Abstract
Abstract An identity card, on which a printing area is to be electrostatically printed, consists of a two-layer paper laminate in which the adhesive layer joining the two layers is colored. The paper laminate is calendered and has a thickness of approximately 0.3 mm and a weight per unit area of approximately 300 g/m 2 . Both surfaces are provided with a pigment layer and a varnish made of a recticulated acrylate varnish, which each leave a printing area open.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
113 words
An identity card on a paper base having at least one printing area for electrostatically printing particulars of the card, comprised of at least a two-layer paper laminate having a colored adhesive layer jointing the layers of paper, the paper laminate being sealed by calendering to a specific volume V=d×1000/f of approximately one, in which d is the thickness in mm and f the weight per unit area of the paper laminate in g/m 2 , both surfaces of the card being provided with a strongly sized pigment layer which leaves the printing area open, and both surfaces of the card having a reticulated acrylate varnish coating which leaves the printing area open.
Claim 2
Dependent Claim
113 words
An identity card on a paper base having at least one printing area for electrostatically printing particulars of the card, comprised of at least a two-layer paper laminate having a colored adhesive layer jointing the layers of paper, the paper laminate being sealed by calendering to a specific volume V=d×1000/f of approximately one, in which d is the thickness in mm and f the weight per unit area of the paper laminate in g/m 2 , both surfaces of the card being provided with a strongly sized pigment layer which leaves the printing area open, and both surfaces of the card having a reticulated acrylate varnish coating which leaves the printing area open.
Claim 3
Dependent Claim
38 words
An identity card as defined in claim 1, in which, on the back of the card which faces the printing area a border around the varnish at the edge of the card is left at least partially open.
Claim 4
Dependent Claim
20 words
An identity card according to claim 1, in which the card carries printing between the sized pigment layer and varnish.
Claim 5

An identity card according to claim 4, in which the printing areas laterally coincide.
Claim 7
Dependent Claim
24 words

Claim 8
Dependent Claim
45 words
An identity card according to one of claims 1, 2, 3, or 6, further including a carrier strip coated with an adhesive substance to which the card sticks, the adhesive substance having an opening corresponding to the printing area on the back of the card.
Claim 9
Dependent Claim
47 words
An identity card according to one of claims 1, 2, 3, or 6, further including a carrier strip, to which the card is adherent, the adhesion thereof being weaker than that between the paper laminate and the pigment layer and between the pigment layer and the varnish.
Claim 10
Dependent Claim
27 words
An identity card according to one of claims 1, 2, 3, or 6, in which the pigment layer has a bonding agent formed of a latex dispersion.

Claim 15
Dependent Claim
41 words
An identity card according to claim 4, further including a carrier strip, to which the card is adherent, the adhesion thereof being weaker than that between the paper laminate and the pigment layer and between the pigment layer and the varnish.
Claim 16
Dependent Claim
21 words
An identity card according to claim 4, in which the pigment layer has a bonding agent formed of a latex dispersion.
Claim 17
Dependent Claim
