Acer palmatum varieties are woodland plants, and therefore like dappled shade.

Yes, Bamboo is right. The main thing with Acers is to keep them sheltered: their leaves are easily "scorched" by wind. In amongst other plants is the best situation.

Many of the purple and green leaf forms can be planted in full sun, the variegated cultivars will prefer some shade and protection, adequate moisture at the roots is the main requirement.
