Abstract
A method for forming a layer of particles on a substrate, such as a layer of phosphor particles on the inside of a CRT, is described. The depends on the use of a double-sided adhesive tape comprising a laminate of a dry adhesive between two protective layers. One of the protective layers is stripped away to expose one surface of the dry adhesive layer which is then pressed up against the substrate surface using a method such as rolling or autoclaving to bring about bubble-free adhesion. The other protective layer is then stripped away, thereby exposing the other surface of the adhesive layer. The particles that will comprise the final layer are then applied to the exposed adhesive surface by means of dusting. This is followed by the removal of any weakly adhering particles from the final particle layer. Finally, the dry adhesive layer is itself removed by means of a heat treatment, leaving in place a uniform layer of particles adhering to the substrate surface.
