PROBLEM TO BE SOLVED: To give an insulation coated conductive particle suitable for a conductive particle of an anisotropic conductive adhesive having both superior solvent resistance and conduction reliability. SOLUTION: An insulating resin layer of the insulation coated conductive particle whose surface is coated with the insulating resin layer comprising an insulating resin having a carboxyl group, is surface-treated with multifunctional aziridine compound. The aziridine compound used is, for example, trimethylolpropane-tri-β-aziridinyl propionate, tetramethylolmethane-tri-β-aziridinyl propionate, or N, N-hexamethylene-1, 6-bis-1-aziridine carboxamido. The insulating resin layer is preferably constructed from an insulating resin having an acrylic acid monomer unit or methacrylic acid monomer unit. Concretely, acrylic acid-styrene copolymer is preferable. COPYRIGHT: (C)2005,JPO&NCIPI |
