irregular shape apparently causes sllear forces which disturb the flow and effect the uniformity of the distribution of metallic pigment in the thermoplastic. The end result is that the molding has streaks and presents a non-uniform appearance. On the other hand, in a simple or plain extrusion, a uniform finish can be ob-tained because the flow of plastic during the extrusion is relatively smooth and undisturbed resulting in a consistent and uniform distribution of the pigment in the thermoplastic. However, a plain extrusion will not provide a molding having the irregular shape required of a functional molding.
Wherefore, it is an object of the present invention to provide a decorative molding having an irregular cross section and yet presenting a surface having a uniform, colored, metallic appearance.

jl/'-~- -2a-DESCRIPTION OF THE INVENl'ION
.
The ~nolding of this invention serves a decoratlve function by presen~ing a colored me~allic appearance which can be ~rther enhanced~ as sh~wn in both embodirnents illustrated in the drawing, with a bright chrome-like strip ~long a portion the~eof~
~n addition, the molding also serves to protect the edge to which it ls attached and when used around an automobile window can act as a drip guide to prevent water from flowing down and into the win-dowO The molding is particularly adapted or use as a decorative and f~mctional molding for framing the rear portion of a quarter wLndow of an automobile and the disclosure of the present inven-tion is cast in terms appropriate for this contemplated use of the present invention. E~ovvever, it will be readily apparent to those skilled in the art that the molding of this irlvention can be advan-tageously applied to other parts of automobiles or to vans or other supporting structures such as appliances.
Nour x eferring to Figure 1, a molding of the present invention, generally indicated by numeral 1, has a curved top and sides and includes an elongated body 2 having an irregular CrosB
section. Elongated body 2 is characterized by channel 6, notch 7, and cavity 4 defined by inrler surEace 8 of lip 10 ànd bottom 12 of body 2. The structure of body 2 is thus characterized by a relatively complex cross section such as is suitable to bond-onto, and be retained by, a flange for example as can be found around a quarter window of a conventional automobile. Of course, it will be apparent to those ski'lled in ~e a1rt that-othe~esign3 having relatively complex cross sectit>ns are u~ithin the broad scope OI the preseSlt inven~ionO
L~aminated onto top surfa~e area 14 of bod,g 2 i~
ther~noplastic layer 16. Thermoplastic layer 16 contains naked metallic pigment 29 which imparts color and a metallic appearance theretoO Thu3, thermoplastic layer 16 has an appearance substantially the same as metallic paint on an automobile body. Laminated onto top surface area '15 of body 2 Is a decorative sandw;ch of a plastic film layer 18 which has a bright, reflective decorativP layer 19 there-on. Suitable layers 18 and 19 are provided by metallized plastic film ,, such as a ~netalli~ed polyester film, for example Mylar~)film avail-able from the duPont Company. Covering and protecting decorative layer 19 is a clear layer 22 oî vinyl or other suitable transparent material. Edges 24 and 26 of clear layer 22 are imbedded in thermo-plastic layer 16 and body 2 respectively. It will be appreciated by those skilled in the art that materiails vrhich can be used ~or decorative layer 19 are subject to discoloration if exposed to weather elements.
Slnce'edges 28 and 30 of layers 18 and 19 lie underneath clear layer 22, they are protected from exposure to the elements and decorative layer 19 is protected from resulting deteriorationO It is, ~f course, contemplated that the ends oî the elongated molding 1 will also be pro-tected or sealed against the elements to protect decorative layer 19 b~ -covering each end with a proteotive material as by end-capping or end-dipping each end~
Optimally~ and not sho~vn in the :Figure~ an additional acrylic layer can bP coated onto the clear vinyl layer to afford protection against deterioration of decorati~re layer 19 due tD ~ltra~
violet radiationO Also~ of course~ it will be apparent to those skilled in the art that other Iayers such as metal foil ~o~ld be substituted for plastic film layer 18 and decorative la~er 1~.
In accordance with the method of the present in~rention body 2 and thermoplastic layer 16 are both made by separately but conventionally extruding suitable thermoplastic materials~ Then thermoplastic layer 16 is laminated onto body 20 This could be done, for example, bg simultaneously extruding both body 2 and thermo-plastic layer 16 through separate dies and then immediately pressing them together by passing between rollers to laminate one to the other or by co-e~truding the body 2 and thermoplastic layer 16 through a co-extrusion die, In order to provide a molding having suitable flexibility and strength it has been found that body 2 can he made of polyvinyl chloride having a durometer hardness of about 80 shore A
to 60 shore D, Oî course, body 2 is made by extruding through a die having the desired irregular cross section~
Since body 2 is not exposed to view when in use, there is no need to color the extrusion or to be concerned about streaking should a pigrnent-conta.ning material be extruded. It is an advantage of the present invention that body 2 can be made of lower quality, less expensive material becarlse it is protected by thermoplastic layer 16 and plastic film layer 18 having decorative layer 19 and clear layer 22 thereon. ~c-r example, lnhibitors conventionally used to prevent deterioration ~ a molding ~vhen exposed to ultraviolet light are not necessary in body 2 ~ince body 2 is not exposed to such lightD
Thermoplastic layer 16, on the other hand, 1~
characterized by co~taining a flaked, met~llic pigment of a klnd and in an amount sufficien~ to impart the desired color and metallic appearance thereto. As can be seen in the drawing, thermoplastic layer 16 is a relatively thin layer of flaked, ~netallic pigment-con-tainlng thermoplastic material and can be conventionall~ extruded through a simple die wlthout incurring streaking problems. 111ermo-plastic layer 16 preEerably has a thickness of from about 0,1 to about 0. 5 millimeters, Plastic film layer 18 and decorative layer i9 ar~
laminated onto body 2 in a conventtonal manner, For example, If metaliized mylar is employed, the metallized mylar and body 2 c~n be passed between rollers, with heat, k~ effect lamination.
Now referring to Figure 2, another embodiment of a molding of the preseut invention Is generally indicated by the numeral 320 In this embodiment, thermoplastic layer 3~ containing flaked metallic pigment 36 is laminated to top surface 3~ of elongated body ~0 which is characterized by a complex cross section. Molding 32.
like molding 1 of Figure 1, is adapted to be bonded onto and be retained by a flange, for example, as can be found around the rear quarter win-dow of a conventional automobileO
A portion of thermoplastic layer 34, generally indicated at 42, has a ridge 44 laminated thereon. Similarly to the eml)odiment of Figure 1, laminated to top surface 46 of ridge 44 is a decorative sandwich of a plastic film layer 48 having a reflective, decorative surface SO tliereon. Covering and protec$ing decorative surface 50 is clear layer 52 of ~inyl or other suitable transparent material. Clear layer 52 extends beyond and protects edges 54 and 56 of the decorative surface 50 from exposure to the elements and resulting deterioration. It is, of course, contemplated that the ends of elongated molding 32 will also be protected or sealed against the elements as by end-capping or end-dippingO
As in the method of making the embodiment shown in lFigure 1, the method of making molding 32 involves conventionally laminating a separately but conventionally extruded, or co extruded, elongated `oody 40 and a thermoplastic, pigment-containing layer 34.
~idge 44 is bonded to thermoplastic, pigment-containing layer 34 ~nd elongated body 40 by means of a suitable adhesive or by other conventional means as by heating until the materials bond to each other. Preferably ridge 44 is made of a relatively harder material than body 40 so that ridge 44 provides structural strength to the molding and a good foundation for plastic film layer 48 and re~lective, decorative surface 50 while the use of softer material for body 40 minimizes ost and contributes to the flexibility of the molding. Plastic film layer 48 and reflective decorative surface SO, of course, are laminated to ridge 44 in the same , .
manner as in the previous embo~iment. Ridge 44 can be made by conventionally extruding a thermoplastic materiaL
While a preïerred embodiment of the present invention has been described and illustrated above, it is to be understood that the invention may be varied within the scope of the appeDded claims without departing irGm the spirit of the invention.

Preferably ridge 44 is made of a relatively harder material than body 40 so that ridge 44 provides structural strength to the molding and a good foundation for plastic film layer 48 and re~lective, decorative surface 50 while the use of softer material for body 40 minimizes ost and contributes to the flexibility of the molding. Plastic film layer 48 and reflective decorative surface SO, of course, are laminated to ridge 44 in the same , .
manner as in the previous embo~iment. Ridge 44 can be made by conventionally extruding a thermoplastic materiaL
While a preïerred embodiment of the present invention has been described and illustrated above, it is to be understood that the invention may be varied within the scope of the appeDded claims without departing irGm the spirit of the invention.
