Abstract
A sheet material finished on at least one side with a coherent surface layer is formed by electrostatically spraying a solution or dispersion of plastics producing fibers from 0.1 to 30 microns in diameter. Then the mat is consolidated with heat and pressure, whereby the fibers form a tight bond with the surface of the support material which is thus finished.
