Patent Number Title Of Patent Date Issued
8088882 Polymer precursor, high transparency polyimide precursor, polymer compound, resin composition an January 3, 2012
A main object of the present invention is to provide a polymer precursor which exhibits high transmittance to a shorter wavelength range with respect to an electromagnetic wave though the polymer precursor has a part which sequences an unsaturated bond having a .pi. electron orbit and
7932340 Photo radical generator, photo sensitive resin composition and article April 26, 2011
The invention provides a radical generator, although being a self-cleavage type initiator, which is capable of suppressing volatilization of low molecular weight decomposition materials at the time of light radiation and post-baking, and leaving no low molecular weight decomposition
7528205 Photo radical generator, photo sensitive resin composition and article May 5, 2009
A photoradical generator which produces no low-molecular decomposition material but a radical during a photoradical generating process, does not generate a radical during a heating process, exists in a chemically stable state in a resulting product of a radical reaction such as a cured
7410746 Photoradical polymerization initiator, radical generator, photosensitive compound and photosensi August 12, 2008
The present invention provides a radical generator having a naphthalimide structure or a crosslinking agent and a photosensitive compound having a function as a radical generator. A photoradical polymerization initiator of the present invention comprises a compound (a) having only one
7141354 Photo radical generator, photo sensitive resin composition and article November 28, 2006
The invention provides a radical generator, although being a self-cleavage type initiator, which is capable of suppressing volatilization of low molecular weight decomposition materials at the time of light radiation and post-baking, and leaving no low molecular weight decomposition
6942817 Method of manufacturing wireless suspension blank September 13, 2005
A wireless suspension blank is made using a two-layer laminate composed of a metallic layer with the spring property and an electrically insulating layer. The first method includes a first step for working the metallic layer by the photo etching method, a second step for forming a wiring
6750148 Method of manufacturing wireless suspension blank June 15, 2004
A method of manufacturing a wireless suspension blank wherein three-layered laminate formed of a metallic layer having a spring property and a conductive layer laminated on the metallic layer through an electrically insulating layer are used. The laminate used is a laminate in which an
