WIPO Patent Application WO/2019/074008
Kind Code:
A1
Abstract:
Provided are: an irreversible ultraviolet colour developing composition which irreversibly develops colour with a high colour development concentration as a result of being irradiated with ultraviolet, and which exhibits excellent initial state stability; an irreversible ultraviolet colour developing material which uses said composition; an ultraviolet irradiation recording material; a recording method; and a colour developing composition in which said composition develops colour. This irreversible ultraviolet colour developing composition includes compound A which is represented by formula (I), and compound B which is capable of dissolving compound A. Compound A is dissolved in compound B. X is detached from compound A and irreversibly develops colour as a result of irradiation with ultraviolet. (In formula (I): R1 to R4 each independently represent C1-4 straight-chain or branched-chain alkyl groups; Q represents oxygen, nitrogen, or sulfur; and X represents a benzoyl group or a toluenesulfonyl group.)
