Abstract: Anti-reflective assemblies comprise: a high dielectric permittivity substrate comprising a ceramic and a nonporous multilayer anti-reflective film contacting or adhesively bonded to the substrate. The nonporous multilayer anti-reflective film comprises sequential first, second, and third layers of sequentially decreasing dielectric permittivity. Each layer comprises a respective polymer matrix and filler particles.

Abstract: A tape includes an electrically conductive adhesive first layer having opposite outermost first and second major surfaces. The first layer includes an electrically conductive porous medium and an adhesive disposed in, and extending through a thickness of, the porous medium to define at the first major surface, first regions of exposed adhesive and first regions of exposed porous medium and to define at the second major surface, second regions of exposed adhesive and second regions of exposed porous medium. The second major surface has a higher fraction of exposed porous medium than the first major surface. The porous medium can be a nonwoven fabric and the regions of exposed porous medium can be regions of exposed fibers.

Abstract: Electrically conductive masking tapes include an electrically conductive backing and an electrically conductive pressure sensitive adhesive layer. The pressure sensitive adhesive contains an acrylate-based copolymeric matrix, a crosslinker, an electrically conductive filler, and at least one antioxidant. The acrylate-based copolymeric matrix is the reaction product of a polymerizable mixture including at least one first alkyl(meth)acrylate monomer with a homopolymer Tg of less than −50° C., and at least one hydroxyl-functional alkyl(meth)acrylate with a homopolymer Tg of less than −10° C. The electrically conductive tape is capable of being laminated to and cleanly removed from a substrate surface, after being subjected to harsh conditions such as plasma vapor deposition conditions.
