2. Description of the Related Art Conventionally, cross-linkable resin paints such as melamine curable resin paints, isocyanate curable resin paints and oxidation curable resin paints have been used as the base material for the interior and exterior parts of automobiles. Corrosion resistance, designability,
Direct coating is applied to impart functions such as durability, weather resistance, and scratch resistance.

In order to directly coat such a base material, it is necessary to select an optimum coating method, which is troublesome, generally cannot maintain a uniform coating film thickness, and tends to cause coating defects due to coating. That the paint required for painting is consumed more than necessary, it is difficult to safely manage the work environment and safety and health of the painting, and it is difficult to collect the painted film, which causes environmental pollution. However, there is a problem in that it is not possible to give a wide range of designability because spray coating is generally performed, a finished flat plate, and a flatness and poor three-dimensional effect.

As a method using the ink jet system, a member such as an automobile is coated with an electrodeposition coating or an intermediate coating, a silver metallic coating is applied to the coated sheet, and then a water-based ink is used on the surface of the coating to read with an image scanner. Japanese Patent Laid-Open No. 10-
No. 43675.

However, the method described in this publication is designed to give a design property directly to a member having a curved surface such as an automobile by a coating film of a silver metallic paint and a pattern coating film, so that the finish appearance on the curved surface portion is improved. However, there are problems that a uniform finished pattern cannot be obtained, it is difficult to apply a pattern on a curved surface portion, and it is difficult to obtain a more diverse pattern.

EFFECTS OF THE INVENTION The film decorative material of the present invention has the above-mentioned constitution, and therefore exhibits the following effects.

It is possible to obtain a highly designed product having a colorful pattern with excellent finish.

In the film decorative material of the present invention provided with a holding base material layer, when an external matter such as pebbles or sand hits the surface of the film, energy due to impact from the surface is absorbed by the holding base material layer. Therefore, even though the surface hardness is high, the performance of the film having excellent durability can be maintained for a long period of time without causing defects such as cracking and peeling of the coating film.

Since the film surface is formed of a cured resin film, it exhibits high hardness and excellent chemical resistance, stain resistance, and abrasion resistance.

Since the decorative material of the present invention has the film structure as described above, it can be easily applied by applying an applying method suitable for each film, and defects such as wrinkles due to the attachment of the film occur. Since it does not exist, the finished appearance is excellent.

Further, a conventional melamine curable resin coating material,
Since it is not necessary to directly apply a crosslinkable resin paint such as an isocyanate-curable resin paint or an acid-curable resin paint to a substrate, a suitable method may be selected in advance depending on the coating purpose, coating film performance, designing purpose, etc. You can choose. It is possible to prevent coating defects from occurring due to painting, to prevent the paint required for painting from being consumed more than necessary, and to safely manage the work environment and safety and hygiene of painting. Further, it is easy to collect the applied coating film, which is preferable from the viewpoint of environmental pollution.
