ABSTRACT:
Process for coating tacky surface areas of an object, e.g., polymer surfaces making tacky areas by irradiation, commprising bringing particulate coating material, e.g., pigments, metals, etc., into contact with the tacky surface areas, and removing excess particulate coating material particularly from non-tacky areas, the particulate coating material being compressed beyond its bulk density by continuous vibration for at least a part of the time the particulate coating material is in contact with the surface to be coated. The process is useful in the preparation of color TV screens, electrical circuits, etc.
