Abstract
A compounded and plasticized vinyl chloride polymer layer, optionally supported with a fabric, contains an outer adherent, stain resistant layer having durability and flexibility. The adherent, stain resistant layer is derived from a water-based polyester-amino resin composition. The stain resistant layer comprises the reaction product of said polyester, an acid catalyst, and an amino resin. The vinyl chloride layer may be printed or embossed or both printed and embossed, optionally printed again, before the outer layer is applied. A laminate formed from the polyvinyl chloride polymer layer and the stain resistant layer can also be embossed.
