Gaming form
First Claim
1. 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.

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.

12. 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. - View Dependent Claims (13, 14, 15, 16)
