Abstract

PURPOSE:To accelerate the coloring speed of a thermosensitive recording paper comprising a leuco compound and its developer, by adding a specified compound as a coloring accelerator. CONSTITUTION:2,2'-Thiodiethylbis[ 3-( 3,5-di-t-butyl-4-hydroxyphenyl )-propionate] and/or 2,4-bis( n-octylthio)-6-(4-hydroxy-3,5-di-t-butylanilino )-1,3,5-triazine are used as a coloring accelerator. In a thermosensitive recording paper provided with a recording layer containing a leuco compound (a substance which is usually colorless or light-color and which forms a color by reaction with an organic acid) and an organic acid (a developer which is usually solid but melted by heat and makes the leuco compound form a color when it comes in contact with the leuco compound), said coloring-accelerator is contained in the recording layer at a rate of 1-30wt% based on the total solid content of the recording layer.
