The range of the black particulate and the black particulate dispersion liquid and the black reverse clipping film and black reverse clipping

摘要

PROBLEM TO BE SOLVED: To provide inexpensive black microparticles excellent in blackness and light-shielding ability and also slight in environmental burden, and to provide a black microparticle dispersion, black light-shielding film and a black light-shielding film-clad base material, respectively.;SOLUTION: The black microparticles are 1-200 nm in average size, being characterized in comprising copper-tin alloy microparticles in the form of a mixture of spherical, plate-like, cubic and rodlike ones.;COPYRIGHT: (C)2008,JPO&INPIT
