Abstract (en)

[origin: EP0171039A2] A solvent for the dye of pressure-sensitive recording paper which solvent has no offensive odor and is excellent regarding the color developing rate and developed color density. The solvent is characterized in that it comprises a fraction mainly containing triaryldialkanes having boiling points above 350 DEG C but not higher than 450 DEG C which is prepared by disproportionating diarylalkane or a hydrocarbon mixture comprising the same at temperatures in the range of 20 to 500 DEG C in the presence of a disproportionation catalyst, said diarylalkane having a boiling point in the range of 260 to 320 DEG C.
