インクジェット記録方式は記録部材として普通紙を使用することができ、また、カラー化が容易であるので、近年広く用いられている。 Inkjet recording methods have been widely used in recent years because plain paper can be used as a recording member and colorization is easy.
インクジェットに使用されるインクとして、インクがノズルに目詰まりするのを防止するために、水溶性染料及び多価アルコールを用いたものがある。しかし、この種のインクは耐水性や耐光性に劣り、特に熱ジェット方式のインクとして使用した場合には、ヒーター面の熱により染料が酸化され、インクがヒーター面に焦げつきやすく、吐出性が低下するという欠点がある。 As an ink used for inkjet, there is an ink using a water-soluble dye and a polyhydric alcohol in order to prevent the ink from clogging the nozzle. However, this type of ink is inferior in water resistance and light resistance, especially when used as a heat jet ink, the dye is oxidized by the heat of the heater surface, the ink tends to scorch on the heater surface, and the discharge property is reduced. There is a drawback of doing.
このような欠点を解消するために、顔料インクが提案されている。顔料インクには、界面活性剤や水溶性ポリマーにより顔料を水中へ分散させた顔料分散型インクと、水不溶性ポリマーの粒子中に顔料を含有させ、それを水中に分散させた顔料内包型インクとが提案されている。 In order to eliminate such drawbacks, pigment inks have been proposed.

Has been proposed.
顔料分散型インクを用いた場合には、前記欠点がかなり改善されるものの、耐水性及び耐光性が不十分であるという欠点がある。これに対して、顔料内包型インクは、耐水性及び耐光性に優れている。 In the case of using a pigment-dispersed ink, the above-mentioned drawbacks are considerably improved, but there is a disadvantage that water resistance and light resistance are insufficient. On the other hand, the pigment-containing ink is excellent in water resistance and light resistance.
