ABSTRACT:
A polymerizable composition and a method are disclosed. The composition includes a photopolymerizable monomer and a photoinitiator system for the monomer. The system, in one embodiment, is one wherein a ray of activating radiation which enters a body of the composition through a surface thereof activates the photoinitiator system and causes polymerization at each of a succession of points, the first such point being immediately adjacent the surface and subsequent points being successively farther from the surface in the direction of travel of the ray of activating radiation, the distance from the surface to the point of the succession farthest therefrom varying as a function of at least one of
