摘要:
Optical elements are prepared by the adhesive transfer of at least a low temperature curable (e.g., radiation or room temperature curable, preferably pressure-sensitive) adhesive layer and a conductive layer to a substrate, preferably a transparent, non-birefringent substrate such as ceramic, glass or polymeric film having, for example, a color filter array thereon. The (pressure-sensitive) curable adhesive is cured after the curable adhesive layer has been placed into contact with a final receptor surface (e.g., a color filter array on a liquid crystal panel).
摘要:
A curable pressure sensitive adhesive having long shelf stability comprising (a) at least one free radically polymerized polymer; (2) at least one cationically-polymerizable monomer; (3) a photo-activatable catalyst system for the cationically-polymerizable monomer comprising either at least one organometallic complex salt or at least one onium salt; and (4) optionally, a monohydric or polyhydric alcohol, wherein there is essentially no conversion of the cationically-polymerizable monomer of the curable pressure sensitive adhesive when stored in a manner to exclude actinic radiation, and methods of making the same.
摘要:
A method of making a multilayer all-ceramic dental appliance. A first article can be formed of a first material based on a first digital surface representation having a desired outer shape of the dental appliance. A portion of the first article can be removed to form an outer layer comprising a cavity dimensioned to accommodate an inner layer. A second article can be formed by filling the cavity of the first article with a second material. The second article can be further processed, as desired. For example, a desired inner shape can be formed in the second article. Such a desired inner shape can be based on a second digital surface representation of a dental object configured to receive the dental appliance. At least one of the first article, the outer layer, and the second article can be fired, for example, while still being coupled to a support.
摘要:
A method of making a biometric dental appliance. A first article can be formed of a first material based on a first digital surface representation having a desired outer shape of the dental appliance. A portion of the first article can then be removed to form an outer layer of the dental appliance comprising a cavity dimensioned to accommodate an inner layer. A second article can be formed by filling the cavity of the first article with a second material. The second material can have at least one different structural and/or optical property than the first material. The second article can be further processed, as desired. For example, a desired inner shape can be formed in the second article. Such a desired inner shape can be based on a second digital surface representation of a dental object configured to receive the dental appliance.
摘要:
Carbosilane-containing polymers (including oligomers) having the following structural features: greater than one repeat unit; at least four Si-arylene bonds; at least one (meth)acrylate moiety, Si—H moiety, or both; no Si—O bonds; preferably at least four silicon atoms; wherein two silicon atoms are separated by one arylene group in each repeat unit.
摘要:
Methods of manufacturing hardenable dental articles, packaged hardenable dental articles, and methods of packaging hardenable dental articles are disclosed. In various embodiments, the manufacturing may involve molding a hardenable dental material in a mold cavity that may be lined with a mold liner. The mold body may also form the package of the hardenable dental article formed within the mold cavity. In other embodiments, the hardenable dental articles may be provided in mold cavities located in sacrificial mold bodies that may be torn, stretched, softened, dissolved, etc. to release the hardenable dental articles in the mold cavities.

摘要:
A curable composition comprising a) a curable epoxy resin, a thermoplastic ethylene-vinyl acetate copolymer resin, and an effective amount of a photocatalyst for the curable epoxy resin, wherein the composition is free from hydrocarbon polyolefins and wherein the sum of a) and b) is 100 weight percent.
摘要:
A hardenable dental article including a base and at least one outer surface extending from the base, wherein at least the base and the at least one outer surface of the hardenable dental article includes a hardenable dental material; and a multi-layer polymeric film conformable release liner in contact with at least a portion of the at least one outer surface.
摘要:
Substituted saccharide compounds, dental compositions comprising substituted saccharide compounds, and methods of using dental compositions are described. In one embodiment, the substituted saccharide amide compound comprises a hydrophobic group and at least one free-radically polymerizable group with the proviso that the hydrophobic group is not bonded to the ethylenically unsaturated carbon atom of the free-radically polymerizable group. The hydrophobic group is typically bonded to a nitrogen atom of a saccharide amine residue or a carbonyl moiety of saccharide amide residue.
