2. Description of the Related Art Keyboard switches whose surface is covered with a plastic sheet with multicolor printing have come to be used in home appliance switches and the like. Compared to traditional button-type switches, these switch keyboards are
It is beginning to be widely used because it is superior in terms of dustproofness, waterproofness, design, and the ability to greatly reduce the number of parts. The plastic sheets used for flat keyboards are mainly 100mm to 100mm thick.
200μ polyester film and polycarbonate film are used with multicolor printing on the back side. These films are used because they have good heat-resistant dimensional stability and transparency. However, since these films are hard, there is no click feeling when you press the switch, so it is difficult to check the switch directly with your fingers.Also, it requires manual effort and can be tiring if operated for a long time. Another problem is that it is difficult to use because input errors are likely to occur unless the center of operation is pressed.

非常に低いという問題がある。 In order to eliminate the above-mentioned drawbacks of hard films, thermoplastic polyurethane films with high elasticity have recently begun to be used. However, while it has the advantage of being elastic, it also has the following problems. That is, the dimensions are likely to change due to the ink solvent during printing and the heating during drying, and in the case of multicolor printing, misregistration is likely to occur, causing printing misalignment. For this reason, measures are sometimes taken to bond the urethane film with process paper and to handle the process paper while printing, but in this case as well, the process paper and urethane sheet are ultimately separated before use. Its adhesion is very low, so it may peel off partially during printing.
Similarly, there is a problem of uneven printing dimensional accuracy.
Next is the issue of dimensional stability after printing. Due to the difference in the degree of residual solvent used in printing, the degree of dimensional change of the printed sheet at room temperature or high temperature may differ, so the dimensional accuracy required for flat panel switch cover material may not be met. The problem is that the yield is very low.

由で厚みは50〜800μの範囲に規定される。 Urethane film 1 is polyester adipate type, polyester caprolactone type,
It is based on thermoplastic polyurethane resin such as polyether type, and can be made into a film by calendering, melt extrusion, or coating. Since the pattern layer 3 of the thermoplastic polyurethane resin base will be seen through the urethane film 1, it must have good transparency.
It is best to have a light transmittance of 80% or more according to the 1003 method. The surface 5 of the urethane film is preferably glossy or satin-finished. This is for the purpose of improving the printing effect, and because if the surface is glossy, it will be difficult to see the displayed content. The glossy or satin finish on the surface 5 is formed by urethane film extrusion, calendering, coating, etc. as a replica of the surface treatment of the processed paper. Hardness is
It is specified in the JIS hardness range of 60 to 100°. If it is less than 60°, it will be too soft and the texture will be poor. Further, if the angle is above 100°, it is difficult to obtain the original elastic feel, and the intended button operability is also inferior. For the same reason, the thickness is specified to be in the range of 50 to 800μ.

高い必要がある。 The adhesive layer 2 is a thermoplastic type adhesive such as a vinyl type or acrylic type adhesive, a thermosetting type adhesive such as a polyurethane type, a polyester type, an imine type, an adhesive layer made by an extrusion lamination method such as a low density polyethylene, or a pressure sensitive adhesive. Various adhesives can be selected, such as: The adhesive can be formed by coating the surface of the pattern layer 3 using the polyester film 4 as a support, by coating the urethane film 1, or by melt extrusion from a flat die during extrusion lamination. The type of adhesive, the number of layers, and the formation method can be arbitrarily selected, but since the adhesive layer 2 is formed on the upper layer of the pattern layer, it is necessary to have high transparency for the purpose of use.

Also included are metallic pigment printed layers such as Al-based. Furthermore, a metal thin film layer is also included. This metal thin film layer is, for example, a metal vapor deposition layer such as Al, and may be formed on the entire surface or partially. Further, the printed layer and the metal thin film layer may be combined in some cases.

Those having a glass transition temperature of 60°C or higher are preferred. The thickness of the plastic film is variously selected depending on the hardness and thickness of the urethane film to be laminated, but if it is less than 5 μm, it is not preferable from the viewpoint of dimensional stability, which is one of the objectives. Moreover, if it is thicker than 50 μm, the hardness is too large and button input operability is poor, which is not preferable.

Various methods can be selected, such as an extrusion lamination method in which layers are extruded and sandwiched together, a general dry lamination method, and an off-line lamination method such as a thermal lamination method in which pressure lamination is performed using heat.

The polyurethane-based printing film of the present invention comprises:
We were able to obtain various industrial benefits as described below. That is, in the case of conventional flat panel switch cover sheets using polyester films or polycarbonate films, the problem of buttons being difficult to operate due to excessive hardness has been solved.
In addition, while maintaining the elastic properties and button operability of polyurethane film, we have solved the problems associated with using polyurethane film, namely poor dimensional stability during and after printing, and large dimensional changes when heated. I was able to solve it. Furthermore, since the printing ink is sandwiched between the urethane film and the plastic film, the problems caused by ink peeling that occurred when the conventional printing ink was exposed to the outside were also eliminated. The printed film obtained by the present invention had little printing deviation, had a high design quality, and also had good button operability when incorporated into a flat panel keyboard.
