A new salicylic acid developer is herein disclosed. The salicylic acid developer is a salicylic acid derivative having the formula (I) or its metal salt: ##STR1## in which each of R.sup.13 and R.sup.15 independently is hydrogen, an alkyl group, an aryl group or a tertiary aralkyl group; R.sup.16 is an alkyl group or an aryl group; and when R.sup.15 is hydrogen R.sup.13 is a tertiary aralkyl group. An image recording process employing the image recording material is also disclosed.
