  We study the irreversible adsorption of spherical $2AnB$ patchy colloids
(with two $A$-patches on the poles and $n$ $B$-patches along the equator) on a
substrate. In particular, we consider dissimilar $AA$, $AB$, and $BB$ binding
probabilities. We characterize the patch-colloid network and its dependence on
$n$ and on the binding probabilities. Two growth regimes are identified with
different density profiles and we calculate a growth mode diagram as a function
of the colloid parameters. We also find that, close to the substrate, the
density of the network, which depends on the colloid parameters, is
characterized by a depletion zone.
