<p>An anisotropically electroconductive film, which has a high reliability in its capacity for conducting electricity and also a good adhesion under such an adhesive condition that the film is heated at a temperature of 130 DEG C or less for a short period of time, has a layer of an adhesive within which electroconductive particles are distributed. The adhesive is composed of a thermosetting resin composition including a base resin, a reactive compound, an organic peroxide and a reaction accelerating compound, and also the electroconductive particles incorporated into the thermosetting resin composition. The base resin is a polyacetalized resin which is obtained by acetalizing a polyvinyl alcohol. The reactive compound is at least one selected from a group consisting of acryloxy group-bearing compounds, methacryloxy group-bearing compounds and epoxy group-bearing compounds. The reaction accelerating compound is a compound which has a radically reactive group and alkali-reactive group as its end groups. An anisotropically electroconductive film, which has a good adhesion to both ITO and SiOX, has an adhesive composed of a thermoset resin composition including a base resin, a melamine resin, and the electroconductive particles. An anisotropically electroconductive film of which the adhesive can be easily controlled in its reaction rate of hardening and which has a high reliability in conductivity and also a good adhesion under such an adhesive condition that the film is heated at a low temperature and under a low pressure, has a layer of the adhesive containing electroconductive particles dispersed therein and which is composed of a thermosetting resin composition including a base resin, a polymerization inhibitor, and the electroconductive particles.</p> |
