The SLV and ASLV that preceded PSLV were solid-propellant based rockets, but it was actually GSLV (Geosynchronous Satellite Launch Vehicle), not PSLV, that was the first to extensively use liquid stages. PSLV does use a combination of solid and liquid stages, but it wasn't the first Indian rocket to incorporate liquid propulsion.
