Protection panel provided with touch input function for display window of electronic device, and manufacturing method therefor

A protection panel provided with a touch input function for a display window of an electronic device includes: a protection panel main body configured by a plastic plate having a glass plate fitting opening punched out so as to be larger than a transparent window portion, and a glass plate fitted in the glass plate fitting opening, a lower electrode sheet having a lower transparent electrode in a quadrilateral shape, and a lower circuit arranged at a periphery of the lower transparent electrode, the lower transparent electrode and the lower circuit being provided on an upper surface of a transparent resin film, the lower electrode sheet being attached to an upper surface of the protection panel main body, an upper electrode sheet having an upper transparent electrode in a quadrilateral shape, and an upper circuit arranged at a periphery of the upper transparent electrode, the upper transparent electrode and the upper circuit being provided on a lower surface of the transparent resin film, the upper electrode sheet being bonded to the lower electrode sheet at peripheral edges thereof so as to form a gap between the electrodes, and a decorative sheet having a decorative layer provided on at least one surface of a transparent resin film so as to hide the lower circuit and the upper circuit and form the transparent window portion, the decorative sheet being attached to an upper surface of the upper electrode sheet.

Scuff resistant compositions comprising ethylene acid copolymers and polyamides

Disclosed are compositions of ethylene acid copolymers and polyamides that are useful for fabricating films, sheets and molded articles for scuff and scratch resistant material and their application as decorative and protective films, comprising (1) from about 30 to about 65 weight % of a polyamide; and (2) from about 70 to about 35 weight % of a copolymer of (a) ethylene; (b) from about 5 weight % to about 15 weight % of an α,β-unsaturated C3-C8 carboxylic acid; (c) from about 0.5 weight % to about 12 weight % of at least one comonomer that is an ethylenically unsaturated dicarboxylic acid; and (d) from 0 weight % to about 30 weight % of monomers selected from alkyl acrylate and alkyl methacrylate, wherein the alkyl groups have from one to twelve carbon atoms; at least partially neutralized by one or more alkali metal, transition metal, or alkaline earth metal cations. Articles prepared from these compositions, such as films, show high toughness, good mechanical properties, excellent scratch and scuff resistance and, most importantly, good optical properties. More particularly, the compositions of ethylene copolymers and polyamides of the present invention can be used as protective coatings or layers on scuff- and scratch-exposed objects.
