Patent number: 9527264Abstract: A backer sheet comprising a natural fiber and impregnated with a water-based acrylate resin is thermofused with a wood cellulose sheet impregnated with the same or different water-based acrylate resin to provide a continuous laminate. The acrylate resin diffuses into the pores of the natural fiber backer sheet and the wood cellulose sheet during impregnation. Heat and pressure are used to thermofuse the backer sheet and the wood cellulose sheet to form the laminate, and the sheets are permanently bonded after thermofusion. Advantageously, the thermofused laminate is free of volatile organic compounds and formaldehyde emissions. A topcoat or an iron oxide layer can be applied to the wood cellulose sheet after impregnating the wood cellulose sheet with the acrylate resin. A design can be transferred to the surface of the laminate or sheets using techniques such as dye sublimation or direct printing.Type: GrantFiled: March 26, 2014Date of Patent: December 27, 2016Inventors: Joseph Macedo, Millie Graves
