Claims12
An ink set comprising
- an ink composition including an encapsulated black pigment in which a black pigment is coated with a polymer resin;
- and
- an ink composition including an encapsulated color pigment in which a color pigment is coated with a polymer resin,
- wherein a volume average diameter (D1) of the encapsulated black pigment is in a range of 120 to 150 nm, a glass transition temperature (Tg1) of the encapsulated black pigment is in a range of 30 to 50° C., a volume average diameter (D2) of the encapsulated color pigment is in a range of 90 to 120 nm, and a glass transition temperature (Tg2) of the encapsulated color pigment in a range of 10 to 30′C, and
- wherein D1-D2 is in a range of 1 to 60 nm, and Tg1-Tg2 is in a range of 1 to 40° C.
