Morphology

dilatational = dilatation (transparent) = dilat + ation + al

The adjective is formed in a regular way from the noun 'dilatation' plus '-al', meaning 'relating to dilation' or 'causing dilation'.

Etymology

Dilatational comes from the root dilate, from a Latin word that means 'spread out' or 'make wide'. So a dilatational effect is one that makes a material or object spread out or get larger.
