Abstract
An aqueous ink composition for inkjet recording comprising a dye J-aggregate having an average particle size of 2 to 200 nm, and water-dispersible polymer particles having an average particle size of 10 to 400 nm, wherein the amount of the water-dispersible polymer particles is from one to ten times as much as that of the J-aggregate.
Claims12
An aqueous ink composition for inkjet recording comprising:
- a dye J-aggregate having an average particle size of 2 to 200 nm;
- and
- water-dispersible polymer particles having an average particle size of 10 to 400 nm, wherein the amount of the water-dispersible polymer particles is from one to ten times as much as that of the J-aggregate.
An image forming method comprising:
- applying an ink composition for inkjet recording comprising a dye J-aggregate having an average particle size of 2 to 200 nm, and water-dispersible polymer particles having an average particle size of 10 to 400 nm, wherein the amount of the water-dispersible polymer particles is from one to ten times as much as that of the J-aggregate,
- to an image-receiving material comprising an image-receiving layer and a substrate, wherein the image-receiving layer comprises an inorganic white pigment.
An image forming method comprising:
- applying an ink composition to an image-receiving material, wherein the ink composition comprises a dye J-aggregate, the image-receiving material comprises an image-receiving layer and a substrate, and the image-receiving layer comprises an inorganic white pigment;
- and
- uniformly applying water-dispersible polymer particles to the image-receiving material simultaneously with or subsequently to the application of the ink composition.
An image forming method comprising:
- uniformly applying water-dispersible polymer particles to an image-receiving material, the image-receiving material comprising an image-receiving layer and a substrate, wherein the image-receiving layer comprises an inorganic white pigment;
- and
- applying an ink composition comprising a dye J-aggregate to the applied water-dispersible polymer particles during the state that the ink composition can pass through the polymer particles to reach the image-receiving material.
