Grease-resistant film, grease-resistant base material, and grease-resistant paper

An oil-resistant film, comprising:

• (A) a polyvinyl alcohol-based polymer;
• and
• (B) a polymer particle, which is a (meth)acrylic acid ester-based homopolymer particle, having a glass transition temperature of 40° C. or lower,
• wherein the polyvinyl alcohol-based polymer (A) is unmodified polyvinyl alcohol or modified polyvinyl alcohol,
• wherein the modified polyvinyl alcohol is ethylene-modified polyvinyl alcohol, silicon-modified polyvinyl alcohol, acetoacetyl group-modified polyvinyl alcohol, diacetone group-modified polyvinyl alcohol, or hydroxy group-modified polyvinyl alcohol,
• wherein the ethylene-modified polyvinyl alcohol is ethylene-vinyl alcohol copolymer and the content of an ethylene unit in the ethylene-vinyl alcohol copolymer is 0.5 to 15 mol. % relative to all structural units, and
• wherein the content of the polymer particle (B) is 1 part by mass or more and less than 150 parts by mass based on 100 parts by mass of the polyvinyl alcohol-based polymer (A).
