We show that models of chaotic inflation based on the 
potential and a linear non-minimal coupling to gravity, 
, can be done consistent with data in the context of Supergravity, retaining the perturbative unitarity up to the Planck scale, if we employ logarithmic Kähler potentials with prefactors 
or 
, where 
for 
or 
for 
. Focusing, moreover, on a model employing a gauge non-singlet inflaton, we show that a solution to the 
problem of MSSM and baryogenesis via non-thermal leptogenesis can be also accommodated.
