Abstract: coating compositions comprising polyalkyleneimine and cellulose acetate propionate in solution, and related process and product, are disclosed. Such compositions are particularly useful as primer coatings for substrates of regenerated cellulose, paper and paperboard where cellulose ester top coatings are used. Use of such compositions as primer coatings improves adhesion of the top coating to the substrate, particularly where the coated substrate is heat-sealed, for example, in packaging applications. Also, the coating composition provides increased resistance to blocking, which is especially important where the substrate is sheet material wound in a roll.
