着性に乏しい。<Prior Art> Biaxially stretched and heat-set polyester films, particularly polyethylene terephthalate films, are used for various purposes because of their excellent mechanical properties, heat resistance, gas barrier properties, chemical resistance, etc. However, polyester film has a surface resistivity value of 1014 to 1Q17 Ω/unit, and is easily charged. When used as a material for magnetic recording media or electronic materials, for example, it tends to cause problems with foreign matter adsorption, and improvements are needed. ing. In addition, polyester film has high surface cohesiveness due to crystal orientation and poor adhesion to various paints.

上に易接着性塗剤を塗布してプライマー層を設ける方法
が知られている。Conventionally known methods for imparting antistatic properties to polyester films include applying an antistatic paint and incorporating an antistatic agent into a base polymer. The most well-known type of antistatic agent is a low-molecular surfactant type. Furthermore, as a method for improving the surface properties of a polyester film, a method is known in which a primer layer is provided by applying an easily adhesive coating onto the polyester film.

を発揮することができないことがある。However, when a low-molecular-weight surfactant-type antistatic agent is included in the primer layer in order to simultaneously satisfy antistatic properties and easy adhesion, the low-molecular surfactant precipitates on the surface of the brammer, reducing easy adhesion. Conversely, the low-molecular-weight surfactant is incorporated into the network of the polymer forming the bramer and cannot move to the bramer surface, so that ion dissociation by moisture (H2O) in the air does not occur, resulting in antistatic properties. Sometimes I am unable to perform.

is particularly advantageous. The ratio of water-soluble resin to alkali metal salt is 90:10 to 50:50 by weight. If the proportion of the alkali metal salt is less than 10 wt%, a satisfactory surface resistance value cannot be obtained, while if it exceeds 50 W[%, lithium salt and potassium salt will precipitate alone, which is not preferable.
