Abstract

The invention pertains to a photosensitive element, particularly a photopolymerizable printing form precursor; a method of preparing the photosensitive element to form a printing form for use in relief printing; and, a process of making the photosensitive element. The printing form precursor includes a layer of a photosensitive composition, a digital layer that is adjacent to a side of the photosensitive layer, and a cell pattern layer that is disposed between the photosensitive layer and the digital layer. The cell pattern layer includes a plurality of features in which each feature an area between 5 to 750 square microns and is composed of an ink that is opaque to actinic radiation and transparent to infrared radiation. Since the cell pattern layer is integral with the printing form precursor, digital imaging can occur rapidly with relatively low resolution optics to form a mask without needing to also form a microcell pattern of the digital layer. The printing form precursor having the integrated cell pattern layer facilitates the preparation of relief printing forms to have a print surface suitable for printing solids with uniform, dense coverage of ink.

Abstract

Embodiments of the invention are directed to a self-sanitizing structure that includes a body having a contact surface that can be contacted by a person, along with an energy source formed as an array of addressable energy sources. The energy source generates electromagnetic radiation and direct the electromagnetic radiation through the body to the contact surface. A sensor system is coupled to the contact surface, and a controller is coupled to the energy source and the sensor system. The body scatters the electromagnetic radiation and passes it through the body to the contact surface in a manner that maintains the scattered electromagnetic radiation that reaches the contact surface as sanitizing electromagnetic radiation at or above a minimum irradiance level that neutralizes infectious agents. The sensor system generates touch data in response to the contact surface being touched, and the controller uses the touch data to control the addressable energy sources.

Abstract

The invention pertains to a photosensitive element, particularly a photopolymerizable printing form precursor; and, a process of making the photosensitive element. The printing form precursor includes a cover sheet, a layer of a photosensitive composition, and a digital layer, or infrared ablation layer, that is adjacent to a side of the photosensitive layer. A microcell patterned is embossed onto the infrared ablation layer or an overcoat/barrier layer on the infrared ablation layer. Since the microcell pattern layer is integral with the printing form precursor, digital imaging can occur rapidly with relatively low resolution optics to form a mask without needing to also form a microcell pattern of the digital layer. The printing form precursor having the integrated microcell pattern layer facilitates the preparation of relief printing forms to have a print surface suitable for printing solids with uniform, dense coverage of ink.

Abstract

A conductive structure is fabricated on a substrate (either flexible or rigid) by first printing a precursor seed layer of a conductive ink, then electroplating a highly conductive metal such as Cu or Ag onto the precursor. The plated layer has a conductivity approaching that of the bulk metal. To improve the uniformity of plating, an intervening layer of electroless metal may be deposited onto the precursor prior to electroplating. The structure may be used for applications such as coils used in a wireless power transfer system.

Abstract

In a first aspect, a polyimide film includes a dianhydride and a diamine. The dianhydride, the diamine or both the dianhydride and the diamine include an alicyclic monomer, an aliphatic monomer or both an alicyclic monomer and an aliphatic monomer. The polyimide film has a b* of 1.25 or less and a yellowness index of 2.25 or less for a film thickness of 50 μm. The polyimide film is formed by: (a) polymerizing the dianhydride and the diamine in the presence of a first solvent to obtain a polyamic acid solution; (b) imidizing the polyamic acid solution to form a substantially imidized solution; (c) casting the substantially imidized solution to form a film; and (d) drying the film.

Abstract

In a first aspect, a multilayer polymer film includes a first polymer layer having a first elastic modulus and a second polymer layer having a second elastic modulus. The first polymer layer includes a polyimide, a polyamide imide, a block copolymer of a polyimide or a polyamide imide or a mixture thereof. The second polymer layer includes a polyimide, a polyamide imide, a block copolymer of a polyimide or a polyamide imide or a mixture thereof. The first elastic modulus is different from the second elastic modulus. The first and second polymer layers are bonded by consolidation. In a second aspect, a cover window for a display includes a hard coat layer and the multilayer polymer film of the first aspect. The first polymer layer of the multilayer polymer film is the layer farthest from the display and is adhered to the hard coat layer.

Abstract

Glass articles having a thin glass layer and a top optically transparent polymeric hard-coat layer disposed on a top surface of the thin glass layer. The top optically transparent polymeric hard-coat layer may have a thickness in a range of 0.1 microns to 200 microns and a pencil hardness of 6H or more, when the pencil hardness is measured with the optically transparent polymeric hard-coat layer disposed on the top surface of the glass layer. The glass articles avoid ejection of glass shard particles from the glass article upon bending to a failure during a static two-point bend test.
