Embodiment 1

[0048] Example 1: 80 g of carboxylated acrylonitrile butadiene copolymer (1072CGX, Zeon Chemicals, weight average molecular weight=204,400) was dissolved in a mixed solvent of toluene / methyl ethyl ketone (2 / 1, weight ratio) to reach 24% solids content.

[0049] Then add 75 g of bisphenol A type epoxy acrylate resin (VR60, Showa Highpolymer Co.LTD. weight average molecular weight = 7,500) dissolved in methyl ethyl ketone to a solid content of 60%, and add 45 g of 2,500 weight average molecular weight Acrylate resin [the following formula (1)].

[0050] 13g and 4g of pentaerythritol triacrylate (weight-average molecular weight=298) and 2-acryloyloxyethyl phosphate (weight-average molecular weight=196) with three acrylate functional groups were added respectively, and 4g of Benzoyl peroxide was added to a solids content of 10%.

[0051] 1.7 g of a silane coupling agent having a methacryloxy group (3-glycidoxypropyltriethoxysilane) and 19 g of nickel (Ni) particles were added to...

Embodiment 2

[0054] Example 2: An ACF composition was prepared according to the method of Example 1 except that 80 g of carboxylated acrylonitrile butadiene dissolved in a mixed solvent of toluene / methyl ethyl ketone (2 / 1 by weight) to a solids content of 25% was used Carboxylated acrylonitrile butadiene copolymer (N34, Zeon Chemicals, weight average molecular weight = 236,400) was substituted for carboxylated acrylonitrile butadiene copolymer (1072CGX, Zeon Chemicals, weight average molecular weight = 204,400).

Embodiment 3

[0055] Example 3: An ACF composition was prepared according to the method of Example 1, except that 80 g of acryl rubber (SG-80H, Nagase Chemtex, weight average molecular weight=350,000) dissolved in methyl ethyl ketone to a solid content of 26% was used instead Carboxylated acrylonitrile butadiene copolymer (1072CGX, Zeon Chemicals, weight average molecular weight = 204,400).
