摘要： An ink composition includes a water resistant aluminum pigment and water. The water resistant aluminum pigment is formed of an aluminum pigment and a covering film that contains Si and is formed on the surface of the aluminum pigment. A 50% average particle diameter of a corresponding circle obtained by calculation from areas of X-Y plain surfaces of the aluminum pigment is in a range from 0.5 pm to 3 pm. The coverage ratio of the covering film on the surface of the aluminum pigment, calculated from presence ratios of C, O, Al, and Si detected by XPS measurement at an incident angle of 30°, is in a range from 30% to 90%.
