Photographic recording material containing a precursor of a photographically-active compound

Precursor compounds from which photographically-active compounds are released with a time delay correspond to the following general formula wherein A represents the residue of a compound which undergoes oxidative coupling; X represents -O-, -S- or -NR1-; Y represents a releasable group which may consist of or contain the residue of a photographically-active compound; and R represents a group for controlling the kinetics of release. Advantageous pictorial properties (inter-image effect, edge effect, modulation transfer function) are obtained with compounds according to the present invention if the photographically-active residue is the residue of a development inhibitor.
