A mineral-oil-resistance-imparting coating material includes a copolymer of a monomer composition and an aqueous solvent in which the copolymer is dissolved and/or dispersed. The monomer composition contains a nitrile-group-containing unsaturated ethylenic monomer and a carboxy-group-containing unsaturated ethylenic monomer. To the total amount of the monomer composition, the content ratio of the nitrile-group-containing unsaturated ethylenic monomer is 21% by mass or more and 70% by mass or less. To the total amount of the monomer composition, the content ratio of the carboxy-group-containing unsaturated ethylenic monomer is 3% by mass or more and 10% by mass or less.
