Abstract
Various embodiments of the present invention generally relate to a light-cure and dual-cure resin that have low color and is color stable over conventional light, self and dual-cured resins. Additionally, the light-cure resin has enhanced degree of cure over conventional light-cure resins. Finally, due to the low color and enhanced color stability of the dual-cure resins, their inherent property of having lower shrinkage stress as compared to light-cure resins can now be utilized in various dental applications and other resin applications.
