Title:
INSULATION-COATED ELECTROCONDUCTIVE PARTICLES
Document Type and Number:
WIPO Patent Application WO/2006/090467
Kind Code:
A1
Abstract:
[PROBLEMS] To impart simultaneously excellent solvent resistance and connection reliability to insulation-coated elecroconductive particles for anisotropic conductive adhesives. [MEANS FOR SOLVING PROBLEMS] In an electroconductive particle whose surface is covered with an insulating resin layer made of an insulating resin having functional groups, the insulating resin layer is surface-treated with a polyfunctional compound having other functional groups reactive with the functional groups of the insulating resin. When the functional groups of the insulating resin are carboxyl, it is preferable to use as the polyfunctional compound a polyfunctional aziridine such as trimethylolpropane tri-β-aziridinylpropionate, tetra- methylolmethane tri-β-aziridinylpropionate or N,N-hexa- methylene-1,6-bis-1-aziridinecarboxamide. The insulating resin layer is constituted of an insulating resin comprising acrylic acid monomer units or methacrylic acid monomer units, preferably an acrylic acid/styrene copolymer.
