Claims
- 1. A surface layer comprising a (meth)acrylated polyester, the polyester being the reaction product of a diol and an aromatic tricarboxylic acid or anhydride, the diol being in excess of the aromatic tricarboxylic acid or anhydride on an equivalent basis and the reaction product of the diol and the acid or anhydride being (meth)acrylated, the surface layer having a stain resistance (sum of delta-E) of less than 100.
- 2. The surface covering of claim 1 wherein the diol is 1,6-hexanediol or 1,5-pentanediol.
- 3. The surface covering of claim 1 wherein the aromatic tricarboxylic acid or anhydride is trimellitic acid or anhydride.
- 4. The surface covering of claim 1 wherein the polyester comprises the reaction product of a diol and a first aromatic tricarboxylic acid or anhydride and a second aromatic polycarboxylic acid or anhydride which second aromatic polycarboxylic acid or anhydride is different from the first aromatic tricarboxylic acid or anhydride.
- 5. The surface covering of claim 4 wherein the first aromatic tricarboxylic acid or anhydride is trimellitic anhydride and the second aromatic polycarboxylic acid or anhydride is phthalic anhydride.
- 6. The surface covering of claim 1 wherein the polyester comprises the reaction product of a diol and an aromatic tricarboxylic acid or anhydride and a cycloaliphatic polycarboxylic acid or anhydride.
- 7. A surface layer comprising a blend of (1) a resin composition comprising a (meth)acrylated polyester, the polyester being the reaction product of a diol and an aromatic polycarboxylic acid or anhydride, the diol being in excess of the aromatic polycarboxylic acid or anhydride on an equivalent basis, the reaction product of the diol and the acid or anhydride being (meth)acrylated and (2) an ethoxylated triacrylate having the formula ##STR3## where n is 1 to 7.
- 8. The surface layer of claim 7 wherein the diol is 1,6-hexanediol or 1,5-pentanediol.
- 9. The surface layer of claim 6 wherein the surface layer is formed from a composition comprising less than 25% by weight of urethane.
- 10. The surface layer of claim 6 wherein the surface layer is formed from a composition which is substantially free of urethane moieties.
