Disclosed is a transparent touch screen construction that includes a pattern of layer stacks disposed on a substrate. The layer stacks each include a transparent conductor layer and an intermediate layer positioned between the substrate and the transparent conductor layer. The intermediate layer has a refractive index that is lower than that of the transparent conductor layer and that of the substrate. The construction of the layer stacks reduces the difference in visible light transmission between the areas of the substrate covered by the stacks and the areas of the substrate left exposed by the stacks. Also disclosed are methods for reducing the visibility of a patterned transparent conductor in a touch screen by disposing an intermediate layer pattern between a substrate and a transparent conductor pattern, the intermediate layer pattern and transparent conductor pattern being coincident.

Optical component for use in a touch sensor and method of fabrication of same are disclosed. Optical component includes a multilayer optical film at least some layers of which are fabricated on the same manufacturing line and using the same manufacturing method. Each layer of the multilayer optical film is designed primarily to provide a desired associated property.

Disclosed is an implantable or insertable medical device comprising (a) a substrate and (b) a hydrogel polymer coating at a least a portion of the surface of the substrate, wherein the hydrogel polymer is adapted to render the medical device visible under magnetic resonance imaging (MRI) upon insertion or implantation of the medical device into a patient. Also disclosed is the use of such a hydrogel coated implantable or insertable medical device in a medical procedure, wherein during or after insertion or implantation of the medical device in a patient, the position of the medical device is viewed under MRI. The use of a hydrogel polymer for coating a medical device wherein the hydrogel polymer is adapted to render a medical device coated with the hydrogel polymer visible under MRI and a hydrogel polymer adapted to render a medical device coated therewith visible under MRI are also disclosed.

Implantable or insertable medical devices visible under magnetic resonance imaging

A medical device comprising a substrate and a hydrogel coating disposed over at least a portion of the substrate surface. The hydrogel coating contains an MRI contrast agent and includes inner and outer regions. The inner region comprises a first hydrogel polymer, and the outer region comprises a second hydrogel polymer that can be the same as or different from the first hydrogel polymer. The inner region exhibits more absorption upon hydration than does the outer region. Examples of hydrogel polymers include polysaccharide and polypeptide hydrogel polymers such as alginic acid, hyaluronic acid, chitin, carboxymethyl cellulose, hydroxypropyl cellulose, collagen, and gelatin, as well as salts and copolymers thereof. Upon insertion or implantation of the medical device into a patient, the hydrogel coating is differentiable from the environment surrounding the hydrogel coating under magnetic resonance imaging.

A transparent electro-conductive structure comprising a transparent substrate and formed successively thereon a transparent electro-conductive layer and a transparent coat layer, which is used in, e.g., front panels of display devices such as CRTs. The transparent electro-conductive layer is composed chiefly of i) noble-metal-coated fine silver particles having an average particle diameter of from 1 nm to 100 nm, the fine silver particles being surface-coated with gold or platinum alone or a composite of gold and platinum, and ii) a binder matrix. A transparent electro-conductive layer forming coating fluid used in the production of this transparent conductive structure comprises a solvent and noble-metal-coated fine silver particles dispersed in the solvent and having an average particle diameter of from 1 nm to 100 nm, the fine silver particles being surface-coated with gold or platinum alone or a composite of gold and platinum.
