[0005] On the other hand, polyvinyl chloride has disadvantages such as deformation, dimensional change due to expansion and contraction at a temperature exceeding 60° C. There is no description of the rub resistance in heat printing at ℃ to 60℃, and an effective inkjet recording method that has the same rub resistance as non-aqueous inks on polyvinyl chloride using water-based inks has not been established so far.

Embodiment Construction

[0029] Hereinafter, preferred embodiments of the present invention will be described. The embodiments described below are examples for explaining the present invention. In addition, this invention is not limited to the following embodiment, Various modification examples implemented in the range which do not change the summary of this invention are included.

[0030] 1. Inkjet recording method

[0031] An inkjet recording method according to an embodiment of the present invention is characterized in that the inkjet recording method includes heating a recording medium formed of a polyvinyl chloride film to a temperature range of 40° C. to 60° C. by an inkjet recording apparatus. Above, the first process of ejecting the droplets of the water-based ink composition described later, and heating the recording medium to a temperature range of 40°C to 60°C, and combining the water-based ink ejected on the recording medium The second process of object drying; wherein, the water-based ...

Abstract

The invention relates to an ink jet recording process. Recording onto a non-ink-absorbing recording medium is performed using an aqueous ink composition containing a first solvent composed of at least one selected from 2-pyrrolidone, 1,3-dimethyl-imidazolidinone, and N,N'-dimethylpropylene urea, a second solvent composed of at least one selected from 1,2-hexanediol and 1,2-pentanediol, and a third solvent composed of at least one selected from glycol diethers and heating the non-ink-absorbing recording medium at 40 to 60 DEG C.

Description

technical field [0001] The present invention relates to a recording method for inkjet recording with water-based ink on a non-absorbent recording medium such as plastic whose recording surface is non-absorbent. Background technique [0002] Conventionally, non-aqueous inks mainly composed of organic solvents have been frequently used in recording methods for non-ink-absorbing recording media. For example, non-aqueous inkjet inks used to print high-quality images and characters on the surface of vinyl chloride-based resins such as polyvinyl chloride sheets commonly used as media such as outdoor advertisements usually contain pigments with excellent light resistance, A resin component for fixing the pigment on the surface of the vinyl chloride resin and an organic solvent capable of dissolving the resin component. Although these non-aqueous inks have the advantages of good water resistance due to the use of water-insoluble coloring agents and water-insoluble resin components,...
