  We consider the present-day photometric and chemical properties of elliptical
galaxies, adopting the bimodal star formation scenario of Elbaz, Arnaud &
Vangioni-Flam (1995). These models utilise an initial mass function (IMF)
biased heavily toward massive stars during the early phases of galactic
evolution, leading to early Type II supernovae-driven galactic winds. A
subsequent lengthy, milder, star formation phase with a normal IMF ensues,
responsible supposedly for the stellar population observed today. Based upon
chemical evolution arguments alone, this scenario has been invoked to explain
the observed metal mass, and their abundance ratios, in the intracluster medium
of galaxy clusters. Building upon the recent compilations of
metallicity-dependent isochrones for simple stellar populations, we have
constructed a coupled photometric and chemical evolution package for composite
stellar populations in order to quantify the effects of such a model upon the
photo-chemical properties of the resultant elliptical galaxies. We demonstrate
that these predicted properties are incompatible with those observed at the
current epoch.
