Generally, pressure-sensitive recording paper is used, for example, in US Pat.
Specification No. 7, Specification No. 2730456, No. 341
It has been known for a long time from the specification of No. 8250 and the like. Furthermore, most of the pressure-sensitive recording papers currently on the market are coated with a color-forming agent in the form of microcapsules, which is a colorless organic paint wrapped in gelatin, gum arabic, or synthetic resin capsules several microns in size. There is. However, although this type of coloring agent is excellent in terms of quality, it has the disadvantage that the manufacturing process is very complicated and it is also relatively expensive.

On the other hand, a type in which a dissolved organic dye is used as a coloring agent without being encapsulated in a capsule has a simple manufacturing process and is advantageous in terms of cost. However, pressure-sensitive recording paper coated with this type of coloring agent has the disadvantage that it easily develops color due to friction, etc., and is easily smudged. Therefore, the present inventors have conducted extensive research in order to overcome the drawbacks of the above-mentioned conventional techniques and to develop a coloring agent that is inexpensive to manufacture and causes extremely little staining without having to encapsulate the dissolved organic dye. Ta. As a result, it was discovered that the desired coloring agent could be obtained by mixing an organic dye with wax and adjusting the overall penetration within a certain range, or by further adding a zinc compound. The present invention was completed based on this knowledge.

As mentioned above, the color former composition for pressure-sensitive recording paper of the present invention has the following properties:
It contains wax and colorless electron-donating organic dye as essential components. Various types of wax can be used here, and two or more types can also be used in combination. It is preferable that at least one of them has a penetration value of 10 or less at 25°C, and one with a penetration value of 5 to 1 is particularly optimal. If the penetration is more than 10, when the resulting color former composition is used on pressure-sensitive recording paper, it will easily develop color with a slight pressure, causing stains and causing damage to displayed letters, numbers, etc. It tends to bleed easily. On the other hand, if the penetration is extremely small, color development will be difficult to occur and the color density will also be low, resulting in a lack of practicality. However, even if the "penetration degree" of the wax itself is not within the above-mentioned range, the above-mentioned disadvantages can be resolved by adjusting the penetration degree of the entire composition to 15 or less (25°C). I can do it.

As described above, in the color former composition of the present invention, the colorless electron-donating organic dye, which is a color former component, is dispersed in the wax, and at the same time, the hardness (penetration) of the entire composition is controlled within a certain range. Because of the organic dyes and the optional addition of zinc compounds, the organic dyes are less likely to be exposed from the wax encasing them under mild pressure, such as a magic rub.
, there is almost no risk of coloring and staining the recording paper. However, if you apply pressure from a pen or an impact printer, the organic dye will be exposed from the wax encapsulating it, resulting in vivid color printing.

Therefore, according to the pressure-sensitive recording paper of the present invention using the above-mentioned color former composition, it is possible to print clearly and with good sensitivity without staining the background of the recording paper. In addition, in the pressure-sensitive recording paper of the present invention, since both the color former composition and the color developer composition applied to the support are colorless, if a white pigment or the like is added as appropriate, the whiteness of the support surface can be significantly increased. This results in very beautiful recording paper.

次に本発明を実施例に基いてさらに詳しく説明する。Next, the present invention will be explained in more detail based on examples.
