PURPOSE:To enhance storage stability by adding terpene diphenol and 1,1,3-tris(2- methyl-4-hydroxy-5-t-butylphenyl)butane or 1,1,3-tris(2-methyl-4-hydroxy-5- cyclohexylphenyl)butane as a developing compd. CONSTITUTION:As a developing compd. constituting a thermal color forming layer along with a colorless or light-colored color forming compd., for example, 2-anilin-3-methyl-6-diethylaminofluorane, terpene diphenol and 1,1,3-tris(2-methyl-4- hydroxy-5-t-butylphenyl) butane or 1,1,3-tris(2-methyl-4-hydroxy-5- cyclohexylphenyl)butane are added. In this case, the mixing wt. ratio of terpene diphenol and both compds. is pref. 1:10-4:1. |
