ものである。The present invention improves degreasing (water wettability in batch annealing) by using mineral oils having different fractionation end points (property of fractionation). As a matting oil to be interposed between the two, mineral oil having a fractionation end point of 120 to 245 ° C. is used.

い。If the fractional distillation end point of the mineral oil used as the matting oil is less than 120 ° C., it is easy to remove the adhering matting oil in the annealing process. Distillation temperature range changes, which adversely affects rolling performance, for example, the rolling speed is too high, wrinkles such as fish bone called herringbone, spots due to oil corrosion called oil pit, surface gloss defect etc. Defects appear, the matte surface of the aluminum foil is not sufficiently uniformized, and an aluminum foil having a good surface condition cannot be obtained. When the end point of the fractional distillation of mineral oil exceeds 245 ° C, the matting oil is not sufficiently removed in the annealing step, the wettability of the aluminum foil surface is deteriorated, and the adhesiveness with the resin and the printing step are poor. It has an adverse effect and is not preferable.

Since a mineral oil having a low temperature of 0 ° C. is used, a soft aluminum foil having good water wettability can be produced in a short time even by low temperature batch annealing in the method for producing an aluminum foil by polymerization rolling.
