Abstract: [The present invention] provides a surface treatment method for recorded matter which can improve the weather resistance characteristics such as light resistance, gas resistance and the like of recorded matter in which images are recorded on the recording medium, as well as providing a surface-treated product using this surface treatment method, and a surface treatment apparatus. The surface treatment method of the present invention is characterized in that the surface of recorded matter in which images are recorded on a recording medium is treated using a specified treatment agent. The abovementioned treatment agent is a treatment agent which contains one or more active constituents selected from the group consisting of sulfur compounds, nitrogen compounds, fluorine compounds, natural resins and synthetic resins, or a treatment agent comprising water or an organic solvent.

Abstract: An ink jet recording method which can inhibit feathering or bleeding in a print and provide a sharp color image is disclosed. The ink jet recording method according to the present invention comprises the steps of: ejecting a droplet of an ink composition, comprising a colorant, a thermoplastic resin, and water, onto a recording medium to deposit the ink droplet on the recording medium, and heating the recording medium with the ink droplet deposited thereon at the softening temperature of the thermoplastic resin or higher temperature so as to effectively inhibit feathering or bleeding of the ink.

Abstract: Two intermediate transfer ink jet recording methods and a recording device suitable for practicing the methods and an ink composition for use in the methods are disclosed. The first recording method comprises forming jetting an ink composition containing a thermoplastic resin on an intermediate transfer drum to form an ink image, heating the ink image to at least the softening or melting temperature of the thermoplastic resin to bring the ink image to a film form and then transferring the ink image to recording paper. The second recording method comprises jetting an ink composition containing a thermoplastic resin on an intermediate transfer drum to form an ink image, heating the ink image to form a concentrated ink image, transferring the concentrated ink image to recording paper and then heating the transferred ink image to at least the softening or melting temperature of the thermoplastic resin.

Abstract: The present invention disclosed herein provides a hot-melt ink composition that can provide a good fixing strength and a high quality of print independently of the kinds of recording media.

Abstract: A hot-melt ink composition for an ink jet printer, comprising a coloring agent, and a vehicle which comprises a dialkylbenzenesulfonamide, a monoalkylbenzenesulfonamide, and a resin; and a hot-melt ink composition comprising from 10 to 30 wt. % of a coloring agent, and a vehicle. These ink compositions can produce high quality images which have improved resistance to abrasion and are free from blooming.
