Description of the Related Art Inkjet recording is a recording method that enables high-speed printing with low noise, and is a recording method that is rapidly becoming popular in recent years. In this type of inkjet recording, recording is performed by ejecting a recording liquid as small droplets by heating or pressurizing the recording liquid and making the droplets adhere to a recording member such as paper.

いる。[Problems to be Solved by the Invention] When an organic solvent is used as the liquid medium of the recording liquid, it is possible to use various recording agents having excellent water resistance and light resistance. but,
The organic solvent very easily wets the fibers of paper, which is a recording member, and as a result, a so-called bleeding phenomenon occurs on plain paper. Therefore, the use of such a recording liquid is limited to printing on special paper whose surface is coated with inorganic fine particles or the like.
【０００５】液体の紙への浸透現象を考える場合、良く
使われる理論式として以下に示すルーカス・ウォッシュ

るか、表面張力γを低下させなければならない。[0007] This formula shows that the depth (h) that the liquid penetrates is:
It is shown that it is proportional to the square root of the cosine of the capillary radius (r), the surface tension of the liquid (γ), and the contact angle between the liquid and the capillary (θ), and is inversely proportional to the square root of the liquid viscosity (η). Generally, the print quality tends to improve as the penetration depth h per unit time is smaller, that is, the penetration speed is slower. When the liquid is an organic solvent, the contact angle θ with paper is approximately 0° and cos θ is 1, which is the maximum. Therefore, in order to reduce the penetration depth h, the viscosity η of the liquid must be increased or the surface tension γ must be decreased.

That is. Moreover, as the surfactant, a fluorine-based surfactant is preferable.
