Abstract:
A photopolymerizable coating composition and method for polyamide substrates, wherein the photopolymerizable coating composition consists of at least one acid-functional monomer with a molecular weight less than 240 g/m, at least one reactive crosslinking monomer and at least one photoinitiator. The coating compositions of the invention have improved adhesion to polyamide substrates, and also provide faster cure times and more effective protection from environmental insults as compared to prior art compositions.
Abstract:
A biological test member, and method of making the same, is disclosed with the member including a substrate. The test member has usefulness, for example, in testing a person's blood glucose level. A first layer and a second layer of conductive metal are printed or otherwise applied on the substrate in an electrode pattern. The metal or metals are cured or sintered at a low, non-damaging temperature, such as by applying one or more pulses of a high-energy broad spectrum light. A layer of reagent may be provided on said second metal layer.
Abstract:
An ink formulation comprises a binder and at least one marking component, which comprises at least one metal oxides or oxyanion and at least one oxidizing/reducing agent, which absorbs laser irradiation between wavelengths of 780-10,600 nm, thereby causes the formulation to change color.
Abstract:

The disclosure also includes methods of coating articles with the antimicrobial polymers. The methods further include the use of adhesion-promoting reagents.
Abstract:
The present invention relates to a process for preparing an organic film on a selected zone at the surface of a photosensitive semiconductor substrate, characterized in that it comprises the following steps: (i) bringing a liquid solution comprising at least one organic adhesion primer into contact with at least said selected zone; (ii) polarization of the surface of said substrate to an electric potential more cathodic than the reduction potential of the adhesion primer used in step (i); and (iii) exposure of said selected zone to light radiation, the energy of which is at least equal to that of the band gap of said semiconductor.
Abstract:
The objective of the present invention is to provide an unexpected method of manufacturing a battery electrode and a coating die for use therein, both of which are capable of providing a high speed drying and of improving a peel strength between a collector and a compound. The manufacturing process S1 of manufacturing the battery electrode 1 includes the process of coating the compound 3 containing the electrode active material 4 and the binder 5 on the sheet collector 2 and the process of drying the compound 3 to bond the collector 2 and the compound 3, wherein in the coating process, a laser light is emitted to the interface between the compound 3 and the collector 2. Due to the above structure, regardless of the drying speed, the binder 5 contained in the compound 3 is crystallized at the interface with respect to the collector 2. As a result, the high speed drying is provided and the peel strength between the collector 2 and the compound 3 is improved.
Abstract:
A method of treating a laser-activated thermoplastic substrate having a metal compound dispersed therein is described. The substrate is contacted with an aqueous composition comprising: (i) a thiol functional organic compound; (ii) an ethoxylated alcohol surfactant; and (iii) xanthan gum. By use of the treatment composition, when the substrate is subsequently laser-activated and plated by electroless plating, extraneous plating of the substrate is substantially eliminated.
Abstract:
A process for the permanent multicolor painting of a product, e.g. a body part, includes defining a first region, a first location within the first region and a second location within the first region but different from the first location, on the surface of the product. The surface is provided with a first release layer, at least in the first region and the first release layer is exposed to electromagnetic radiation, e.g. IR radiation, at the first location but not at the second location. The surface is provided with a first layer of paint at least at the first location. The first layer of paint is fixed, at least at the first location. Alternatively, the first release layer is applied at least at the second location but not at the first location, so that an exposure to electromagnetic energy at the first location can be omitted.
Abstract:
An optical sheet, which can suitably absorb external light over a wide range and can improve a contrast, a display device, and a method for producing an optical sheet. The optical sheet is disposed on an observer side relative to an image light source and includes: a plurality of layers that control light emitted from the image light source to emit the light on the observer side, wherein at least one of the plurality of layers is an optical functional sheet layer which includes prisms being arranged in parallel along the surface of the optical sheet whereby light can be transmitted and wedge portions are arranged in parallel between the prisms whereby light can be absorbed. At least one of the plurality of layers other than the optical functional sheet layer is a light-absorbing layer.
Abstract:
In a method for producing a component (20) with a coating (24) containing nanoparticles (21), it is provided that, in order to introduce the nanoparticles (21) into the coating (24), a film (19) with the dispersely distributed nanoparticles (21) is applied to the surface (22) to be coated, which decomposes with incorporation of the nanoparticles (21) during the actual coating operation and is thereby not incorporated into the layer.
