Abstract: A composition including a polythiol having more than one thiol groups, a polyepoxide having more than one epoxide group, a catalytic amount of a second amine, and a photolatent base catalyst. The photolatent base catalyst can photochemically generate a first amine, which may be the same as or different from the second amine. A polymer network preparable from the composition, and a method for making the polymer network are also disclosed.

Abstract: Disclosed herein are aqueous dental coating compositions and methods for enhancing contrast of intraoral surfaces for 3-dimensional digital scanning. The compositions include: an aqueous solvent system; a water soluble polymer present at no greater than 5 wt. %, based on the total weight of the aqueous dental coating composition; a plurality of first particles having a first index of refraction, and a plurality of second particles having a second index of refraction different than the first index of refraction, wherein the first particles and the second particles are substantially non-absorptive in the visible range, and wherein the aqueous dental coating composition is a dispersion or a dispersion of the first particles and second particles in the aqueous solvent system can be formed by shaking the composition for 30 seconds.
