Abstract
Abstract A decorated molded article is produced by preparing an assembly including a molding composition comprising a cellulose filler, a surface sheet of unpigmented paper, and an underlying sheet of paper, both of said sheets and the cellulose filler being impregnated-with 1 1/2 to 3 times their weight of thermosetting melamine-formaldehyde resin. A decorated sheet of a dense, filled paper unimpregnated with resin is interposed between the surface sheet and the underlying sheet, and the assembly is consolidated under heat and pressure to bond it into a decorated article of excellent quality.
