Abstract
This invention relates to an improvement in the art of making high pressure laminated materials utilizing saturating kraft paper. More particularly, the invention relates to release sheets coated with an aqueous polymeric composition which makes the sheets useful in the production of heat and pressure consolidated laminated materials. Papers which are coated with these aqueous polymeric compositions exhibit excellent release properties which, when employed as release sheets, permit high pressure laminates to be easily separated.
