We show that the Higgs resonance can be amplified in a 3-3-1 model with a m
ulti-Higgs-boson "leptophilic" scalar sector. This would allow the observat
ion of the Higgs particle in muon colliders even for Higgs boson masses con
siderably higher than the ones expected to be seen in the electroweak stand
ard model framework. [S0556-2821(99)02017-2].
