  • Patent number: 7662429
    Abstract: A laminate comprising a polyimide and a conductor layer, which is obtained by forming at least one conductor layer directly on the surface of a thermoplastic polyimide, is thermally fused by pressurizing and heating to thereby enhance the adhesion strength between the thermoplastic polyimide and the conductor layer. Thus, a laminate having an excellent adhesion strength between a conductor layer and a polyimide film can be obtained without performing any surface roughening treatment or using any adhesive metal layer.

  • Publication number: 20040024107
    Abstract: The present invention provides a polyimide intermediate transfer belt having a medium resistivity, little non-uniformity, and high insulating reliability, in which its volume resistivity at the measured voltage of 100V is within the range of 1×106to 1×1012 &OHgr;·cm because of the containing of 0.5 to 20 parts by weight of carbon black and 5 to 40 parts by weight of a plate-like or pillar-like electrically conductive powder based on 100 parts by weight of a polyimide resin. It is possible to obtain a most suitable intermediate transfer belt by the formation of a fluorocarbon resin layer including an electrically conductive material where the surface resistivity is within the range of 1×108 to 1×1013 &OHgr;/cm2.
