Abstract
Abstract A compounded and plasticized vinyl chloride polymer layer, optionally supported such as with a fabric, contains an outer adherent and stain resistant layer having durability and flexibility comprising the crosslinked reaction product of a reactive polyester having free carboxylic acid groups and an alkylated benzoguanamine-, urea- or melamine-formaldehyde resin. The vinyl chloride layer may be printed or embossed or both printed and embossed, optionally printed again, before the outer layer is applied.
