Abstract
Abstract A monolithic laminate identification card which contains at least two layers (26, 27) with different optical permeability or color. The adjoining joinable surfaces of these layers are provided with complementary, interlocking embossed and debossed formations (21, 22). Under transmitted light a sign or image corresponding to these embossed and debossed formations can be seen that has a different brightness or color from the rest of the card (25).

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
91 words
An identification card comprising: at least a first and second plastic layer having different optical properties and having embossed and debossed formations formed thereon, said embossed and debossed formations further comprising complementary, interlocking formations for forming mutually joinable surfaces of said at least first and second plastic layers such that said at least first and second plastic layers are joined to form a monolithic laminate forming an image visible in transmitted light passed through said embossed and debossed formations, said image having different optical properties from the remainder of the card.
Claim 2
Dependent Claim
91 words
An identification card comprising: at least a first and second plastic layer having different optical properties and having embossed and debossed formations formed thereon, said embossed and debossed formations further comprising complementary, interlocking formations for forming mutually joinable surfaces of said at least first and second plastic layers such that said at least first and second plastic layers are joined to form a monolithic laminate forming an image visible in transmitted light passed through said embossed and debossed formations, said image having different optical properties from the remainder of the card.
Claim 3
Dependent Claim
46 words
The identification card according to claim 1, wherein the first plastic layer is a transparent plastic layer and the second plastic layer is a translucent plastic layer so as to form areas of different brightness and wherein said image further comprises said areas of different brightness.
Claim 4
Dependent Claim
29 words
The identification card according to claim 1, wherein said second plastic layer is a colored, translucent plastic layer and wherein said image further comprises areas of different color intensity.
Claim 5
Dependent Claim
31 words
The identification card according to claim 1, wherein an outer surface portion of each of said first and second plastic layers is provided with an abrasion-proof and mar-proof plastic foil coating.
Claim 6
Dependent Claim
30 words
The identification card according to claim 2, wherein the translucent plastic layer further includes a printed guilloche and/or directly readable information formed on an outer surface of said translucent layer.
Claim 7
Dependent Claim
59 words
The identification card according to claim 1, wherein the first plastic layer further comprises a translucent plastic layer and the second plastic layer further comprises a translucent plastic layer having a different light transmission characteristic than said first plastic layer so as to form areas of different brightness and wherein said image further comprises said areas of different brightness.
Claim 8
Dependent Claim
29 words
The identification card according to claim 1, wherein said second plastic layer further comprises a colored, translucent plastic layer and wherein said image further comprises areas of different colors.
Claim 9
Dependent Claim
35 words
The identification card according to claim 6, wherein the translucent plastic layer further comprises a printed guilloche and/or directly readable information formed on a surface of said second plastic layer adjacent said first plastic layer.
Claim 10
Dependent Claim
31 words
The identification card according to claim 2, wherein the translucent plastic layer further comprises a printed guilloche and/or directly readable information formed on an outer surface of said translucent plastic layer.
Claim 11
Dependent Claim
35 words
The identification card according to claim 7, wherein the translucent plastic layer further comprises a printed guilloche and/or directly readable information formed on a surface of said second plastic layer adjacent said first plastic layer.
Claim 12
Independent Claim
74 words
A method of manufacturing an identification card from first and second plastic layers, each having different optical properties and having guide means formed therein so as to form an image visible in transmitted light which comprises forming complementary, interlocking embossed and debossed formations on said first and second layers via said guide means and mounting said first plastic layer to said second plastic layer whereby an image is created by areas of different brightness.
