絶縁塗料及びその製造方法並びにそれを用いた絶縁電線及びその製造方法

Japanese Patent JP5626530

B2

An insulating varnish includes a polyamide-imide resin including a repeat unit represented by Formula (1) below derived from a synthesis reaction between a resin component (X) and a diisocyanate component (Y). The resin component (X) is derived from a synthesis reaction between a diamine component including aromatic diamines including g a divalent aromatic group (R) including three or more aromatic rings, and an acid component in the presence of an azeotrope solvent. The diisocyanate component (Y) includes a 2,4'-diphenylmethane diisocyanate (Y1) and a 4,4'-diphenylmethane diisocyanate (Y2). In Formula (1), R denotes the divalent aromatic group including three or more aromatic rings, and m and n denote an integer of from 1 to 99.
