Abstract
A multicolored thermoformed article is prepared by initially forming thermoplastic resin of a first color into a contoured design configuration. This preformed element is then placed in a thermoforming mold having an insert-receiving portion of complimentary contour and additional contours outwardly of the insert-receiving portion. Thermoplastic sheeting of a second color is then thermoformed against the surfaces of the mold and of the insert to produce the composite article in which the adjacent surface of the insert is thoroughly bonded to the sheeting of the second coloration. The process may be utilized to produce articles in which more than one preformed element is incorporated, and such multiple preformed elements may be of the same or distinct configurations and of the same or distinct colorations.
