Embodiment 1

[0170] (Formation of film for adhesive layer)

[0171] A polyester-based hot-melt resin (manufactured by Toyobo Co., Ltd., trade name "VYLON GM900", Tg: -15°C, melting point: 112°C) as a material component of the adhesive layer was charged into the extruder, The temperature of the resin extruded from the die was set at 180° C., extruded into a sheet, and then cooled by a cast roll to form a film for an adhesive layer having a thickness of 50 μm.

[0172] (Formation of base material layer and undercoat layer)

[0173] Add 1 part to 100 parts of polyester-polyurethane resin (coating agent: manufactured by DIC Corporation, trade name "UNIVURE NT" gravure ink medium, solid content concentration is 20% by mass) (relative to polyester- 100 parts by mass of polyurethane resin, equivalent to 2.5 parts by mass [recorded in Table 1]) isocyanurate-type hexamethylene diisocyanate (curing agent: manufactured by Asahi Kasei Chemicals Co., Ltd., trade name "DURANATE TSS-100 ", the solid co...

Embodiment 2

[0180] A laminate was produced in the same manner as in Example 1 except that no colored layer was formed and the amount of curing agent added was changed as shown in Table 1.

Embodiment 3～5

[0182] A laminate was produced in the same manner as in Example 1, except that the polyester-urethane resin was changed to the material shown in Table 1, and the amount of the curing agent added was changed as shown in Table 1.

Abstract

Disclosed is (1) a multilayer body comprising a base layer, an anchor coat layer, a colored layer and an adhesive layer or (2) a multilayer body comprising a base layer, an anchor coat layer and an adhesive layer, wherein a resin contained in the anchor coat layer and the colored layer mainly contains a polyester-urethane resin and the delamination strength at -10 DEG C is not less than 4.2 N/cm.Such a multilayer body is excellent in adhesiveness and environmental friendliness. Also disclosed are a flat cable and a member for electrical wiring, each using such a multilayer body.

Description

technical field [0001] The present invention relates to a laminate, and more specifically, to a laminate suitable for wiring members such as electrical and electronic equipment. Background technique [0002] With the spread of electronic equipment such as OA equipment, components for electrical wiring such as flexible flat cables and flat wires are widely used because they can save labor when wiring in complex equipment and prevent wiring errors. . Flat cables are usually made by sandwiching a flame-retardant adhesive layer (hot-melt polyester adhesive layer, etc.) and a flat conductor between two insulating covering layers (biaxially stretched PET film, etc.), It is formed by heat fusion or thermocompression to achieve integration. However, when the end portion of the flat cable is exposed, its strength is weak, the connector cannot be smoothly inserted and removed, and the connection with the connector is unstable due to insufficient contact pressure. [0003] Therefore...
