The disclosure provides polymers having antimicrobial activity and articles with the polymers coated thereon. The polymers include a first pendant group comprising a first cationic component, a second pendant group comprising a nonpolar component, and a third pendant group comprising an organosilane component. The disclosure also includes methods of coating medical device articles and body fluid-receiving substrates with the antimicrobial polymers. The methods further include the use of adhesion-promoting components.

Antimicrobial-coated medical articles

An article includes a multilayer structure, such as, e.g., a touch sensor, having two opposing sides and comprising a central polymeric UV transparent substrate, a transparent conductive layer on each of the two major opposing surfaces of the polymeric substrate, a metallic conductive layer on each transparent conductive layer, and a patterned photoimaging mask on each metallic conductive layer.

Flexible touch sensor with fine pitch interconnect

Method of making a touch sensor including one or more multilayer electrodes and an underlayer disposed on a substrate. The underlayer is disposed between the multilayer electrodes and the substrate. The multilayer electrodes including at least two transparent or semitransparent conductive layers separated by a transparent or semitransparent intervening layer. The intervening layer includes electrically conductive pathways between the first and second conductive layers to help reduce interfacial reflections occurring between particular layers in devices incorporating the conducting film or electrode.

Method of making touch sensitive device with multilayer electrode and underlayer

Substantially transparent electrodes are formed on a substrate by a process including forming on the substrate, in order, a bottom high index layer, a metallic conductive layer, and a top high index layer with a conductivity of at least about 400 &#x3a9;/square; and chemically etching the bottom high index layer, the top high index layer and the conductive layer to form discrete electrodes in the metallic conductive layer.

Etching process for making electrodes

Substantially transparent electrodes are formed on a substrate by a process including forming on the substrate, in order, a bottom high index layer, a metallic conductive layer, and a top high index layer with a conductivity of at least about 400 &OHgr;/square; and chemically etching the bottom high index layer, the top high index layer and the conductive layer to form discrete electrodes in the metallic conductive layer.
