The authors develop their method (see part I, reviewed above) and construct infinitely many maximal intermediate propositional logics with the disjunction property extending the logic ASL (``anti''SL): \[ \text{Int} + \biggl( \bigl( (\neg \neg A \to A) \to A \vee \neg A \bigr) \to \neg A \vee \neg \neg A \biggr) \to \neg \neg A \vee (\neg \neg A \to A). \] Besides, a conjuncture of maximality of some logics is refuted.
