    摘要: Phenolic compounds of general formula (I); and recording materials characterized by containing one of them and exhibiting high light stability wherein R 1 and R 2 are each hydrogen or C 1-6 alkyl; m is an integer of 1 to 6; n is an integer of 0 to 2; p and t are each an integer of 0 to 3 with the proviso that not both are simultaneously 0; R 3 and R 4 are each nitro, carboxyl, halogeno, C 1-6 alkyl, or the like; q and u are each an integer of 0 to 2 with the proviso that when q or u is 2, R 3 S or R 4 S may be different from each other; and Y is CO or NR 5 CO (wherein R 5 is hydrogen or the like), with the provisos that when Y is CO, p is 1 and that when p is 0 and Y is NR 5 CO, n is not 0.
