摘要： A compound capable of forming a color on contact with an electron accepting compound and useful as a chromogenic material for recording members represented by the general formula (I) ##STR1## wherein A represents an oxygen atom or a group capable of forming a lactam ring with benzen ring D; Y represents a hydrogen atom or a functional group (such as a halogen atom or a nitro group); and when A is an oxygen atom, R represents an amino, i.e., unsubstituted, group or a substituted amino group; R.sub.1 and R.sub.3, which may be the same or different, each represents a hydrogen atom, a lower alkyl group, a nitro group, an amino group, or a substituted amino group; and R.sub.2 represents a hydrogen atom or a lower alkyl group; wherein R.sub.1 and R.sub.2 or R.sub.2 and R.sub.3 may combine with benzene ring C to form a nitrogen-containing heterocyclic ring condensed therewith; and when A is a group capable of forming a lactam ring with benzene ring D, R represents ##STR2## R.sub.2 represents ##STR3## R.sub.4 ', R.sub.4, R.sub.5 and R.sub.5 ', which may be the same or different, each represents a hydrogen atom or a lower alkyl group; and R.sub.1 and R.sub.3 each represents a hydrogen atom; processes for the production thereof; and recording members containing the same.
