Abstract: A bio-electrode composition contains (A) an ionic polymer material. The component (A) is a polymer compound containing: a repeating unit-a having a structure selected from the group consisting of salts of ammonium, sodium, potassium, and silver formed with any of fluorosulfonic acid, fluorosulfonimide, and N-carbonyl-fluorosulfonamide; and a repeating unit-b having a side chain with a radical-polymerizable double bond in a structure selected from the group consisting of (meth)acrylate, vinyl ether, and styrene. Thus, the present invention provides: a bio-electrode composition capable of forming a living body contact layer for a bio-electrode to enable signal collection immediately after attachment to skin and prevention of residue on the skin after peeling from the skin; a bio-electrode including a living body contact layer formed of the bio-electrode composition; and a method for manufacturing the bio-electrode.

Abstract: The present invention provides a biological electrode including an electro-conductive base material and a living body contact layer formed on the electro-conductive base material; wherein the living body contact layer includes a resin layer and particles dispersed in the resin layer, the particles being coated with gold, silver, or platinum, and a thickness of the resin layer is equal to or thinner than an average particle size of the particles. The biological electrode of the present invention is superior in electric conductivity and biocompatibility, light in weight, and can be manufactured at low cost.

Abstract: A polarization conversion element includes first light transmissive substrates and second light transmissive substrates each of which has a light incident surface and a light exiting surface and which are disposed alternately, polarization separation films, reflection films, and retardation plates. One of each of the polarization separation films and a plasma polymerization film is formed on a first surface of each of the first light transmissive substrate. Each of the reflection films is formed on a second surface of each of the first light transmissive substrate. An adhesive layer is formed on a first surface of each of the second light transmissive substrates. The other of each of the polarization separation films and the plasma polymerization films is formed on a second surface of each of the corresponding second light transmissive substrates.

Abstract: The present invention provides a sulfonium salt which can serve as a photo-acid-generator, the sulfonium salt not raising the problem of poor compatibility to a photoresist polymer having an acid-dissociable group. The sulfonium salt is represented by formula (1): wherein R1 represents a linear or branched C2 to C9 divalent hydrocarbon group; each of R2 to R5 represents a hydrogen atom or a linear or branched C1 to C3 hydrocarbon group; each of R6 and R7 represents an organic group; R6 and R7 may be linked together to form a divalent organic group; and X? represents an anion.

Abstract: The invention relates to a process for the production of sulfoalkyl-containing polymers useful as ion-exchange resins, more particularly a process for the production of sulfoalkyl-containing polymers, characterized by subjecting a polymer having side chains represented by the structural formula (1): [wherein X is a leaving group, and n is an integer of 0 to 6] to replacement of X by acylthio, and then oxidizing the acylthio groups into sulfonic acid groups. According to the process, even the leaving groups (X) contained in the polymer matrix can be nearly quantitatively replaced by sulfonic acid groups, whereby an ion-exchange resin having high ion-exchange capacity can be obtained.
