PROBLEM TO BE SOLVED: To provide a cold-rolled oil composition excellent in seizure resistance and oil-water separation and a cold rolling method using the same. A direct oil-type cold rolling oil composition comprising the following components 1 to 3. Ingredient 1: mineral oil, synthetic ester oil or animal and vegetable oil, Component 2: Group A cationic monomer homopolymer or copolymer, or Group A cationic monomer and Group B monomer, and Component 3: Sulfur, phosphorus-sulfur, or phosphorus extreme pressure agent. Group A: A compound represented by the following formula (1), (2) or (3). Group B: An ester or amide of acrylic acid or methacrylic acid having an alkyl group or alkenyl group in the side chain. Formula (1) [0001] [Chemical 1] Equation (2) CH 2 = CR 3 -CO-NH- (CH 2) m NR 4 R 5 Equation (3) CH 2 = CR 6 -CO-O- (CH 2) n NR 7 R 8 R 1 , R 2 , R 3 and R 6 are hydrogen or methyl, R 4 , R 5 , R 7 and R 8 are alkyl, m and n are 1 to 5; |
