The present invention provides a photosensitive resin composition, comprising: (a) photo-polymerizable unsaturated compound, (b) hydroxyurethane compound, and (c) photoinitiator. The photosensitive resin composition can be used as photoresist coating for dry film photoresist to manufacture the electronic components, such as print circuit board and so on. Further, the (b) hydroxyurethane compound having [CC]/[NH] between 0.5 and 0.9, which increases the resolution, adhesion, and stripping ability of photosensitive resin composition for dry film photoresist, and improves the effectiveness and the quality of dry film photoresist for manufacturing printed circuit board and other electric component.

A method for making an ordered magnetic alloy includes (a) providing a thermally conductive base having opposite first and second surfaces; (b) forming a thermal barrier layer on the first surface of the thermally conductive base; (c) forming a disordered magnetic alloy layer on the thermal barrier layer, the disordered magnetic alloy layer being made from a disordered alloy which contains a first metal selected from Fe, Co, and Ni, and a second metal selected from Pt and Pd; and (d) after step (c), applying a transient heat to the thermally conductive base to cause rapid thermal expansion of the thermally conductive base, which, in turn, causes generation of an in-plane tensile stress in the disordered magnetic alloy layer.

An water/alcohol soluble electron-injection/hole-blocking composite layer contains a conjugated polymer grafted with a side chain crown ether and with pseudo-metallic state of metal-ion stabilized by the crown ether (to reduce electron-injection barrier and facilitate electron transport), and a polymer with hole-blocking function. This composite layer is able to improve the performance of an organic light emitting diode with oxygen- and moisture-stable cathode (such as Al and Au), and the performance of an organic solar cell.
