- 12. The method of claim 8 wherein the .[.oxidized polyethylene mixture.]. .Iadd.hydrocarbon further .Iaddend.comprises .[.about 55-95% by weight of the polyethylene mixture.]. .Iadd.unoxidized polyethylene.Iaddend..
- 13. An aqueous varnish having incorporated therein a formulation enhancing additive comprising a mixture of
- a. a finely divided mostly linear aliphatic hydrocarbon .[.and/or.]. .Iadd.or a .Iaddend.modified hydrocarbon .Iadd.or mixtures thereof .Iaddend.having a molecular weight of about 300-3,000 .Iadd.selected from the group consisting of (i) a copolymer of ethylene and either propylene, butylene, vinyl acetate or acrylic acid; (ii) petroleum-derived waxes; (iii) Fischer-Tropsch waxes; (iv) natural wax; and (v) partially oxidized hydrocarbon.Iaddend.; and
- b. a compound represented by the formula: ##STR5## wherein R and R.sub.1 are independently hydrogen or C.sub.1 -C.sub.10 alkyls; R.sub.2 is hydrogen or methyl, x is about 8 to about 75; and n is about 2 to about 65.
- 14. The varnish of claim 13 wherein x is about 19 to about 44.
