- the adhesive sheet comprises a base material that is a woven fabric or a non-woven fabric and a resin composition, and the resin composition described in detail below includes components (a) to (c). Contains as an essential ingredient
- epoxy resin having two or more epoxy groups in one molecule is used as component (a).
- an epoxy resin a conventionally known one can be used, and it is not particularly limited as long as it is used for a laminated board.
- bisphenol A type epoxy resin, bisphenol F type epoxy resin, bisphenol S type epoxy resin, naphthalene type epoxy resin, biphenyl type epoxy resin, phenol novolac type epoxy resin is used as component (a).
- the number of epoxy groups in the epoxy resin is not particularly limited as long as it is 2 or more per molecule, but in consideration of production, an epoxy resin having 5 or less epoxy groups is considered. It is good to use.
- the number of epoxy groups means an average of epoxy groups per molecule because epoxy resin has a molecular weight distribution.
- a particle-shaped polycarbopositimide resin is used as the component (b).
- This Examples of such polycarpoimide succinic resins include the method disclosed in JP-A-51-61599, the method of LM Alberin et al. (J. Appl. Polym. Sci., 21, 1999 (19 77). In the presence of a catalyst that promotes the carbodiimidation of an isocyanate from an organic polyisocyanate as disclosed in JP-A-2-292316, etc. One or a mixture thereof can be mentioned.
- organic polyisocyanate that is a raw material for synthesizing polycarpositimide resin
- aromatic polyisocyanate for example, aromatic polyisocyanate, aliphatic polyisocyanate, alicyclic polyisocyanate, or a mixture thereof is used.
- the organic polyisocyanate that is a raw material for synthesizing the polycarposimide resin used in the present invention is preferably an aromatic polyisocyanate from the viewpoint of heat resistance and reactivity.
- aromatic polyisocyanate means an isocyanate having two or more isocyanates directly bonded to the benzene ring in the molecule.
- the aromatic polyisocyanates preferably used are 4, 4'-diphenylmethane diisocyanate (MDI) and tolylene diisocyanate (TDI) because they are particularly versatile. ).
