Claims4
A method of coating paperboard comprising the step of applying to said paperboard a board coating composition comprising:
- (a) pigment;
- and
- (b) a binder wherein said binder comprises the polymerization reaction product of cationic starch and vinyl acetate monomer.
A method of coating paperboard comprising the step of applying to said paperboard a board coating composition comprising:
- (a) pigment;
- and
- (b) a binder comprising the polymerization product of a cationic starch and a vinyl acetate product wherein the weight ratio of the vinyl acetate component to the cationic starch component is from about 20:100 to about 300:100.
A method of coating paperboard comprising the step of applying to said paperboard a board coating composition comprising:
- (a) pigment;
- and
- (b) a binder comprising the polymerization product of a cationic starch and a vinyl acetate product wherein the board coating composition is applied to said paperboard at a level of from about 0.5 to about 10 pounds per 1000 square feet per side.
