[0075] Preparation Example 2: Preparation of polyurethane resin with 10 ppm ion content

[0076] 100 g of polyurethane resin (NPC7007T, NANUX) was dissolved in methyl ethyl ketone to remove ionic impurities. The ion content of the polyurethane resin measured by ion chromatography using an automatic combustion system decreased from 400 ppm to 10 ppm.

preparation example 3

[0077] Preparation Example 3: Preparation of polyurethane microbeads with 10ppm ion content

[0078] 100 g of polyurethane microbeads (MM-101-MS) were dissolved in methyl ethyl ketone to remove ionic impurities. The ion content of the polyurethane beads measured by ion chromatography using an automatic combustion system was reduced from 500 ppm to 10 ppm.

Abstract

The present invention provides an anisotropic conductive film, an anisotropic conductive film composition for the anisotropic conductive film, and a device including the anisotropic conductive film. In the anisotropic conductive film, the binder portion includes nitrile rubber resin (NBR) and / or polyurethane resin having an ion content greater than 0 and less than or equal to 100 ppm, so that the anisotropic conductive film has an ion content greater than or equal to 100 ppm. 0 and less than or equal to 100ppm ion content, so it will not cause corrosion when connected with the circuit.

Description

Technical field [0001] The present invention relates to an anisotropic conductive film, an anisotropic conductive film composition used for the anisotropic conductive film, and a device including the anisotropic conductive film. More specifically, the present invention relates to an anisotropic conductive film, an anisotropic conductive film composition for use in the anisotropic conductive film, and a device including the anisotropic conductive film, in which the anisotropic conductive film In the conductive film, the adhesive portion includes nitrile rubber resin and / or polyurethane resin having an ion content greater than 0 and less than or equal to 100 ppm, so that the anisotropic conductive film has an ion content greater than 0 and less than or equal to 100 ppm. Ion content, so it does not cause corrosion when connected to the circuit. Background technique [0002] An anisotropic conductive film refers to an adhesive film in which conductive particles such as metal particl...
