Abstract
Abstract A gaming form such as a lottery ticket or the like, and a method for constructing the same, employ a biodegradable and recyclable paper substrate as the base, made from recycled fibers provided with carbon black for a high degree of opacity, and having biodegradable binders and coating layers made from water based coatings. The gaming form includes an opaque paper substrate which can be partly recycled fibers in a protein based binder, and defines the base of the form. The base, which is black, is coated with titanium oxide layers to resemble white paper. Indicia affecting the value of the form, for example indicia indicating winning status, is printed on the coating and covered with a non-concealing varnish protective layer, and by a water-based scratch-off coating, which also is environmentally safe. Successive layers of scratch-off coating and the inks applied to the form generally, are water based dispersions of resins, fillers, pigments and surfactants. A non-stick powder is applied as a last step.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
77 words
A gaming form comprising: an opaque paperboard substrate, including paper fibers mixed with a sufficient quantity of carbon black to render said paperboard substrate opaque, the carbon black being dispersed throughout said paper fibers; a pigment coating on the substrate for concealing the carbon black; indicia applied to and contrasting with said substrate; a non-concealing protective coating over said indicia; and, a removable coating concealing said indicia; whereby the gaming form is rendered secure without incorporating foil.
Claim 2
Dependent Claim
77 words
A gaming form comprising: an opaque paperboard substrate, including paper fibers mixed with a sufficient quantity of carbon black to render said paperboard substrate opaque, the carbon black being dispersed throughout said paper fibers; a pigment coating on the substrate for concealing the carbon black; indicia applied to and contrasting with said substrate; a non-concealing protective coating over said indicia; and, a removable coating concealing said indicia; whereby the gaming form is rendered secure without incorporating foil.
Claim 3
Dependent Claim
25 words
The gaming form according to claim 1, wherein the opaque paperboard substrate is made from about 80% recycled paper fibers and about 20% virgin fibers.
Claim 4
Dependent Claim
16 words
The gaming form according to claim 1, wherein the indicia is at least one printed character.
Claim 5
Dependent Claim
16 words
The gaming form according to claim 3, wherein said printed character is printed with carbon black.
Claim 6
Dependent Claim
16 words
The gaming form according to claim 3, wherein said printed character is printed with ink jet.
Claim 7
Dependent Claim
22 words
The gaming form according to claim 1, wherein the non-concealing coating covers at least an area of the substrate including said indicia.
Claim 8
Dependent Claim
23 words
The gaming form according to claim 1, wherein the removable coating covers at least an area of the substrate including said non-concealing coating.
Claim 9
Dependent Claim
18 words
The gaming form according to claim 7, said removable coating comprising water based acrylic resins, pigments and fillers.
Claim 10
Dependent Claim
18 words
The gaming form according to claim 1, further comprising a confusion pattern covering at least said removable coating.
Claim 11
Dependent Claim
21 words
The gaming form according to claim 1, further comprising anti-tack material disposed on at least an area of said removable coating.
Claim 12
Dependent Claim
14 words
The gaming form according to claim 10, wherein said anti-tack material comprises corn starch.
Claim 13
Independent Claim
113 words
A method for preparing a gaming form, comprising the steps of; forming an opaque paperboard substrate by mixing paper fibers with a sufficient quantity of carbon black during formation of the substrate to render said paperboard substrate opaque; applying a pigment coating to the substrate for concealing the carbon black and rendering the substrate similar in appearance to a plain paperboard substrate; printing contrasting indicia on the opaque paperboard substrate; applying a non-concealing protective coating to the opaque paperboard substrate over at least that portion of the substrate incorporating said indicia; applying the removable coating to the opaque paperboard substrate over at least an area of the substrate including the non-concealing protective coating.
Claim 14
Independent Claim
113 words
A method for preparing a gaming form, comprising the steps of; forming an opaque paperboard substrate by mixing paper fibers with a sufficient quantity of carbon black during formation of the substrate to render said paperboard substrate opaque; applying a pigment coating to the substrate for concealing the carbon black and rendering the substrate similar in appearance to a plain paperboard substrate; printing contrasting indicia on the opaque paperboard substrate; applying a non-concealing protective coating to the opaque paperboard substrate over at least that portion of the substrate incorporating said indicia; applying the removable coating to the opaque paperboard substrate over at least an area of the substrate including the non-concealing protective coating.
Claim 15
Dependent Claim
17 words
The method according to claim 12, wherein the opaque paper substrate is produced on a Fourdrinier machine.
Claim 16
Dependent Claim
12 words
The method according to claim 12, further comprising applying a confusion pattern.
Claim 17
Dependent Claim
11 words
The method according to claim 12, further comprising applying anti-tack material.
Claim 18
Dependent Claim
31 words
The method according to claim 12, wherein the paper fibers comprise about 80% recycled paper fibers and about 20% virgin fibers, and wherein the substrate is formed on a Fourdrinier machine.
