Title:
INSULATION-COATED ELECTROCONDUCTIVE PARTICLES
Document Type and Number:
WIPO Patent Application WO/2005/017923
Kind Code:
A1
Abstract:
Fur the purpose of imparting simultaneously both excellent solvent resistance and high conduction reliability to insulation-coated electroconductive particles suitable for electroconductive particles of anisotropic electroconductive adhesives, electroconductive particles covered with carboxyl -bearing insulating resin layers are subjected to surface treatment of the insulating resin layers with a polyfunctional aziridine compound. The polyfunctional aziridine compound includes trimethylolpropane tri-β-aziridinylpropionate, tetramethylolmethane tri-β-aziridinylpropionate, and N,N-hexamethylene-1,6-bis-1-aziridinecarboxamide. The insulating resin layers are preferably made of an insulating resin comprising acrylic acid monomer units or methacrylic acid monomer units, specifically an acrylic acid/styrene copolymer.
