Some class of anisotropic elliptic equations with non-power nonlinearities in space $\mathbb{R}_n$ is considered $$ -\sum\limits_{\alpha=1}^{n}(a_{\alpha}(\mathrm{x},u_{x_{\alpha}}))_{x_{\alpha}}+a_0(\mathrm{x},u)=F_0( \mathrm{x}).$$ The theorem of existence of solutions in local Sobolev–Orlicz spaces without restrictions on data growth on infinity is proved. Conditions on structure of an equation, sufficient for uniqueness of solutions, without restrictions on its growth on infinity are found. The power estimate characterizing the behavior of the solution at infinity is installed. The continuous dependence of solution on right side of solution is proved.
