Abstract
Abstract Retroreflective material, and articles of manufacture made therefrom and process of making the same, wherein the color of an underlying colored material, such as colored thermoplastic film, is visible, in visible light, through the portion of an overlying substantially clear material, such as clear thermoplastic film, which clear material is sealed such as by heat sealing, to the colored material, the sealing obliterates or removes the retroreflective surface intermediate the materials at the place of sealing making the color of the underlying colored material visible through the sealed portion; the retroreflectivity of the remaining intermediate retroreflective surface is undiminished. Upon the entire periphery of the overlying and underlying layers of material being sealed, the remaining retroreflective surface intermediate the layers is completely sealed against contamination and the retroreflectivity of the remaining intermediate surface is undiminished.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
151 words
A retroreflective article of manufacture providing a colored decorative effect in visible light comprising, in combination, a set of adhesively joined layers comprising: a top layer of substantially transparent predetermined material; a retroreflective surface disposed beneath said top layer providing retroreflective effects; a lower opposed layer of colored predetermined material underlying the top layer; wherein said layers are heat sealed together adhesively, the materials forming the colored layer and the top layer causing the retroreflective effects of the retroreflective surface to be cancelled along the edges thus formed by the heat sealing, these edges lying along the periphery and in any desired location intermediate the peripheral edges, making said lower layer of colored predetermined material become visible through said sealed portion of said top layer providing a colored decorative effect in visible light which effectively cancels the retroreflective effects of the retroreflective surface along any edges formed by the heat sealing.
Claim 2
Dependent Claim
151 words
A retroreflective article of manufacture providing a colored decorative effect in visible light comprising, in combination, a set of adhesively joined layers comprising: a top layer of substantially transparent predetermined material; a retroreflective surface disposed beneath said top layer providing retroreflective effects; a lower opposed layer of colored predetermined material underlying the top layer; wherein said layers are heat sealed together adhesively, the materials forming the colored layer and the top layer causing the retroreflective effects of the retroreflective surface to be cancelled along the edges thus formed by the heat sealing, these edges lying along the periphery and in any desired location intermediate the peripheral edges, making said lower layer of colored predetermined material become visible through said sealed portion of said top layer providing a colored decorative effect in visible light which effectively cancels the retroreflective effects of the retroreflective surface along any edges formed by the heat sealing.
Claim 3
Dependent Claim
28 words
Article according to claim 1 wherein said lower opposed layer of colored thermoplastic material comprises substantially transparent heat seal adhesive and an underlying layer of colored plastic film.
Claim 4
Dependent Claim
28 words
Article according to claim 2 wherein said top layer and underlying layer of colored film are thermoplastic films heat sealed together through said substantially transparent heat seal adhesive.
Claim 5
Dependent Claim
34 words
Article according to claim 1 wherein said lower opposed layer of colored material is provided with a bottom surface covered with a layer of pressure sensitive adhesive covered by a layer of release material.
Claim 6
Dependent Claim
19 words
Article according to claim 1 wherein said lower opposed layer of colored predetermined material comprises colored heat seal adhesive.
Claim 7
Dependent Claim
23 words
Article according to claim 5 wherein said top and lower layers are thermoplastic films heat sealed together through said colored heat seal adhesive.
Claim 8
Dependent Claim
19 words
Article according to claim 1 wherein said retroreflective surface is provided on the lower surface of said top layer.
Claim 9
Dependent Claim
43 words
Article according to claim 1 wherein said lower opposed layer of colored predetermined material comprises substantially transparent heat seal adhesive and an underlying layer of colored plastic film and wherein said retroreflective surface is provided on the top surface of said colored film.
Claim 10
Dependent Claim
44 words
Article according to claim 1 wherein said lower opposed layer of colored predetermined material comprises colored heat seal adhesive and an underlying layer of plastic film and wherein said retroreflective surface is provided on the top surface of said underlying layer of plastic film.
