Abstract

Official abstract text for this publication.

Provided is an ink jet printing method including: subjecting a printing medium to corona discharge treatment; and applying an ink containing an anionic pigment to a surface of the printing medium subjected to the corona discharge treatment, wherein the corona discharge treatment has a discharge quantity of 3,400 W·min/m2 or more.

First claim

Opening claim text (preview).

What is claimed is: 1. An ink jet printing method comprising: subjecting a printing medium to corona discharge treatment; and applying an ink containing an anionic pigment to a surface of the printing medium subjected to the corona discharge treatment, wherein the corona discharge treatment has a discharge quantity of 3,400 W·min/m 2 or more. 2. The ink jet printing method according to claim 1 , wherein the discharge quantity is 4,200 W·min/m 2 or more to 25,000 W·min/m 2 or less. 3. The ink jet printing method according to claim 1 , wherein the discharge quantity is 5,700 W·min/m 2 or more to 25,000 W·min/m 2 or less. 4. The ink jet printing method according to claim 1 , wherein the discharge quantity of the corona discharge treatment is adjusted by changing an output of the corona discharge treatment and a conveyance velocity of the printing medium. 5. The ink jet printing method according to claim 1 , wherein a conveyance velocity of the printing medium is 1.5 m/min or more to 4 m/min or less. 6. The ink jet printing method according to claim 1 , wherein an output of the corona discharge treatment is 3000 W or more to 5000 W or less. 7. The ink jet printing method according to claim 1 , wherein the ink contains anionic resin particles. 8. The ink jet printing method according to claim 1 , wherein the ink contains water, and a content of the water in the ink is 50.0 mass % or more to 95.0 mass % or less.
