Research Abstract |
The color of thermal paper turns yellow by UV light irradiation due to decomposition of color pigment. In order to resolve this low light fastness problem, a series of cinnamic acid esters that have UV light absorbing function were synthesized as new group of color developing compound. The difference of the light fastness is attributed to the molecular configuration difference in the crystalline state, which leads crystalline state molecular dimerization reaction by UV light and produces low UV absorbing compound.
