ABSTRACT:
There is provided a thermosetting resin comprising a polyglycidyl ether of a bisphenol of relatively low molecular weight, which is upgraded in molecular weight by reaction with additional bisphenol and esterified with certain fatty acid mixtures from a tall oil source. When these resins are reduced with organic solvents to approximately 50 percent solids content they are useful exterior coatings for lap-seam beverage cans in which the seam is sealed with a nylon adhesive.
