の一形態として知られている。2. Description of the Related Art A pressure-sensitive copying paper is composed of a paper on which a color-forming agent microcapsule composition mainly containing microcapsules containing an oily substance in which an electron-donating organic color-forming agent or the like is dissolved is coated on the back surface of a support. A medium paper on which a color developer composition mainly composed of an electron-accepting color developer that develops color when it comes into contact with the color developer is applied to the surface of the support, and the color former microcapsule composition is applied to the back surface And a lower paper coated with a developer composition on the surface of a support, and generally used in combination of upper paper-lower paper or upper paper-middle paper-lower paper in order of writing pressure, pressure of a printer, etc. The microcapsules are destroyed and the oil dissolving the color former transfers to the color developing layer,
The color is developed by reacting with the color developer. In addition, a self-coloring type pressure-sensitive copying paper in which a color former and a developer are coated on the same surface of a support so that pressure-sensitive recording can be performed with one sheet is also known as one form thereof.

式による印刷が普及してきている。[0003] Pressure-sensitive copying paper is used for various types of slips, and those slips have been used in the form of form printing by offset printing, letterpress printing, or the like. In recent years, along with the technical development of the ink jet recording method, an example in which the ink jet recording method is used for form printing has come to be seen. The use of the ink jet recording method has the advantages that plate making is not required, the format can be easily changed, and the like, and can be used for printing small lots or printing variable information such as bar codes on slips. Ink-jet printing has also become widespread in pressure-sensitive copying paper.

Inorganic color developing agents such as acid clay, activated clay and attapulgite, and organic developing agents such as phenol-formaldehyde resin, polyvalent metal salt of salicylic acid derivative, polyvalent metal salt of terpene phenol resin and polyvalent metal salt of salicylic acid-containing copolymer. Coloring agents are known. However, an ink jet recorded image formed by using an ink jet recording method on a pressure-sensitive copying color developing sheet using a conventional inorganic color developing agent becomes a blurred and unclear image, and has poor water resistance and is wet with water. In addition, there were problems such as a decrease in the density of an ink jet recorded image.

いという欠点があった。[0005] In order to improve this, it is described that a cationic substance is blended in the color developing layer of the pressure-sensitive copying sheet. However, it is usually desirable that the coating liquid is anionic in order to reduce the viscosity or stabilize the viscosity of the developing layer coating liquid, but a cationic substance is blended in this anionic developing layer coating liquid. In such a case, the coating liquid is thickened or gelled, which makes coating very difficult. In addition, the cationic substance acts on the color developer to lower the color developing ability, the color density of the pressure-sensitive recording decreases, and there is a drawback that sufficient quality as pressure-sensitive copying paper cannot be obtained.

pHを高く調整することが一般的に行なわれている。Conventionally, in a color developing sheet for pressure-sensitive copying using an inorganic color developing agent such as activated clay, a metal salt is sometimes blended as a dispersing agent for dispersing the color developing agent or pigment in water.
Further, if the pH of the color developing layer is small, there are problems such as deterioration of the color image over time and inferior desensitizing effect even when desensitized printing is performed. It is common practice to adjust the pH of the color developing layer coating material to a high value using a metal salt such as acid soda.

た時の減感効果が低くなる。[0009] However, when printing is performed by an ink jet recording method on a pressure-sensitive copying color developing sheet provided with such a color developing layer, the recorded image has only bleeding or poor water resistance. According to the study of the present inventors, when adjusting the color developing layer coating, when a metal salt-based substance such as a dispersant or a pH adjuster is not blended, there is no bleeding of the ink jet recorded image, and the water resistance is good. there were. However, if the paint pH is 9
If the adjustment is not made as described above, the deterioration of the color image over time when the color is formed as the pressure-sensitive copying paper is severe, and the desensitizing effect when the desensitizing ink is printed is reduced.

When the pH of the color developing layer coating is adjusted using either aqueous solution or aqueous ammonia solution, there is no bleeding of the ink jet recorded image, the water resistance is improved, and the deterioration of the pressure-sensitive coloring image can be reduced, and the desensitizing effect can be reduced. It has been found that a good color-developed sheet for pressure-sensitive copying can be obtained, and the present invention has been completed.
