Claims
- 1. A paper product bearing printing ink indicia protected by an overprint aqueous varnish having a formulation enhancing additive comprising a mixture of
- a. a finely divided unoxidized polyethylene having a molecular weight of about 700 to about 3,000;
- b. a finely divided oxidized polyethylene having a molecular weight of about 700 to about 3,000; and wherein components a and b comprise 1-6% of the mixture and;
- c. 2-40% an oxyalkylated essentially linear alcohol represented by the formula
- CH.sub.3 (CH.sub.2).sub.x O--(CH.sub.2 CH.sub.2 O).sub.n H
- wherein x is about 8 to about 75 and n is about 2 to about 65 and balance water.
- 2. The product of claim 1 wherein x is about 19 to about 44.
- 3. The product of claim 1 wherein n is about 4 to about 50.
- 4. The product of claim 2 wherein n is about 4 to about 50.
- 5. The product of claim 1 wherein the hydrocarbon is a mixture of unoxidized polyethylene and oxidized polyethylene.
- 6. The product of claim 7 wherein the oxidized polyethylene mixture comprises about 55-95% by weight of the polyethylene mixture.
- 7. A method of coating a paper product comprising the steps of forming an aqueous mixture of
- a. a finely divided unoxidized polyethylene having a molecular weight of about 700 to about 3,000;
- b. a finely divided oxidized polyethylene having a molecular weight of about 700 to about 3,000; and wherein components a and b comprise 1-60% of the mixture and,
- c. 2-40% of an oxyalkylated essentially linear alcohol represented by the formula
- CH.sub.3 (CH.sub.2).sub.x O--(CH.sub.2 CH.sub.2 O).sub.n H
- wherein x is about 8 to about 70 and n is about 2 to about 65 and balance water; adding the thus-formed aqueous mixture to an overprint aqueous varnish; mixing the aqueous mixture and varnish; and applying the resulting mixture to a paper product bearing printing ink indicia.
- 8. The product of claim 7 wherein x is about 19 to about 44.
- 9. The product of claim 7 wherein n is about 4 to about 50.
- 10. The product of claim 8 wherein n is about 4 to about 50.
- 11. The product of claim 7 wherein the hydrocarbon is a mixture of unoxidized polyethylene and oxidized polyethylene.
- 12. The product of claim 7 wherein the oxidized polyethylene mixture comprises about 55-95% by weight of the polyethylene mixture.
