Abstract
A water-based ink set for ink-jet recording includes: the infrared absorptive ink that contains the antimony-tin composite oxide fine particles and water; and the color ink that contains the coloring agent and water. The water-based ink set for ink-jet recording is applicable to an ink-jet recording method for recording an image by ejecting the inks onto a recording medium to cause the inks to adhere to the recording medium. When an image having infrared absorptivity is recorded, at least the infrared absorptive ink is ejected onto a recording medium to cause the infrared absorptive ink to adhere to the recording medium.
Claims11
A water-based ink set for ink-jet recording, comprising:
- a colorless transparent infrared absorptive ink comprising an antimony-tin composite oxide fine particle and water;
- and
- a color ink comprising a coloring agent and water.
An ink-jet recording method for recording an image by ejecting at least one ink of a plurality of different inks constituting an ink-set for ink-jet recording onto a recording medium to cause the ink to adhere to the recording medium, wherein the ink-set for ink-jet recording is a water-based ink set for ink-jet recording comprising:
- a transparent colorless infrared absorptive ink that comprises an antimony-tin composite oxide fine particle and water;
- and a color ink that comprises a coloring agent and water, and wherein an image having infrared absorptivity is recorded by ejecting at least the infrared absorptive ink onto a recording medium to cause the infrared absorptive ink to adhere to the recording medium, and wherein an invisible image is recorded with the infrared absorptive ink and a visible image is recorded with the color ink, and wherein the invisible and visible images are formed such that at least parts thereof overlap with each other on the recording medium.
An ink-jet recording method for recording an image by ejecting at least one ink of a plurality of different inks constituting an ink-set for ink-jet recording onto a recording medium to cause the ink to adhere to the recording medium, wherein the ink-set for ink-jet recording is a water-based ink set for ink-jet recording comprising:
- a transparent colorless infrared absorptive ink that comprises an antimony-tin composite oxide fine particle and water;
- and a color ink that comprises a coloring agent and water, and wherein an image having infrared absorptivity is recorded by ejecting at least the infrared absorptive ink onto a recording medium to cause the infrared absorptive ink to adhere to the recording medium, and wherein an invisible image is recorded with the infrared absorptive ink and a visible image is recorded with the color ink, and wherein the invisible and visible images are formed so as not to overlap with each other on the recording medium.
