface surface.
