Abstract:
The ink set of the invention includes a first ink composition and a second ink composition. The first ink composition contains a first pigment and an alkanediol having 6 or less carbon atoms and having a normal boiling point of 245° C. or more. The content of the first pigment is 1.5% by mass or more, and the content of the alkanediol is 3% by mass or more and 20% by mass or less. The second ink composition contains a second pigment and a penetrant other than the alkanediol. The content of the second pigment is less than 1.5% by mass. The penetrant contained in the second ink composition has an osmotic force higher than that of the alkanediol contained in the first ink composition.
