RECORDING MATERIAL USING PHENOL COMPOUND

摘要

The present invention addresses the problem of providing a recording material or sheet which is excellent not only in the whiteness of non-image areas but also in the storage of non-image areas and images and which exhibits excellent color development sensitivity. In order to solve the problem, a phenol compound which is represented by general formula (I) and which is characterized by having a chromaticness index b* of 10 or less is used as a recording material. It is preferable that the phenol compound further has a brightness by Hunter of 75 or more. In general formula (I), R1 is hydroxyl or a halogen atom; p is 0 or an integer of 1 to 5; R2 and R3 are each independently a hydrogen atom or C1-6 alkyl; R4 is a hydrogen atom, C1-6 alkyl, optionally substituted phenyl, or optionally substituted benzyl; and each wavy line represents E- or Z-configuration or a mixture of both.
