Abstract
Dibenzyl terephthalate and isophthalate are known compounds. The present invention is concerned with the new use of such known compounds. In a color-developing system which comprises the combination of a color-developing dye and an organic acidic substance, a higher fatty acid amide has been used as a sensitizer for such system. Unexpectedly, we have found that dibenzyl terephthalate or isophthalate is specifically useful as a sensitizer in said system.
