DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a laminate, and more particularly to a laminate having a transparent film interposed between two transparent plates and suitable for use in laminated IIK with a good appearance. The present invention relates to a laminate suitable for obtaining a laminated window with a more advanced function.

BACKGROUND OF THE INVENTION Laminated glass windows are used for transparent openings that require safety, such as windows of automobiles, trains, airplanes, etc., or some building windows. The basic structure of a laminated window is that a thermoplastic resin layer is sandwiched between transparent bodies such as glass plates, or a film is further interposed to give the laminated window additional functionality. . For example, a method that uses a transparent film with excellent mechanical strength to prevent scattering, a method that uses a transparent conductive film to prevent condensation, a method that allows visible light to pass through but near infrared rays. A method has been proposed in which a film with a selective light transmittance function that is difficult to pass through is interposed.

As the thickness of the film is made thinner, the transparency of the laminated window is good, but when looking at the reflection from the surface of the laminated window, there are small irregularities in the bones and the image itself appears distorted, so it is not practical. Ivy is something that cannot be served. On the other hand, there is generally a method of applying thin film processing to the film surface in order to impart functionality to the surface of the film, but thin sliding processing is often done in a vacuum container, and its processability and productivity (e.g. From the point of view of continuous production (continuous production), the thinner the film, the better.

There is another effect of laminating the thermoplastic resin layer, heat-absorbent film, and thermoplastic resin layer in advance. When handling heat-shrinkable film by hand, no matter how carefully you handle it, the film is not under uniform tension, resulting in folds and unevenness on the surface of the film, and thin canal-like lines at the boundaries of the unevenness. Occur. These streaks and folded marks are not a big concern when the heat-shrinkable film is used for laminated windows in its untreated state, but since the heat-shrinkable film imparts functionality, Processing 1 For example, if a product has been processed to have a light selective transmittance function, it has the disadvantage that streaks or broken marks that occur on the processed surface are likely to deteriorate and spread during durability tests. are doing.

The laminate can be manufactured by laminating a sheet of thermoplastic resin from an extrusion die on both sides of a heat-shrinkable film, or by releasing a sheet of thermoplastic resin on one side. There is a method of laminating the film onto the thick surface of a heat-shrinkable film while unwrapping it from the already rolled film.

If the thickness of the heat-shrinkable film is thin, the embossed surface of the thermoplastic resin may transfer the unevenness caused by the embossing onto the heat-shrinkable film, making it difficult to obtain a good appearance.

The surface of the thermoplastic resin in contact with the transparent plate is preferably embossed. This is because when a thermoplastic resin with a non-embossed surface comes into contact with a transparent plate, it is difficult to form an even layer without forming bubbles. Also, in such cases, it is possible to prevent the generation of bubbles by pouring another resin with liquid adhesive properties, but this increases the number of manufacturing steps for the laminated window, which results in an increase in cost. From the above, embossing is also good because it eliminates the generation of air bubbles and facilitates degassing.

A laminate in which a thermoplastic resin, a heat-shrinkable film, and a thermoplastic resin layer are sequentially laminated is coated with a release film in order to prevent the thermoplastic resins from adhering to each other when rolled. It is preferable to lower the viscosity of the thermoplastic resin by laminating it on the thermoplastic resin, or by adhering a powder of aluminum (hydrogen oxide) to the thermoplastic resin.

Representative, Tokusue Tomo: Column 6 of "Detailed Description of the Invention" of the specification to be amended in No. 58, contents of the amendment (1) Add the following sentence after line 9 of No. 14Q of the specification. [More preferably, it satisfies 100≧d>10, particularly preferably 80≧d≧10. From the viewpoint of productivity when reducing film cost or adding functionality, it is preferable that the thickness of the RI film is as small as possible. Furthermore, it is not preferable for the film to be too thick for rounding to ensure safety in the event of a collision, which is one of the characteristics required for laminated windows. If the film is too thick, it will be difficult to absorb the energy caused by breaking the glass and deforming the thermoplastic. (2) Add the following sentence to the 5th line of page 23 of the specification. Comparative Example 6 In Example 5, the film was sandwiched and laminated from both sides with polyvinyl butyral films to prepare a material DK. Thickness 2 MO glass plate top K111 layer, polyvinyl buteral foil A, wrinkled film. A polyvinyl butyral film and a 2 sm thick glass plate were laminated. Otherwise, the nine laminates were manufactured under the same conditions, and the appearance of the nine laminates was somewhat uneven, and the evaluation was △.
