摘要： PURPOSE:To obtain a pressure-sensitive recording body being excellent in the property of color development and the property of fastness of a colored image, free from a coloring stain and the like and also excellent in desensitization appropriateness, by using a specific diarylmethane compound in a state of being contained in a specific microcapsule and also by combining it with a specific coloring agent. CONSTITUTION:A pressure-sensitive recording body utilizes the color reaction of a colorless or light-colored basic material with a coloring agent. In this case, at least one kind of diarylmethane compound out of the ones expressed respectively by general formulas shown separately is used as a basic dyestuff. In each of the formulas, R1 to R4 denote alkyl groups of C1 to C5 or the like respectively, R5 and R6 hydrogen atoms or the like and R7 an alkoxy group of C1 to C4 or a benzyl group which may be replaced by a halogen atom, or the like, respectively. The basic dyestuff is contained in a synthetic macromolecular microcapsule of which the average particle size is 3 to 15mum and the average film thickness 0.1 to 0.7mum. As for the coloring agent, an active viscosity mineral containing a silicon oxide (SiO2) of 65 to 80wt.% is used.

CONSTITUTION:In a pressure-sensitive recording body, a color reaction of a colorless or light-colored basic dye with a color developer is used. In this invention, as the basic dye, a diarylmethane compound shown by a separate general formula is used. In addition, the basic dye is encapsuled in a microcapsule made of a polyurethane resin and/or a polyurea resin with a 3-15mum average particle diameter and a 0.1-0.7mum average film thickness. Furthermore, as the color developer, an activated clay mineral containing 65-80wt.% silicon oxide is used. In the separate general formula, R1-R4 each represents a 1-5C alkyl group or benzyl group, R5 and R6 each represents a hydrogen atom or the like, and R7 represents a 1-5C alkyl or the like.
