Claim 0:
1. A solvent-based cold seal release lacquer comprising:
a) one or more solvents;
b) from 20 wt % to 70 wt % of one or more polyamide resins comprising greater than 90% biobased carbon, reported as a percentage of the total carbon that is carbon derived from plant or animal by-products; and
c) from 0.25 wt % to 5 wt % of one or more waxes, wherein the one or one or more waxes comprise greater than 70% biobased carbon, reported as a percentage of the total carbon that is carbon derived from plant or animal by-products;, wherein the cold seal release lacquer has a static coefficient of friction (CoFstatic) of 0.35-0.50; a kinetic coefficient of friction (CoFkinetic) of 0.20-0.35; wherein the cold seal release lacquer, when dried, comprises greater than 90% biobased carbon, reported as a percentage of the total carbon that is carbon derived from plant or animal by-products and meets the ASTM D6400 standard for compostability, wherein equal to or greater than 90% of the biobased carbon converts to CO2 within 180 days of composting; and wherein the cold seal release lacquer comprises from 0 to 1 wt % water.
