Abstract
A decorative laminate is formed by placing an adhesive impregnated or coated decorative sheet on a core section, applying a polyester resin composition containing a peroxide catalyst and a photosensitizer to a release material and gelling the polyester resin composition by subjecting it to actinic light and placing the gelled polyester resin backed with release material on the impregnated or coated sheet supported by the core material and heat-pressing to form a composite structure. The release material is then removed from the cured polyester resin layer. Alternatively the polyester resin composition may be applied to the decorative sheet gelled with actinic light and then placed on the core sample, placing a release material on the gelled polyester resin composition and heat-pressing the composite. The resulting laminate is abrasion and stain resistant.
