Abstract
A paper based overlay is provided. The overlay has a paper impregnated with a resin composition having an acrylic resin having a glass transition temperature in a range of from about −20° C. to about 40° C. and a resin content from about 15 to about 35 wt. % based on the weight of the overlay. The acrylic composition may include wax in the amount of about 0.005 to about 3.5 wt. % based on the weight of the resin composition. A method of producing the overlay is also provided. The overlay is highly water and abrasion resistant with low volatile content.
