In recent years, with the rapid spread of office automation, a large amount of information recording paper such as pressure-sensitive recording paper, heat-sensitive recording paper, electrostatic recording paper, and ink-jet recording paper has come to be used. In recent years, the amount of thermal energy pattern forming materials used for various industrial or consumer uses, for example, dry film resists and resist inks for forming printed circuit boards has been increasing. These various recording materials form an image by performing a chemical change accompanied by a hue change from colorless to colored or from colored to colorless in response to energy such as pressure, heat and electromagnetic waves. Has achieved its purpose.

As a chemical means for forming such an identifiable color image, for example, in the case of information recording paper such as pressure-sensitive recording paper and heat-sensitive recording paper, a basic coloico dye such as a phthalide or fluoran dye and a phenol resin -A color reaction by contact with an organic or inorganic solid acid such as salicylic acid derivative or acid clay is generally used.

These compounds quickly form a chromogenic complex upon contact and develop colors in various hues corresponding to each compound, but the formation of this chromogenic complex is reversible, and water, oils and fats, oxygen-containing polar organic The equilibrium shifts due to contact with a solvent or a temperature change, and the color disappears.
For this reason, the recorded image has a serious drawback of lacking stability to the environment, and there has been a strong demand for improvement. In order to improve such storage stability, the present inventors have developed a pressure-sensitive recording unit and a heat-sensitive recording unit (JP-A-57-107-1) using a novel redox coloring method.

According to such a novel coloring method, since the coloring image is formed irreversibly on the recording paper, the instability of the coloring image can be eliminated. For example, a compound such as leuco crystal violet has long been known as a color-forming compound used in this color-forming method, but leucotriphenylmethane dyes represented by this compound are generally susceptible to air oxidation during storage. Thus, there has been a problem in controlling the color development or operating temperature during long-term storage before use, and further improvement has been demanded.

(In the formula, Y represents an electron-withdrawing group, and n represents an integer of 1 to 4.) The coloring substance (II) obtained by such a redox coloring method has a long conjugated system, and thus has a conventional tria. Many of the reel methane compounds exhibit a deep hue not found in methane compounds.In addition to diversifying the hues of recorded images, they are more stable in air oxidation resistance during storage than conventional leukotriaryl methane compounds. As a result, the tendency of the paper surface to be stained before use (for example, the coloring of the microcapsule-coated surface in the case of pressure-sensitive recording paper) is significantly reduced, and the amount of the stain inhibitor used is reduced or eliminated. Things become possible. In addition, since the color development obtained in this way is irreversible, the stability in an image storage environment is very good, and the reaction between a lactone dye and an acidic substance conventionally used in this field is performed. The decoloration due to contact with water or a polar organic solvent, which is observed in the above, is hardly observed. Therefore, the pressure-sensitive or heat-sensitive recording material constituted by using the dye for recording material represented by the general formula (I) of the present invention and a quinone derivative is extremely useful from the viewpoint of preservation of a color image and diversification of a color hue. It is. In addition, the system using the recording dye can significantly reduce the color development caused by the organic solvent or fingerprint, which is a drawback of the thermal recording paper using the redox or chelate color forming agent, and has high practical value. It is a remarkable feature of the coloring material.

Further, an ultraviolet-sensitive material constituted by using the dye for a recording material of the present invention, in particular, an ultraviolet-sensitive material by free radical photography using an organic halogen compound as a coloring aid, is a conventional leucotriarylmethane compound such as leucocrystal. Compared to infectious external wire materials using violet etc., the heat resistance before use and the indoor light stability are much better, so the workability of coating the UV-sensitive material layer on the support has been improved. It has great advantages such as simplified handling.

Then, 5 parts of a solution of 10 parts of 4-phenoxydichloroacetophenone dissolved in 90 parts of acetone was added to obtain 100 parts of a composition. This composition was coated on a high-quality paper having a basis weight of 100 g / m 2 so that the solid content was 20 g / m 2, and dried at 105 ° C. for 15 minutes to obtain an ultraviolet-sensitive sheet. The ultraviolet-sensitive sheet was irradiated for 10 seconds at a distance of 1 cm using an irradiator (sankyo GL-15, manufactured by Sankyo Electric Co., Ltd.) that emits ultraviolet light of 254 mμ,
The UV-irradiated surface turned green rapidly and irreversibly, and was found to be useful as a decay indicator for germicidal lamps. When, for example, leucomalachite green (4,4'bis-dimethylaminotriphenylmethane) is used instead of the compound of the present invention, coloring of the coating solution with time is large, and the coated paper is also stored under room light. A coloring tendency was observed.
