Abstract
Abstract The present invention relates to an aqueous printing ink composition and method for improving printing using such aqueous based printing inks. The composition is comprised of a physical mixture of polyurethane resin, polyethylene resin and water as the vehicle. The invention provides a family of water-based inks with enhanced physical and mechanical properties. The inks have superior abrasion resistance and good adhesion to various substrates including metal and plastics.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
58 words
The method of improving the adhesion and abrasion resistance of print on a substrate which comprises adding to an aqueous printing ink a major amount of an aqueous mixture of polyurethane resin and polyethylene resin having a solids ratio ranging from about 1:9 to 1:1 and applying by a printing technique the resultant ink mixture to a substrate.
Claim 2
Independent Claim
58 words
The method of improving the adhesion and abrasion resistance of print on a substrate which comprises adding to an aqueous printing ink a major amount of an aqueous mixture of polyurethane resin and polyethylene resin having a solids ratio ranging from about 1:9 to 1:1 and applying by a printing technique the resultant ink mixture to a substrate.
Claim 3
Dependent Claim
21 words
