ABSTRACT:
The present invention relates to a novel compound of the formula: ##STR1## wherein R.sup.1 and R.sup.2 respectively represent hydrogen atom, lower alkyl group of 1 to 5 carbon atoms, lower alkoxy group of 1 to 5 carbon atoms or halogen atom; R.sup.3 represents hydrogen atom, alkyl group of 1 to 12 carbon atoms, alkoxyalkyl group of 1 to 12 carbon atoms, halogenoalkyl group of 1 to 12 carbon atoms, phenyl group which may be substituted or benzyl group which may be substituted; and m and n are an integer of 1 or 2; providing the R.sup.1 and R.sup.2 do not represent hydrogen atom, methyl group and methoxy group when R.sup.3 represents hydrogen atom or methyl group.
Further, the present invention relates to color developing compositions suitable for use in a recording material and pressure- or heat-sensitive recording sheet containing the novel compound of the formula (I).
