Claims23
A coating composition comprising ethylene acrylic acid (EAA) and N-methylpyrrolidone (NMP).
A method of producing durable high gloss printed stock including the steps of:
- advancing a printed substrate into a coating station,
- coating the printed surface with a composition of ethylene acrylic acid (EAA) and N-methylpyrollidone (NMP) in an aqueous carrier, and,
- drying the coating.
A method of making a durable high gloss coating composition comprising the steps of:
- providing a quantity of water,
- mixing a quantity of ethylene acrylic acid (EAA) with the water to form an aqueous dispersion thereof, and,
- adding a quantity of N-methylpyrollidone (NMP) to the EAA dispersion.
The method of making a bright printing ink comprising the steps of:
- providing a quantity of water,
- mixing a quantity of ethylene acrylic acid (EAA) with the water to form a dispersion therewith,
- adding a quantity of pigment, and,
- adding a quantity of N-methylpyrollidone (NMP) to the EAA-pigment dispersion.
