インクを噴射できない。Conventionally, in inkjet recording, there has been a desire for an inkjet recording paper on which ink dries quickly and can form clear prints with high density, but no paper that can satisfy this demand has yet been obtained. In other words, when recording paper with good ink absorption and fast drying speed, such as unsized paper, is used as recording paper, the ink does not stay on the surface layer but is absorbed into the interior and spreads over a flat surface. This causes the dye to bleed. For this reason, it was not possible to obtain clear print with a density of (1). When high-quality paper or plain paper with relatively low ink absorption and densely entangled paper fibers is used as recording paper to increase print density, the ink dries slowly and can damage the user's hands and clothing. Made it dirty. In addition, attempts have been made to increase the amount of dye added to the ink in order to increase the printing density, but in this case, the ink cannot be stably ejected because the nozzles become clogged, especially when the ink ejection is stopped.

用紙を提供するものでおる。Therefore, it is an object of the present invention to provide an inkjet recording paper that solves the above-mentioned drawbacks.More specifically, it is an object of the present invention to provide an inkjet recording paper that solves the above-mentioned drawbacks. An object of the present invention is to provide an inkjet recording paper with increased print density without reducing drying speed.

に染着する。In the present invention, since the reactive substance of the aromatic carboxylic acid of the phenol or solid acid is present in the surface layer or inside of the recording paper, ink droplets flying from the ink jet recording device adhere to the recording paper. Then, the dye in the ink comes into contact with the reactive substance on the recording paper, causing several tens of
It forms aggregates of ~100 μm in size and stains paper fibers near the surface of the recording paper.

The tiny droplets of dye that have passed through the μ filter come into contact with the reactive substances on the recording paper and aggregate, so they do not penetrate into the recording paper. Furthermore, since the hiding power is extremely high, images with high print density can be obtained.

ならいずれでもよい。In the inkjet recording paper of the present invention, in order to contain the reactant of the phenol or the aromatic carboxylic acid of the solid acid in the paper surface layer or inside, the reactant-containing surface layer can be formed by a conventionally known method such as a liquid coating method. The reactive substance may be formed on the surface of the paper by a method, or the reactant may be mixed into the paper material during the paper manufacturing process. The paper used in the present invention may be any paper that has been conventionally used as recording paper.

This limitation includes water-based inks containing acid dyes. These aqueous solutions exhibit alkalinity and maintain a good dissolved state, and maintain a stable jetting state without clogging the filter or nozzle during long-term continuous or intermittent jetting. When it comes into contact with it, it forms an aggregate with great hiding power.

Improving the image quality by using the existing ink as is The recording paper of the present invention was obtained by coating the paper surface and drying it. When printed on the recording paper thus obtained using an inkjet recording device manufactured by Ricoh, characters with higher reflection density and less blurring were obtained than characters printed on Punto paper that was not subjected to the above treatment. Further, there was no change in the drying time of the ink. The composition of the ink (6) used for printing was C, 1 as a dye, and acid black 1.
3 parts by weight, polyethylene glycol as a wetting agent (
The molecular weight (200) was 30 parts by weight, and the water was 67 parts by weight.

Red letters with higher image density and less bleeding were obtained than letters printed on thin paper. The ink composition used at this time was 4 parts by weight of C,1, Acid Red 37 as a dye, 15 parts by weight of polyethylene glycol (molecular weight 400) as a wetting agent, 15 parts by weight of ethylene glycol, and 66 parts by weight of water.

When the recording paper thus obtained was printed using an inkjet recording device similar to Example 1, red characters with higher image density and less bleeding were obtained compared to characters printed on untreated paper without the above treatment. Ta. The ink composition used at this time was 3 parts by weight of C,1 and Direct Blue 22 as dyes, 25 parts by weight of polyethylene glycol (molecular weight 400) as wetting agents, 5 parts by weight of triethylene glycol, and 67 parts by weight of water. .
