A multilayer film comprises first, second, and third layers. The first layer comprises at least one aromatic polyester, and has a loss modulus at 1 hertz and 25&#xb0; C. of at least 70 megapascals. The second layer is thermoplastic and has a loss modulus at 1 hertz and 25&#xb0; C. of less than or equal to 60 megapascals and comprises a thermoplastic elastomer and a polyamide. The third layer contacts the second layer opposite the first layer and has a loss modulus at 1 hertz and 25&#xb0; C. of at least 70 megapascals. The second layer is sandwiched between the first and third layers. A method of making the multilayer film by coextrusion is also disclosed.

Multilayer film and method of making the same

Curable compositions, cured compositions formed from the curable compositions, and articles containing the cured compositions are provided. The curable compositions include (a) a curable component that includes (1) an epoxy resin, (2) a polyamide composition, (3) a multifunctional amine compound, and (4) a multifunctional (meth)acrylate compound and (b) an optional inorganic filler. The curable composition can result in the formation of cured compositions with properties such as good tensile strength, good elongation at break, good overlap shear strength, good adhesion to substrates such as metal substrates, or a combination thereof.

Orthodontic adhesives are claimed which use polymeric filler particles with defined particle size characteristics. The particle size characteristics are controlled such that these adhesives provide comparable mechanical retention and cohesive strength of conventional orthodontic adhesives when used to bond orthodontic appliances to teeth. Because polymeric fillers are generally softer than inorganic fillers, these adhesives are easier to remove from the tooth than conventional adhesives after debonding an orthodontic appliance. Embodiments of the invention include both self-curing and two-part adhesives, packaged adhesive-coated orthodontic appliances, and methods for removing a cured adhesive from a tooth surface.

Orthodontic composition with polymeric fillers

The invention features a dental composition containing a fluorescent organic pigment, e.g. a hydroxyl substituted aryl guanamine an or a fluorescent compound encapsulated in a thermo plastic or thermo set polymer, in an amount that provides the composition with fluorescence resembling that of natural teeth.

Dental compositions with fluorescent pigment

A hybrid laminated body is provided that includes a light-transmitting support, a latent release layer disposed upon the light-transmitting support, a joining layer disposed upon the latent release layer, and a polyamide thermoplastic priming layer disposed upon the joining layer. The hybrid laminated body can further include a substrate to be processed such as, for example, a silicon wafer to be ground. Also provided is a method for manufacturing the provided laminated body.

Apparatus, hybrid laminated body, method and materials for temporary substrate support

The present invention provides a method of identifying an orthodontic adhesive on a tooth structure, the method including selectively staining a surface including the orthodontic adhesive or the tooth structure. Methods of bonding and debonding an orthodontic appliance to and from a tooth structure are also provided.

Methods of identifying orthodontic adhesives

Hardenable and hardened dental compositions, and articles including such hardenable and hardened compositions, are provided. The hardenable dental compositions include a thermally labile component including one or more thermally labile groups. Upon heating, the hardened compositions are useful, for example, for reducing the bond strength of orthodontic appliances adhered to tooth structures with the hardened compositions.
