PURPOSE:To reduce a deterioration of the adhesive strength with the rise of temperature and to improve the flexibility of an attached membrane by spreading or baking a paint made by mixing a specific amount of an amino resin or a phenol resin to a polyhydroxy ether with a led-in sulfonic radical, or a mixture of such a polyhydroxy ether and a high polymer compound including an active OH radical, on a conductor. CONSTITUTION:To 100 pts.wt. of polyhydroxy ether with a led-in sulfonic radical, or a mixture of such a polyhydroxy ether and a high polymer compound including 3wt.% or more of active OH radical, 10 to 80 pts.wt. of amino resin or a paint made by mixing less then 50 pts.wt. of phenol resin to said amino resin is spread or baked on a conductor directly or through an insulating membrane. In this case, the mean molecular weight of the polyhydroxy ether and the high polymer compound is made 10000 or higher respectively. As the polyhydroxy ether with led-in sulfonic radical, YPS-007.A30, YPS-030.A30, or the like is available. As the high polymer compound including an active OH radical, phenoxy resin, polyvinyl acetal resin, or the like can be used. |
