提供することである。These self-coloring pressure-sensitive recording sheets are used by writing or pressure-printing with a dot printer as a superimposed document with a high-quality paper-self-coloring pressure-sensitive recording sheet. When used as a form by overlapping with high-quality paper, desensitizing ink is applied to areas where coloring is unnecessary to prevent coloring (hereinafter, the degree to which coloring can be prevented is referred to as desensitizing effect). The main component of desensitizing ink is a desensitizer compound, most of which are almost liquid organic compounds with a molecular weight of several hundred or more and having a polyether chain in the molecule, such as polyethylene oxide or polypropylene oxide. It is blended with vehicles, binders, pigments, etc. Normally, desensitized ink printing is done using flexo, gravure, offset, or letterpress methods, and ink drying is achieved by penetrating the printing surface or paper, but the ink penetration is not instantaneous after printing, but occurs several times. A time of 10 minutes or more is required. However, printing operators can determine the amount of ink applied (amount of ink deposited per unit area, g/rrr) that will produce a desensitizing effect by writing it down with a ballpoint pen or the like immediately after printing, or by developing the color using a solvent called a desensitizing checker. The agent is dissolved and sprayed from a built-in cylinder. However, in self-coloring pressure-sensitive recording sheets, the color forming agent and color developer form a laminated or single layer to form the color forming layer, so if the ink does not penetrate into the entire layer, a desensitizing effect can be obtained. It is difficult to judge that the amount of ink is so-called appropriate. This means that if you use an organic developer that has a smaller specific surface area than an inorganic developer and fewer voids, the penetration of ink will be even slower, allowing the ink to penetrate into the entire coloring layer and achieve a desensitizing effect. It takes several hours to determine the amount. Therefore, a countermeasure is to use an excessive amount of ink, but if the amount of ink is increased, the desensitized ink may transfer from the paper roll of the printing machine to the self-coloring pressure-sensitive recording sheet, or the printed self-coloring pressure-sensitive recording sheet may be damaged. There is a problem in which the desensitized ink gradually migrates while being stacked or rolled up and stored, making it impossible to develop color in areas where color development is required. However, organic color developers have excellent properties such as liquid fluidity, color density, and image light fastness, and while they have high commercial value and are attractive from the manufacturing side, they have poor permeability and reduce the work efficiency of printing operators. Considering this, it can be said that it lacks practicality. By the way, as mentioned above, the laminated type needs to be coated twice, which requires a large amount of heat energy and electricity, and in terms of quality, it is difficult to develop color because it has two layers of microcapsules containing a color former and a color developer. The speed is slow and the concentration is low. On the other hand, the single-layer type has the great advantage of improving operability because it only needs to be coated once, and in terms of quality, the microcapsules and color developer are close to each other and coexist, so excellent color development speed and density can be achieved with low pressure. can get. Therefore, an object of the present invention is to provide a single-layer type self-coloring pressure-sensitive recording sheet that uses an organic color developer and has excellent desensitizing ink penetration.

？である。As a result of extensive experiments and research, the inventors of the present invention have developed a single-layer type ink that allows desensitizing ink to penetrate quickly even when organic color developers are used, and maintains excellent characteristics such as color development speed and density. A self-coloring pressure-sensitive recording sheet was developed. That is, the present inventors achieved the above object by including a compound represented by the following general formula (I) in a microcapsule containing a color former dissolved in a high boiling point solvent and a color forming layer mainly composed of an organic color developer. The present invention was achieved based on the knowledge that CH2-C0OR+ (I) Nap35-CH-COOR2 (In the formula, R7 and R2 represent integers having 4 to 12 carbon atoms.) The compound (I) formula of the present invention is, for example, specifically sodium dibutylsulfosuccinate, sia One member selected from sodium myrsulfosuccinate, sodium dihexylsulfosuccinate, sodium diheptylsulfosuccinate, sodium dioctylsulfosuccinate, sodium dinolylsulfosuccinate, sodium didecylsulfosuccinate, sodium diundecylsulfosuccinate, sodium dilaurylsulfosuccinate, and/or Although two types are used, particularly preferred are sodium diheptylsulfosuccinate, sodium dioctylsulfosuccinate, and sodium dinonylsulfosuccinate. The amount of compound (I) used in the present invention is 0.05 to 3 parts by weight, particularly preferably 0.1 to 1 part by weight, per 100 parts by weight of the organic color developer. If it is less than 0.05 parts by weight, the effect of improving permeability will be small, and if it exceeds 3 parts by weight, the color density will decrease. The organic color developer used in the present invention is a novolak type phenol resin, a polyvalent metal salt of an aromatic carboxylic acid, or a polyvalent metal compound of a salicylic acid resin. The basic patent for the novolac type phenol resin, which is a polycondensation of a phenol derivative and a lower aldehyde represented by formaldehyde, is Japanese Patent Publication No. 42-20144.
