The reentrant spin-glass transition was found in the samples of solid solutions CuCr_{1.5+0.5x}Sb_{0.5-0.5x}S_{4} with x=0.34 and 0.4. The transition temperature to the spin-glass state T_{f}, determined from the bend on the temperature dependence of the initial susceptibility in an ac magnetic field, depends on the measurement frequency. It was shown that the dependence T_{f}(ω) obeys the power law 1/ω=(1/ω_{0})[T_{f}/(T_{f} - T*)]^{zν} assuming existence of the phase transition at T*. The maximum of the temperature dependence of electroresistivity was found for the sample with x=0.34 in T* region. These facts show that considered spin-glass-long magnetic order transition is the phase transition.
