AN EMULSIFIED COATING COMPOSITION FOR APPLICATION TO PAPER AND PAPERBOARD PRODUCTS, COMPRISING (1) A WAXPOLYETHYLENE BLEND COMPRISING (A) A REFINED PARAFFIN WAX HAVING A MELTING POINT RANGING FROM ABOUT 122*F. TO ABOUT 165*F. AND PRESENT IN AMOUNTS OF FROM ABOUT 20% TO ABOUT 52% BY WEIGHT BASED UPON THE WEIGHT OF SAID WAX-POLYETHYLENE BLEND, (B) A SYNTHETIC HARD PARAFFIN WAS HAVING AMELTING POINT RANGING FROM ABOUT 212*F. TO ABOUT 225*F. AND PRESENT IN AMOUNTS OF FROM ABOUT 35% TO ABOUT 75% BY WEIGHT, BASED UPON THE WEIGHT OF SAID WAX-POLYETHYLENE BLEND AND (C) A POLYETHYLENE RESIN HAVING AN AVERAGE MOLECULAR WEIGHT RANGING FROM ABOUT 5,000 TO ABOUT 12,000 AND PRESENT IN AMOUNT OF FROM ABOUT 6% TO ABOUT 20% BY WEIGHT BASED UPON THE WEIGHT OF SAID WAX-POLYETHYLENE BLEND AND (2) AN EMULSIFICATION BASE COMPRISING (A) A PRIMARY EMULSIFIER SELECTED FROM THE GROUP CONSISTING OF SAPONIFIED OXYGENATED SYNTHETIC HARD PARAFFIN WAXES HAVING A SOLIDIFICATION POINT RANGING FROM ABOUT 185*F. TO ABOUT 212*F. AND SAPONIFIED OXYGENATED NATURAL HARD PARAFIN WAXES HAVING A SOLIDIFICATION POINT FROM ABOUT 185*F. TO ABOUT 200*F. AND PRESENT IN AMOUNTS OF FROM ABOUT 0.1% TO ABOUT 7% BY WEIGHT BASED UPON THE WEIGHT OF SAID WAX-POLYETHYLENE BLEND, (B) A SECONDARY EMULSIFIER WHICH IS A WATER SOLUBILIZED PROTEIN PRESENT IN AMOUNTS OF FROM ABOUT 1.5% TO ABOUT 15% BY WEIGHT, BASED UPON THE WEIGHT OF SAID WAXPOLYETHYLENATED BLEND AND (C) WATER PRESENT IN AMOUNTS OF FROM ABOUT 80% TO ABOUT 98% BY WEIGHT BASED UPON THE WEIGHT OF SAID WAX-POLYETHYLENE BLEND.

Claim 3
Dependent Claim
90 words
A PROCESS OF PREPARING EMUSLIFIED COATING COMPOSITIONS FOR APPLICATION TO PAPER AND PAPERBOARD PRODUCTS WHICH COMPRISES SLOWLY ADDING THE HOMOGENEOUS MIXTURE OF THE WAX-POLYETHYLENE BLEND OF CLAIM 1 AT A TEMPERATURE RANGING FROM 212*F. TO ABOUT 225*F. TO THE EMULSIFICATION BASE OF CLAIM 1 WHICH IS MAINTAINED AT A TEMPERATURE RANGING FROM ABOUT 200*F. TO ABOUT 212*F., AGITATING THE RESULTING MIXTURE OF SAID BLEND AND EMULSIFICATION BASE TO OBTAIN AN EMULSION AND THEREAFTER STABILIZING SAID EMULSION BY REDUCING THE PARTICLE SIZE OF THE PARTICLES CONTAINED THEREIN TO BELOW 0.002 MILLIMETER.
