Abstract:
An object of the present invention is to provide a flame-retardant biaxially oriented polyester film which is obtained by imparting flame retardancy to a polyester film itself using a phosphorus flame retardant, and which is suppressed in the lowering of a hydrolytic resistance of the polyester film due to the flame retardant, and further suppressed in the lowering of film-forming properties and the lowering of mechanical properties due to the flame retardant, and a flame-retardant polyester film laminate formed from the same and a flexible circuit board. The present invention is obtained from a flame-retardant biaxially oriented polyester film which contains, based on the weight of the polyester film, 70 to 99.5% by weight of polyethylene terephthalate or polyethylene naphthalate, and 0.5 to 30% by weight of flame retardant particles having an average particle diameter of 0.5 to 3.0 µm and being represented by a specific phosphinate or diphosphinate, wherein the number of coarse particles having a maximum length of 10 µm or more contained in the polyester film is 10/m 2 or less.

Provided is a method for manufacturing a base material having a recessed pattern used for extending wetting of a film-forming ink while suppressing bleeding when forming a high-definition pattern, a composition used in manufacturing the base material, a method for forming an electrically conductive film, an electronic circuit, and an electronic device. The method for manufacturing the base material having the recessed pattern includes: (i) a step for applying, on a substrate (1), a composition including a polymer having an acid-dissociable group and an acid generator to form a coating (2); and (ii) a step for irradiating a localized portion of the coating (2). The method for manufacturing the electrically conductive film involves applying, on the recessed pattern formed in the exposed portion of the coating film (2), an ink for forming an electrically-conductive film, and heating the ink to form a pattern (6). The method for forming the electrically conductive film is used for providing the electronic circuit and the electronic device.
Abstract:
A cover layer (10) of a printed circuit board has a polymer film (11), a reflective composite layer (12) and an adhesive layer (13). The polymer film (11) has a melting point greater than 260°C. The reflective composite layer (12) is mounted on one side surface of the polymer film (11) and has a first reflective pigment. The adhesive layer (13) is mounted on another side surface of the polymer film (11). Also, at a range of wavelength where a reflectivity of the cover layer (10) is greater than 89%, absorption of the polymer film (11) to the same range of wavelength is less than 35%. The cover layer (10) is laminated on a printed circuit board and after surface mount technology process at a temperature ranging from 160°C to 320°C, the cover layer (10) has a reflectivity over 89% without yellowing and delamination.

A conductive ink formuation comprising metal nanoparticles and the preparation of the metal nanoparticles therein are disclosed. The ink formulation comprises at least one type of metal nanoparticles and solvent, which is to adjust the viscosity and surface tension of the ink formulation as well as the aggregation of the metal nanoparticles. The ink formulation is stable and demonstrates optimal performance, such as, improved jetting performance and good wetting property. The ink formulatin can be printed on a substrate and be further processed by sintering. The resultant film is of high conductivity. Since the annealing temperature in the present invention is relatively low, the fabrication process is compatible with plastic substrate used for flexible electronics.

A transparent component comprises a substrate (1) having an interface surface, with a pattern of electrically conductive copper (2) disposed on the interface surface with of the substrate, wherein the copper has a copper sulfide surface coating (3). It is found that copper with a suitably thin coating layer of copper sulfide has reduced visibility compared with uncoated copper, so that the metal pattern is less distracting to a viewer. The component finds application as part of a touch-sensitive display, with the substrate overlying or forming part of the display, with images on the display being visible to a user through the transparent component.
