Problems solved by technology

[0004] However, depending on the type of resin parts and adherends, it is difficult to fuse with adhesives, and sufficient adhesive strength cannot be obtained even with conventional adhesives and adhesive sheets.
In addition, if coating the resin part directly, depending on the type of the resin part and the coating film, fusion may be poor, and sufficient adhesive strength between the resin part and the coating film may not be obtained, resulting in unevenness, Problems such as peeling of the coating film

Embodiment 1

[0225] (thermal transfer sheet)

[0226] (Fine Resin FR-105 (Methoxymethylated polyamide resin) manufactured by Zinichi Co., Ltd. / manufactured by Toagosei Co., Ltd., ARUFON (registered trademark) UC-3000 (Carboxyl group-containing acrylic oligomer) ( A mixture with a mass ratio of 100 / 2)) was dissolved in a mixed solvent of ethanol (EtOH) / water / isopropanol (IPA)=60 mass % / 10 mass % / 30 mass % at 60°C to prepare a 20 mass % solution (The composition for thermal transfer layer formation).

[0227] The produced composition for forming a thermal transfer layer was filtered through a nylon mesh having a mesh size of 188 μm, and then applied to a release sheet (OT-P2171: Biaxially oriented polypropylene film manufactured by Toyobo Co., Ltd.) by a bar coater. (OPP), thickness 30 micrometers), after air-drying, it further dried at 100 degreeC for 1 minute with a constant temperature dryer, and produced the thermal transfer sheet provided with the thermal transfer layer on the releas...

Embodiment 2～16、 comparative example 3～5

[0269] A thermal transfer sheet, a laminate (1), a thermal transfer sheet, a laminate (1), The structure, the coated object, and the laminated body (2) were joined, and each measurement and each evaluation were performed in the same manner as in Example 1.

[0270] In addition, Example 1 differs from the thickness of the thermal transfer layer of Examples 5-7. In addition, the same thermal transfer sheet was used in Example 1 and Example 8, but the molding temperature Tβ°C was different. In addition, Example 3 and Example 10 used the same thermal transfer sheet, but the molding temperature Tβ°C was different. In addition, the same thermal transfer sheet was used in Example 4 and Example 9, but the molding temperature Tβ°C was different. In addition, in Examples 12 to 14, the same thermal transfer sheet was used, but the molding temperature Tβ°C was different.

Abstract

The present invention pertains to a method for manufacturing a laminate, the method including a lamination step in which a heat transfer layer side of a heat transfer sheet provided with a release sheet and a heat transfer layer is laminated on at least a portion of a surface of a resin member by heat bonding, and the heat transfer layer side of the heat transfer sheet is laminated on at least a portion of the surface of the resin member. The release sheet does not have a yield point and has an elongation at break of 100-600% in a stress-strain curve measured by a tensile test at a molding temperature T [beta] DEG C in the lamination step.

Description

technical field [0001] The present invention relates to a method for producing a laminate, a method for producing a coated product, a method for producing a bonded structure, a thermal transfer sheet, and a laminate. Background technique [0002] In recent years, in parts of transportation equipment such as railway vehicles, airplanes, ships, and automobiles, electronic equipment, and housing equipment, resins that are lightweight and excellent in impact resistance have been used, and adherends of various materials have been bonded to the surfaces of these components. . In addition, a coating film having various functions may be formed on a resin member. [0003] In addition, when joining a resin member to an adherend such as metal and other resins, sufficient adhesive strength is required. In addition, when coating a coating film on a resin member, various resins are used as a base polymer for the coating film, and in order to prevent peeling of the coating film, it is re...
