Abstract

An object of the present invention is to provide a novel phenolic compound, and a recording material containing the same, which is excellent in storage stability. The object can be achieved by a phenolic compound represented by the formula (I):
[wherein m represents an integer of 0 to 2; R¹ and R² each independently represents a C1-C6 alkyl group or a C1-C6 alkoxy group; p and q each independently represents an integer of 0 to 4; t and u each independently represents 0 or 1 and do not simultaneously represent 0; and X represents a group represented by any of the formulas (II) to (VII):
(wherein R³, R⁴, R⁵, R⁶, R⁷, R⁸, R⁹, R¹⁰ and R¹¹ each independently represents a hydrogen atom or a C1-C6 alkyl group; a represents an integer of 1 to 6; b represents an integer of 0 to 4; and c represents an integer of 0 to 6)] and a recording material containing the same.
