| abstract | NEW MATERIAL:1,4-Di(4-hydroxyphenylthio)-2,3-dihydroxybutane. n USE: A developer for leuco dyes: it is used as a color developer for heat-sensitive recording materials. n PREPARATION: The reaction of a monothiohydroquinone with 1,4-dihalogeno-2,3- dihydroxybutane under alkaline conditions gives the phenolic compound of the formula. The compound is used in combination with a leuco dye such as crystal violet lactone or 3-ethyl-6-methyl-7-anilinofluorene, preferably at a weight ratio of 1/(1W6) as a developer for a thermal sensitive recording material. The thermal sensitive recording material containing the product according to the present invention is stable without color deterioration of the developed images with time or without whitening. It has such good features as having very high image stability without descoloration of the developed images by fingerprints or oil. n COPYRIGHT: (C)1985,JPO&Japio |
