Embodiment

[0097] Hereinafter, the present invention will be described in detail using examples, but the present invention is not limited to them.

[0098] Preparation of white ink composition

[0099] Mix and stir metal oxides, hollow resin particles, resins, organic solvents, polyols, tertiary amines, surfactants, and ion-exchanged water in the amount shown in Table 1, filter with a metal filter with a pore size of 5 μm, and degas with a vacuum pump The respective ink compositions of Examples 1 to 6 and Comparative Examples 1 to 6 were obtained. In addition, the unit of the numerical value described in Examples 1-6 and Comparative Examples 1-6 of Table 1 is mass %, For metal oxide, hollow resin fine particle, and polyurethane resin particle, it is solid content conversion.

[0100] The commercial item "NanoTek (R) Slurry" (manufactured by Sea Chemicals Co., Ltd.) described in Table 1 was used as the metal oxide. NanoTek (R) Slurry is a slurry containing titanium dioxide with an avera...

Abstract

The present invetnion provides an ink composition having good erasibility, especially suitable for ink jetting recording mode. The ink composition includes a polyurethane resin and at least one selected from a metal compound and hollow resin particles as a colorant, and in the ink composition described above, the polyurethane resin is a polycarbonate-based or a polyether-based anionic polyurethaneresin.

Description

technical field [0001] The present invention relates to an ink composition, a recorded matter using the same, a recording method, and a recording device. Background technique [0002] Conventionally, a white ink composition containing hollow polymer particles is known as a white color material (for example, refer to Patent Document 1). The hollow polymer microparticles have a cavity inside, and the outer shell is formed of a liquid-permeable resin. With this structure, in the ink composition, the internal cavity of the hollow resin particles is filled with the solvent, and since the specific gravity of the hollow resin particles is substantially the same as that of the ink composition, the hollow resin particles can be stably dispersed in the ink. composition. Moreover, when an image is formed on a recording medium using the ink composition, the inner space of the hollow resin particle is replaced by air during drying, so the hollow resin particle utilizes the Scattering ...
