no. 1 Embodiment approach

[0051] figure 1It is a cross-sectional view showing an example of the structure of the adhesive film according to the first embodiment of the present invention. Such as figure 1 As shown, this adhesive film 5 has an insulating film 1 , an adhesion-promoting coating 2 formed on one surface of the insulating film 1 , and an adhesive layer 3 formed on the adhesion-promoting coating 2 .

[0052] Engineering plastics are suitably used for the insulating film 1, and for example, polyester resin, aromatic polycarbonate resin, polyphenylene sulfide resin, polyimide resin, polyetherimide resin, and the like can be used. Examples of the polyester resin include polyethylene terephthalate resin, polybutylene terephthalate resin, polyethylene naphthalate resin, polybutylene naphthalate resin, Polytrimethylene terephthalate resin, polytrimethylene naphthalate resin, polycyclohexanedimethyl terephthalate resin, polycyclohexanedimethyl naphthalate resin, polyarylate resin, and the like. Am...

no. 2 Embodiment approach

[0067] figure 2 It is a cross-sectional view showing an example of the adhesive film according to the second embodiment of the present invention. The adhesive film 6 in figure 1 On the adhesive layer 3 of the adhesive film 5 composed of the insulating film 1 , the adhesion-promoting coating 2 and the adhesive layer 3 shown, a conductor adhesive layer 4 capable of bonding metal conductors is further formed.

[0068] The adhesive layer 3 has the same configuration as that of the first embodiment, but regarding the amount of the flame retardant added to the adhesive layer 3, when the conductive adhesive layer 4 is provided on the adhesive layer 3, the 100 parts by weight of the resin is not less than 120 parts by weight and not more than 200 parts by weight.

[0069] As the base resin constituting the conductive bonding layer 4 , a resin soluble in a halogen-free solvent having a boiling point of 120° C. or lower can be used. This is because if the boiling point of the solven...

no. 3 Embodiment approach

[0074] image 3 It is a sectional view showing an example of the structure of the flat cable according to the third embodiment of the present invention. The flat cable 8 is used figure 1 The adhesive film 5 shown is formed. That is, two adhesive films 5 are arranged so that the adhesive layers 3 face each other, and after a plurality of metal conductors 7 are arranged in parallel between the adhesive layers 3, the adhesive layers 3 are bonded to each other with a laminator, thereby A flat cable 8 is formed.

[0075] For the metal conductor 7 , conductive materials such as copper-based materials made of copper or copper alloys, iron-based materials made of iron or iron alloys, and aluminum-based materials made of aluminum or aluminum alloys can be used. Examples of the copper-based material include oxygen-free copper, tough copper, phosphor bronze, and the like. In addition, metal conductor 7 may be plated with metal such as Sn or Ni. image 3 The metal conductor 7 shown h...

Abstract

The adhesive film includes an insulating film, an adhesive layer provided over one side of the insulating film, and an anchor coat layer provided between the one side of the insulating film and the adhesive layer. The adhesive layer is a copolymer polyamide resin which is soluble in a solvent at 25 degrees Celsius and has a melting point of 100 degrees Celsius or more and 150 degrees Celsius or less. The anchor coat layer enhances the adhesion between the insulating film and the adhesive layer.

Description

technical field [0001] The present invention relates to an adhesive film and a flat cable using the adhesive film. Background technique [0002] A flat cable is generally a cable in which a plurality of flat conductors arranged in parallel are sandwiched between two films with an adhesive layer (hereinafter referred to as "adhesive film"), and is characterized by a thin thickness and excellent flexibility. The flat cable fully utilizes such characteristics and is widely used as an internal wiring cable of various electrical and electronic equipment such as OA equipment such as printers and scanners, computer equipment, video equipment such as flat-screen TVs, audio equipment, remote control equipment, and ultrasonic diagnostic equipment. In addition, in recent years, the electronicization of automobiles has progressed, and flat cables have begun to be popularized in in-vehicle applications. [0003] In particular, when used as an internal wiring material of an electronic de...
