We characterize all entire functions \(\phi \) that maps a logarithmic Bloch-type space \({\mathcal {B}}^\alpha _{\log ^\beta }\) into another of the same kind by superposition. As consequences of our study, we obtain several results about the boundedness of superposition operators acting between \(\alpha \)-Bloch spaces, Bloch–Orlicz spaces among others.
