Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 168 words
A golden-colored printing ink consisting essentially of a golden-colored powder and vehicle comprising a combination of a synthetic resin varnish; a gel varnish; a tung oil compound varnish or a petroleum solvent, and an amine compound which serves to improve the relief of the golden-colored powder and to prevent change in its color and properties, said golden-colored powder being a brass alloy, including aluminum in the form of fine foils and treated at the surface with a fatty acid, said vehicle and said golden-colored powder being in the form of a sol and wherein said synthetic resin varnish is composed of a phenol resin and a xylene resin, and said gel varnish is composed of a compound varnish of the same component as said synthetic resin varnish with at least one gelling agent added thereto selected from the group consisting of aluminum alcoholate compounds and aluminum chelate compounds, said gel varnish being present in an amount of 10-16% by weight, based on the weight of the printing ink.
Claim 2
Dependent Claim 168 words
A golden-colored printing ink consisting essentially of a golden-colored powder and vehicle comprising a combination of a synthetic resin varnish; a gel varnish; a tung oil compound varnish or a petroleum solvent, and an amine compound which serves to improve the relief of the golden-colored powder and to prevent change in its color and properties, said golden-colored powder being a brass alloy, including aluminum in the form of fine foils and treated at the surface with a fatty acid, said vehicle and said golden-colored powder being in the form of a sol and wherein said synthetic resin varnish is composed of a phenol resin and a xylene resin, and said gel varnish is composed of a compound varnish of the same component as said synthetic resin varnish with at least one gelling agent added thereto selected from the group consisting of aluminum alcoholate compounds and aluminum chelate compounds, said gel varnish being present in an amount of 10-16% by weight, based on the weight of the printing ink.
