  The correlation functions near higher-order glass-transition singularities
are discussed for a schematic two-component model within the mode-coupling
theory for ideal glass-transitions. The correlators decay in leading order like
$-\ln(t/\tau)$ and the leading correction introduces characteristic convex and
concave patterns in the decay curves. The time scale $\tau$ follows a
Vogel-Fulcher type law close to the higher-order singularities.
