The biaxially stretched polyester resin film used in the present invention is premised on being used as a material for a refrigerator door or the like in which a deep drawing process is performed on a handle portion, etc. Problems such as cracking and peeling of the resin film are likely to occur. Therefore, it is essential that the biaxially stretched polyester resin film used in the present invention has a deep drawing processability even after being laminated on a substrate. For that purpose, it is essential that the biaxially stretched polyester resin film has an optimum biaxial orientation even after being laminated on the substrate. Therefore, the biaxially stretched polyester resin film used in the present invention has a biaxial orientation degree of 0.157 to 0.160 plane orientation coefficient before being laminated on each other resin layer, and is laminated on each resin layer. After becoming the top layer of the decorative resin laminate printing resin film, or furthermore, after the decorative resin laminate printing resin film is laminated to the substrate and becoming the top layer of the decorative plate, the plane orientation coefficient close to that before the lamination.

エステル樹脂フィルムを用いることが好ましい。The plane orientation coefficient of the biaxially stretched polyester resin film of the printed resin film 1 for decorative laminate lamination after being laminated on the substrate as described above is less than that in the case of application to deep drawing. , 0.157 to 0.160. In order to obtain this preferable plane orientation coefficient after being laminated on the substrate, it is necessary to appropriately select the plane orientation coefficient, the heat setting temperature, and the heating conditions during lamination of the biaxially stretched polyester resin film before lamination. . When the oriented crystal of the biaxially stretched polyester resin film is heated above the heat setting temperature during film formation, it becomes amorphous and the adhesiveness and workability are improved, but the plane orientation coefficient is sharply reduced and the water resistance is accordingly increased. Rapidly deteriorates. Therefore, when heating and laminating with a layer such as a base resin layer to be the lower layer, or when heating and laminating also serving as embossing of the base resin layer, good adhesion and embossability with the lower resin layer can be obtained. It is preferable to use a biaxially stretched polyester resin film that has been heat-set at a temperature equal to or higher than the heating temperature required for the above.

This effect has an adverse effect in applications where moldability is required, and in addition, heating for a long time causes the crystals to become coarse and the film to become brittle. Further, when the heat setting temperature of the biaxially stretched polyester resin film is low and the plane orientation coefficient is easily reduced by heating, the adhesive layer 11 is interposed between the biaxially stretched polyester resin film and the lower resin layer. By bonding at a low temperature, a decrease in the plane orientation coefficient can be suppressed.

Further, the outermost layer of the transparent biaxially stretched polyester resin film is sequentially laminated from the bottom,
In place of polyvinyl chloride resin film which may pollute the environment by generating toxic gas and harmful substances due to incineration, it has a pattern with excellent sharpness and design, and stain resistance, A printable resin film laminated on a decorative board having excellent surface properties such as solvent resistance can be obtained. Alternatively, after the embossing process is performed on the base resin layer to form the embossed concave portions, a wiping print layer formed by filling the embossed concave portions with ink using a wiping method may be provided. Then, the printed resin film for laminating these decorative plates is laminated on a substrate such as a metal plate so that the surface orientation coefficient of the transparent biaxially stretched polyester resin film on the outermost layer is 0.157 to 0.160. By laminating it, a decorative board excellent in deep drawing formability and water resistance can be obtained. In addition, there is no toxic gas such as hydrogen chloride gas when it is incinerated and disposed of, so there is no need to worry about polluting the environment and it is also excellent in environmental conservation, including refrigerators and exterior panels for refrigerator doors, Curtain rail, wash unit,
Washing machine, system kitchen, partition, wall panel, indoor door, indoor storage, fluorescent light reflector, audiovisual equipment outer panel, microwave oven outer panel, oven outer panel,
The present invention can be suitably applied to applications having a portion to be subjected to deep drawing, such as an outer plate of a fan heater, an outer plate of a stove, and an outer plate of an air conditioner.
