The SU(3){sub C} - SU(3){sub L} - U(1){sub X} gauge model with two Higgs triplets (the economical 3-3-1 model) is presented. The minimal Higgs potential is considered in detail, and new Higgs bosons with the mass proportional to the bilepton mass are predicted. In the effective approximation, the charged Higgs bosons H{sub 2}{sup {+-}} are scalar bileptons, while the neutral scalar bosons H{sup 0} and H{sub 1}{sup 0} do not carry a lepton number. The couplings of the charged Higgs bosons to leptons and quarks are given. We show that Yukawa couplings of H{sub 2}{sup {+-}} to ordinary leptons and quarks are lepton-number violating. The pair production of H{sub 2}{sup {+-}} at high-energy e{sup +}e{sup -} colliders with the polarization of the e{sup +}, e{sup -} beams is studied in detail. A numerical evaluation shows that, if the Higgs mass is not too heavy, then the reaction can give an observable cross section in future colliders at a high degree of polarization. The reaction e{sup +}e{sup -} {sup {yields}} H{sub 2}{sup {+-}}W{sup {+-}} is also examined. We show that the production cross sections of H{sub 2}{sup {+-}}W{sup {+-}} are very small, much below the pair production of H{sub 2}{sup {+-}}, and, therefore, the associated production of H{sub 2}{sup {+-}} and W{sup {+-}} is, in general, not expected to lead to easily observable signals in the e{sup +}e{sup -} annihilation.
