Abstract:
A method for forming a high gloss coating on a porous substrate comprising the steps of(a) forming a high gloss coating composition by blending a waterborne, crosslinkable polymer that is resistant to water penetration when dried and cured with a water dispersible film forming polymer of at least 5,000 molecular weight in an aqueous medium;(b) applying said high gloss coating composition onto a smooth non-porous surface of a carrier substrate so as to provide a uniform, pin hole free coating at a rate equal to or greater than 0.3 lbs per 1000 square feet of carrier surface;(c) partially or fully curing said coating; and(d) transferring the cured high gloss coating from the carrier to the surface of a porous sheet material so as to provide a coated sheet material with a gloss rating equal to or greater than about 50.
