Abstract: In a process for the production of smooth surfaced parts, a paste material, which includes paste or granule pieces which are coated with added pigment and then pressed back together, is applied, in the form of an extrusion or a coating, to a substrate. The extrusion or coating is subjected to a first, incomplete hardening, after which it is no longer flows freely under its own weight. The surface layer, containing added pigment, is then removed from a surface to be used. This surface is subsequently smoothed, and the hardening of the coating to form a hard material is completed. The smoothing and the completion of the hardening can occur in the same processing step as a shaping for the formation of separable shaped parts. The substrate can be inseparable from the hardened coating. The surface layer, containing added pigment, can be removed by mechanical means, solvents or abrasion by a suspension in liquid or air, if appropriate in the presence of ultrasound.

Abstract: A decorative emblem is formed by insertion of a decorative foil shape into a preformed bezel and encapsulating and bonding the foil to the bezel with a fluent, curable plastic material. After an initial casting of a measured amount of plastic onto the base of the bezel, the foil is inserted and seated.

Upon curing, the plastic cap gives a lens effect to the decorative emblem. The emblem may be equipped with attachment means for fastening it to an automobile, appliance, or other object. In alternative embodiments, a decorative foil shape is placed directly onto the base of the bezel, and a fluent, curable plastic material is cast thereon. As the plastic material cures, it migrates around the edges and under the foil to at least partially encapsulate the foil and bond it within the bezel.

Abstract: Formation of an optical design pattern in an article of polyethylene terephthalate by utilizing the property of polyethylene terephthalate to become crystallized and whitened upon slow cooling and the fact that cooling of a plastic article molded within a mold advances from the surface portion of the article in contact with the surface of the mold toward the wall of the article. Based on this theory, a desired portion of the wall of an article of polyethylene terephthalate is whitened by properly controlling the degree and speed of cooling of the polyethylene terephthalate article in the mold to cool it slowly. The whitened portion in the wall is developed as an optical design pattern that can be viewed from outside. The whitened optical design pattern developed by the aforesaid technique can be made more distinct by heat treatment and stretching treatment.

Abstract: A contrasting color is imparted to the decorative surface of a decorative laminate by inserting a pigment coated release sheet between the molding caul and the decorative surface during the molding operation, with the pigment facing the decorative surface. Upon application of heat and pressure during the formation of the laminate, color is transferred from the release sheet to the decorative surface. A suitable technique is also used to emboss or impart surface texture to the decorative surface during molding. Thereafter, the textured surface is subjected to rubbing or brushing to remove more color from the embossed or raised areas than the debossed areas, thereby highlighting or imparting a shaded effect to the textured surface.
