Claim:
A recording material containing fluoran color-forming compound, the recording material containing at least one compound represented by formula (I): wherein R 1 and R 4 each independently represent a hydroxy group, a halogen atom, a C 1 -C 6 alkyl group, or a C 1 -C 6 alkoxy group; p represents 0 or any integer of 1 to 4; q represents 0 or any integer of 1 to 5; when p and q represent 2 or more, each of R 1 and each of R 4 are the same or different; R 2 and R 3 each independently represent a hydrogen atom or a C 1 -C 6 alkyl group; R 5 represents a hydrogen atom, a C 1 -C 6 alkyl group, an optionally substituted phenyl group, or an optionally substituted benzyl group; and a bond represented by a wavy line represents a geometric isomer or a mixture thereof, and, as an additive, either at least one compound represented by formula (IV): wherein R 81 and R 82 each independently represent a halogen atom, a C 1 -C 6 alkyl group, or a C 2 -C 6 alkenyl group; n1 and n2 each independently represent 0 or any integer of 1 to 4; m represents 0 or any integer of 1 to 2; and R 9 represents a C 1 -C 6 alkyl group or at least one compound represented by formula (V): wherein R 101 to R 106 each independently represent a halogen atom, a C 1 -C 6 alkyl group, or a C 2 -C 6 alkenyl group; Y represents a linear or branched, saturated or unsaturated C 1 -C 12 hydrocarbon group optionally having an ether bond, or the following formula: wherein R 11 represents a methylene group or an ethylene group, and T represents a hydrogen atom or a C 1 -C 4 alkyl group; b, c, d, e, f, and g each independently represent 0 or any integer of 1 to 4; m represents 0 or any integer of 1 to 2; and a represents 0 or any integer of 1 to 10.
