からである。本発明の詳細な説明する。In the present invention, it is necessary to use 10 to 70 parts by weight of the phenol resin and 0.3 to zOffi parts of the imidazole compound represented by the above general formula to 100 parts by weight of the epoxy resin. If the phenolic resin is less than 10 parts by weight, the adhesive strength of the varnish will be poor; if it exceeds 70 parts by weight, the varnish will have poor refrigerant resistance; and if the imidazole compound is less than 0.3 parts by weight or if it exceeds 10 parts by weight This is because the effect of shortening the drying time is small when it is expressed as a quantity. The present invention will be described in detail.
