In this paper, we investigate the boundedness and compactness of the generalized integration operator<br />$$I_{g,\varphi}^{(n)}(f)(z)=\int_0^z f^{(n)}(\varphi(\xi))g(\xi)\ d\xi,\quad z\in\mathbb{D},$$ from Zygmund space into weighted Dirichlet type space, where $\varphi$ is an analytic self-map of $\mathbb{D}$, $n\in\mathbb{N}$ and $g\in H(\mathbb{D})$. Also we give an estimate for the essential norm of the above operator.https://scma.maragheh.ac.ir/article_251966_ddba7c527ec8fcace5d324b22d964021.pdf
