The primary muscle used in the seated calf raise is the gastrocnemius; the secondary muscle used is the soleus. Generally-speaking, the more inner, deep-seated muscles are brought into play first in any action - which would be the soleus. Also, in a "seated" raise, I would think the gastrocnemius is not put under any potential strain: it is a very strong muscle as it needs to lift the weight of the whole body; but, then, the soleus is not put under full pressure either in this position. Nevertheless, both are used for such exercises.
