    摘要: A nuclear substituted salicylic acid represented by the following general formula (I): ##STR1## (in the formula (I), R.sub.1 represents a methyl group, an isopropyl group, a tert-butyl group, a tert-amyl group, a tert-hexyl group, a tert-octyl group, an .alpha., .alpha.-dialkylbenzyl group or a nuclear substituted .alpha., .alpha.-dialkylbenzyl group; and R.sub.2 represents a tert-butyl group, a tert-amyl group, a tert-hexyl group, a tert-octyl group, an .alpha., .alpha.-dialkylbenzyl group or a nuclear substituted .alpha., .alpha.-dialkylbenzyl group) and a salt thereof are herein disclosed. The novel nuclear substituted salicylic acids and salts thereof according to the present invention have good solubility in water, organic solvents or organic polymeric compounds and, therefore, these compounds are very favorable as bactericidal and germicidal agents, stabilizers for polymeric compounds or color developing agents for recording materials.
