Resilient surface coverings having improved scratch and stain resistance are disclosed in which a first top layer of a thermally-cured composition of a polyol component, an aminoplast component and an acid catalyst is adhered to a crosslinked or crosslinkable second layer material. A process to prepare such surface coverings is also disclosed.
