Our goal in this work is to present some function spaces on the complex plane $\mathbb{C},\,X(\mathbb{C})$ , for which the quasiregular solutions of the Beltrami equation, $\bar{\partial }f(z)\,=\,\mu (z)\partial f(z)$ , have first derivatives locally in $X(\mathbb{C})$ , provided that the Beltrami coefficient $\mu $ belongs to $X(\mathbb{C})$ .
