摘要 |
The present invention provides an adhesive composition having excellent strength in a cracked state, and is an adhesive composition characterized by containing a polyimide (A),a polyfunctional epoxy compound (B), an epoxy curing agent (C), and inorganic particles (D), the ratio of the polyimide (A) in a nonvolatile organic component being 3.0 wt % or more and 30 wt % or less, the ratio of the epoxy curing agent (C) in the nonvolatile organic component being 0.5 wt % or more and 10 wt % or less, and T/M being 400 or more and 8000 or less, where T is the total number of grams of the nonvolatile organic component, and M is the number of moles of epoxy groups in the nonvolatile organic component. |

1. An adhesive composition comprising a polyimide (A), a polyfunctional epoxy compound (B), an epoxy curing agent (C), and inorganic particles (D), wherein the polyimide (A) has at least one functional group capable of reacting with an epoxy group on its side chain, the polyfunctional epoxy compound (B) contains a liquid epoxy compound and a bisphenol A epoxy resin having an epoxy equivalent weight of 1000 or more and 7000 or less, the epoxy curing agent (C) is an imidazole-based curing agent,
the ratio of the polyimide (A) in a nonvolatile organic component is 17.5 wt % or more and 30 wt % or less, the ratio of the liquid epoxy compound in the nonvolatile organic component is 20 wt % or more and 50 wt % or less, the ratio of the bisphenol A epoxy resin in the nonvolatile organic component is 30 wt % or more and 70 wt % or less, the ratio of the epoxy curing agent (C) in the nonvolatile organic component is 1.0 wt % or more and 10 wt % or less, and T/M is 400 or more and 8000 or less when the total number of grams of the nonvolatile organic component is denoted by T, and the number of moles of epoxy groups in the nonvolatile organic component is denoted by M. |
