$\eta_c$-meson production and two-photon decay at the NICA energies was studied. Square of the amplitude of the above process was found and the signal-background ratio was constructed. The process of diphoton birth (direct and with fragmentation) was chosen as the background. Special attention was paid to the influence of experimental cut on transverse momentum on the calculation results.The diphoton decay of the $\pi_0$ meson tried out as the background, and the signal-background ratio was evaluated in this case as well.
