Abstract: An orthodontic article is described comprising the reaction product of a free-radically polymerizable resin; a first free-radical photoinitiator having sufficient absorbance at a first wavelength range; and a second free-radical initiator selected from a second photoinitiator having sufficient absorbance at a second wavelength range, wherein the second wavelength range is different than the first wavelength range, or a thermal free-radical initiator. In some embodiments, a 1 g/liter acetonitrile solution, at a pathlength of 1 cm, has an absorbance of greater than 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, or 0.10 at a wavelength of the first wavelength range when measured with a spectrophotometer. In some embodiments, the first free-radical photoinitiator exhibits a maximum absorbance at a wavelength of the range of 370-380 nm or 320-330 nm and/or comprises photoinitiator groups selected from acyl phosphine oxide or alkyl amine acetophenone. Also described are photopolymerizable compositions and methods.

The curable films are flexible and free-standing, and have a complex viscosity of greater than 100,000 poise (10,000 Pascal seconds) at 25° C. and less than 100 poise (10 Pascal seconds) at 85° C., prior to setting. The set film has an adhesive shear strength of greater than 100 Newtons per square centimeter (N/cm2) to a glass substrate when measured according to the Shear Adhesion Test Method. The reactive composition includes an ethylenically unsaturated polyester-containing oligomeric composition that is the reaction product of a saturated, amorphous co-polyester polyol and a compound with a terminal polyol-reactive group and a terminal ethylenically unsaturated group, a (meth)acrylate functional material, and at least one initiator.
