ABSTRACT:
A non-slip mat, pad or coaster which is considerably thinner than present known and available pads, the mat or pad being formed from a thin plastic sheet having a lower surface with a tacky characteristic to provide a non-slip coefficient of friction; the mat or pad being formed from a suitable plastic material, such as polyvinyl, polyproplylene, polycarbonate, polystyrene or polyester, etc., and the lower surface is formed by coating the surface with a suitable ink, such as an ultraviolet ink, water-based ink or solvent-based ink containing a tackiness agent in the form of an acrylated polymer. The ink may be applied as a very thin firm of the ink adhesively joined to the underside of the plastic, or the ink is coated onto the undersurface of the pad or mat by silk screening, or in a multimaterial coating operation.
