PURPOSE:To suppress bluing of a coated surface, by coating a base sheet with a microcapsule liquid which comprises microcapsules containing a colorless electron-donative dye therein and further comprises a diarylaminofluoran derivative and a quinoline derivative of a specified structural formula. CONSTITUTION:A diarylaminofluoran derivative and a quinoline derivative of the formula, wherein R1 is hydrogen, a 1-8C alkoxyl, a 6-18C aryloxyl or a 7-18C aralkyloxyl, R2 is hydrogen or methyl and n is an integer of 1-10 are dissolved in a solvent. The solution thus prepared is emulsified or dispersed to prepare a coating liquid comprising microcapsules containing a color former therein, and the coating liquid is applied to a base such as a paper, followed by drying to produce a recording sheet. The amount of the quinoline derivative used is preferably 5-200wt% based on the amount of the diarylaminofluoran derivative. |
