Abstract
Abstract Printing inks and particularly fluorescent colored inks which provide outstanding color strength and dot resolution with planographic and letterpress printing processes are described. The inks comprise an intimate dispersion of colored resin particles in a vehicle containing specified amounts of certain alkyd resins, esters of modified rosin, carboxylated hydrocarbon resins and ink oil.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
198 words
An oleoresinous base printing ink composition which provides with planographic or letterpress printing processes outstanding color strength and dot resolution, said composition comprising an intimate dispersion of at least a coloring amount of finely-divided colored resin particles in a continuous phase liquid film-forming vehicle which is a non-solvent for the colored resin particles and comprises by weight 1. 55 to 75% of a binder resin system consisting essentially of, by weight, a. 15 to 30% of a drying oil modified alkyd resin having an acid number of 5 to about 20 and a Gardner-Holdt viscosity at 25° C. of Z4 to Z10, b. 40 to 70% of an ester of modified rosin having a drop softening point range of 145° to 175° C. and an acid number of 5 to about 30, and c. 15 to 30% of a low molecular weight, carboxylated hydrocarbon resin of petroleum origin having a Ring and Ball softening point of 110° to 180° C. and an acid number of 5 to about 20; and 2. 25 to 45% of an ink oil which is a solvent for the binder resin system and has a boiling point of at least about 200° C.
Claim 2
Dependent Claim
198 words
An oleoresinous base printing ink composition which provides with planographic or letterpress printing processes outstanding color strength and dot resolution, said composition comprising an intimate dispersion of at least a coloring amount of finely-divided colored resin particles in a continuous phase liquid film-forming vehicle which is a non-solvent for the colored resin particles and comprises by weight 1. 55 to 75% of a binder resin system consisting essentially of, by weight, a. 15 to 30% of a drying oil modified alkyd resin having an acid number of 5 to about 20 and a Gardner-Holdt viscosity at 25° C. of Z4 to Z10, b. 40 to 70% of an ester of modified rosin having a drop softening point range of 145° to 175° C. and an acid number of 5 to about 30, and c. 15 to 30% of a low molecular weight, carboxylated hydrocarbon resin of petroleum origin having a Ring and Ball softening point of 110° to 180° C. and an acid number of 5 to about 20; and 2. 25 to 45% of an ink oil which is a solvent for the binder resin system and has a boiling point of at least about 200° C.
Claim 3
Dependent Claim
25 words
The composition of claim 1 wherein the vehicle also contains 0.5 to 10% of an emulsifying agent and 0.2 to 4% of a gelling agent.
Claim 4
Dependent Claim
12 words
The composition of claim 2 wherein the resin particles are fluorescent colored.
Claim 5
Dependent Claim
14 words
The composition of claim 3 wherein the particles are of a modified sulfonamide resin.
Claim 6
Dependent Claim
25 words
The composition of claim 4 wherein the amount of fluorescent colored resin particles ranges from about 10 to about 70% by weight of the composition.
Claim 7
Dependent Claim
30 words
The composition of claim 4 containing from 2 to 20% by weight of the composition of ink additives selected from oils, ink vehicles, ink solvents, driers, waxes and mixtures thereof.
Claim 8
Dependent Claim
25 words
The composition of claim 6 wherein the amount of fluorescent colored resin particles ranges from about 25 to about 60% by weight of the composition.
Claim 9
Dependent Claim
45 words
In a process of printing using planographic or letter-press plates on single or multicolor presses, the improvement which comprises contacting the printing area of said plates with the composition of claim 7 to form an inked print and transferring the inked print to a substrate.
Claim 10
Dependent Claim
64 words
A process of printing by the offset technique using a single or multicolor press comprising the steps of treating a plate to provide printing and non-printing areas, applying an aqueous solution to the non-printing area of said plate, applying the composition of claim 7 to the printing area of said plate to form an inked print and transferring the inked print to a substrate.
Claim 11
Dependent Claim
14 words
The process of claim 9 wherein the substrate is paper stock or polypropylene sheet.
Claim 12
Dependent Claim
21 words
The process of claim 10 wherein the steps are repeated a multiplicity of times using different colored compositions of claim 7.
