An optical recording medium capable of desirable recording and playback with laser of 300 to 900 nm wavelength; and a novel compound. There is provided an optical recording medium characterized in that the ratio of change from thickness (a<1>) of recording layer at an unrecorded region of recording layer (A) to thickness (a<2>) of recording layer at a recorded region resulting from recording of the recording layer (A) with laser beams, ||[a<2>-a<1>]/a<1>||x100, is less than 25% and that the extent of change from thickness (a<1>) of recording layer at an unrecorded region of recording layer (A) to thickness (a<2>) of recording layer at a recorded region resulting from recording of the recording layer (A) with laser beams, ||a<2>-a<1>||, is regulated so as to be less than 15 nm. There is further provided a compound having a structure of six-membered ring composed of four carbon atoms and two nitrogen atoms and having a substituted or unsubstituted amino bonded thereto.
