摘要:
Hardenable and hardened dental compositions that include radiation-to-heat converters, and articles including such hardenable and hardened compositions, are provided. Upon irradiating, the hardened compositions increase in temperature, which can be useful for reducing the bond strengths of orthodontic appliances adhered to tooth structures with the hardened compositions.

A multilayer article is provided comprising a metallic nanoparticle layer and a reflective film layer. The article may be marked on exposure to incident light.
摘要:
The present invention is directed to an article comprising a thermoplastic polymer film and a discontinuous metallic nanoparticle coating, of an average size less than 100 nm, and the process for preparing the same. The coated film may be further stretched or shrunk to shift the absorbance peak maximum to the desired degree. The coating is formed by depositing a discontinuous layer of metallic nanoparticles by a physical vapor deposition method.
摘要:
A protective film includes a base layer and a wear layer, the wear layer comprising a UV cured hardcoat resin, and the UV cured hardcoat resin comprising surface modified silica nanoparticles. The protective film may comprise a pressure sensitive adhesive for adhesion to a floor. The protective film may be used, for example, as a protective floor finish.

Nonwoven electret fibrous webs including randomly oriented discrete fibers comprising electret fibers, the webs including a multiplicity of non-hollow projections extending from a major surface of the nonwoven electret fibrous web, and a multiplicity of substantially planar land areas formed between each adjoining projection in a plane defined by and substantially parallel with the major surface. In some exemplary embodiments, the randomly oriented discrete fibers include multi-component fibers having at least a first region having a first melting temperature and a second region having a second melting temperature, wherein the first melting temperature is less than the second melting temperature. At least a portion of the oriented discrete fibers are bonded together at a plurality of intersection points with the first region of the multi-component fibers. In certain embodiments, the patterned air-laid nonwoven electret fibrous webs include particulates. Methods of making and using patterned electret fibrous webs are also disclosed.
