Problems solved by technology

However, the solvent of water-based ink contains water as the main component, so it is difficult for the ink liquid film that lands on the recording medium to dry compared to the case where the solvent is an organic solvent.

Abstract

The invention provides an image forming method which is excellent in spraying property of ink composition and can form images with excellent glossiness. An image forming method uses an ink set that includes applying a liquid composition onto a recording medium; further applying an ink composition onto the recording medium with an ink jet method to form an image; drying the image at a surface temperature of the image of 35 to 55 DEG C until a difference between a residual water content of a non-image portion on the recording medium and a residual water content of a image portion where an application amount of the ink composition is the maximum is 2 to 4 g / m<2>; and irradiating the image with active energy rays: the ink set includes the ink composition containing at least a pigment, water, 3 % by mass or less of polymer particles, and 5 % by mass to 15 % by mass of polymerizable compound having an acrylamide structure represented by the formula (1); and the liquid composition containing an aggregation component.

Description

technical field [0001] The present invention relates to an image forming method using an inkjet method. Background technique [0002] Inkjet technology is an image recording method that is widely expected in the fields of office printers, home printers, and commercial fields because it can form desired images on various recording media. [0003] As inks used in inkjet recording, in addition to solvent systems, water-based inks are also attracting attention from the viewpoint of considering the global environment and work environment. However, since the solvent of the water-based ink contains water as the main component, it is difficult to dry the ink liquid film landed on the recording medium compared to the case where the solvent is an organic solvent. In particular, in recent years, high-speed printing has been demanded, and various technologies focusing on drying of ink liquid films and curing of ink liquid films during image formation have been disclosed. [0004] As a...
