Abstract: A barrier film including a substrate, a base (co)polymer layer applied on a major surface of the substrate, an oxide layer applied on the base (co)polymer layer, and a protective (co)polymer layer applied on the oxide layer. The protective (co)polymer layer is formed as the reaction product of a first (meth)acryloyl compound and a (meth)acryl-silane compound derived from a Michael reaction between a second (meth)acryloyl compound and an aminosilane. The first and second (meth)acryloyl compounds may be the same. In some embodiments, a multiplicity of alternating layers of the oxide layer and the protective (co)polymer layer may be used. An oxide layer can be applied over the top protective (co)polymer layer. The barrier films provide, in some embodiments, enhanced resistance to moisture and improved peel strength adhesion of the protective (co)polymer layer(s) to the underlying layers. A process of making, and methods of using the barrier film are also described.

Abstract: The present disclosure provides a method of making an orthodontic article. The method includes (a) providing a photopolymerizable composition; (b) selectively curing the photopolymerizable composition using actinic radiation to form an article in the shape of an orthodontic article including a number of layers of at least one photopolymerized polymer; and (c) moving the article and thereby generating a mass inertial force in the uncured photopolymerizable composition. The article has a first surface, and no more than 75% of the first surface has a slope magnitude greater than 2.5 degrees. Orthodontic articles are also provided, including an orthodontic article that is prepared according to the method. Orthodontic articles having low extractable component content are further provided. The mass inertial force tends to form a coating layer of uncured photopolymerizable composition on the article, and curing the coating layer can form a surface having low slope magnitude. The low slope magnitude may be correlated to a low haze of the surface of the article.

Abstract: A curable composition is provided comprising a urethane (meth)acrylate oligomer, a urethane (urea) phosphonate ad-hesion promoter, optionally reactive diluents, and an initiator. The use of the urethane (urea) phosphonate adhesion promotor provides better ageing stability and adhesion, as measured by T-peel adhesion test, than the use of other conventional adhesion promotors.
