Zusammenfassung: | The adhesive compsn. is prepd. by adding and dissolving : a mixture comprising 10-50 wt.% of epoxy resin, 15-35 wt.% of polyamide resin and 5-40 wt.% of phenol resin; 15-35 wt.% of acrylonitrile; and 0.1-4 wt.% of hardening accelerating agent within methanol or mixed solution of methanol and chloroform. Pref. the hardening accelerating agent is benzyl dimethylamine, 2-methyl diimidazole or 2-ethyl-4-phenyl imidazole. The obtd. adhesive compsn. has excellent heat resistance and is useful for preparation of a flexible copper clad laminate. |
