する様々な提案が成されてきた。2. Description of the Related Art In recent years, ink jet printers have been rapidly spread due to advantages such as low noise, low running cost, and easy colorization. However, when recording on plain paper, in addition to initial quality problems such as bleeding, density, color tone, show-through, etc., there were problems related to the robustness of images such as water resistance and weather resistance. Proposals have been made.

があり、また鉛筆やペンによる加筆性の問題があった。[0003] As a solution to these problems, when an image is formed with ink, a recording material, such as plain paper, is coated with a material for fixing the dye in the ink on the surface of the recording material in advance, or the surface of the recording material is fixed. Use of a recording material coated with a white pigment or a water-soluble polymer is disclosed in JP-A-56-86789, JP-A-55-144172, and JP-A-52-5.
No. 3012 or JP-A-56-89594. However, this method has the inconvenience of not being able to freely use nearby paper because it is necessary to purchase specially coated paper in advance, and also has the problem of rewriting with a pencil or pen. there were.

という問題がある。In order to suppress bleeding at a color boundary such as a two-color overlapping portion, a surfactant is added to the ink to increase the ink permeability.
No. 5,269, for example. This method is effective for solving bleeding at a color boundary such as a two-color overlapped portion and smear (image stain due to contact after printing) because ink penetrates into recording paper at a high speed. Image cannot be resolved. Further, a method of adding a volatile solvent to the ink is disclosed in Japanese Patent Application Laid-Open No. 55-66976. The same effect as that of the permeable ink can be obtained, but the nozzle is liable to be clogged. In addition, the use of ink containing a pigment as a coloring agent has also been increasing in order to improve water resistance and light resistance, but it is difficult to maintain the reliability around the nozzle such as clogging with the ink containing the pigment, Further, when high color reproducibility such as a photographic image or CG is required, there is a problem that the color development of cyan or magenta becomes insufficient and a satisfactory image cannot be obtained.

小さくなるという問題があった。In order to solve such a problem, Japanese Patent Application Laid-Open No. 56-89595 discloses that a polymer solution such as carboxymethyl cellulose, polyvinyl alcohol, or polyvinyl acetate is sprayed on a recording material in advance. An ink jet recording method has been proposed in which printing is performed by ejecting ink to a portion where the polymer solution has adhered. However, although this method can improve the sharpness of a printed image, it does not provide an effect on improving the dryness of the printed image, so that the effect of improving the image quality of a color image is not so recognized. Also,
An ink jet recording method is disclosed in which an image recording accelerating liquid containing a compound that insolubilizes a dye in an ink is deposited on a recording material by an ink jet method, and then the ink is ejected to a portion where the image recording accelerating liquid is adhered to perform printing. 64-63
185, JP-A-8-20159 or JP-A-8-20161, but this method has a large amount of water attached to the two-color overlapping portion, so that bleeding at the color boundary can be sufficiently prevented. And there is a problem that show-through of the ink is large. Further, there is a problem that cockling (undulation) of the recording material occurs. In addition, since the image recording accelerating liquid is sprayed by the ink jet head, the viscosity and surface tension of the liquid are restricted in order to obtain stable ejection, and the nozzle diameter and the composition of the liquid are restricted in order to prevent clogging. There is a problem that the degree of freedom is significantly reduced due to the added condition.
