Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel pearlescent finish decorative film material used for exterior or interior of automobiles and the like.

[0002]

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.

Further, as a pressure-sensitive adhesive sheet using a pigment having a pearlescent luster, a pressure-sensitive adhesive layer obtained by adding 5 parts by weight of a pearl pigment to 100 parts by weight of an acrylic adhesive is provided on the surface of a transparent vinyl chloride resin film. A toning PVC-based pressure-sensitive adhesive sheet is known (Japanese Patent Laid-Open No. 63-75081). However, the color tone of the pearl depends on the pearl pigment contained in the pressure-sensitive adhesive layer, but if the amount of the pearl pigment mixed in the pressure-sensitive adhesive layer is too large, the color tone and the adhesive strength are deteriorated, so the addition amount of the pearl pigment is set to 30% or less. For this reason, the hiding property of the pressure-sensitive adhesive layer with respect to the adherend becomes insufficient, and the colors of the adherend appear to be mixed, so that the original pearl tone is impaired.

Also, a paste 1 made of vinyl chloride resin
There is also known a pearl-like adhesive sheet in which a colored adhesive layer is provided on a resin film obtained by adding 10 parts by weight of a pearl pigment to 00 parts by weight (JP-A-63-46285). This is because the pearlescent pigment is light transmissive,
The hiding property is improved so that the color of the adherend to which this is attached does not affect the color of the adhesive sheet. However, since such a pearl pigment cannot provide sufficient hiding power, a resin film having a semi-transparent property is used, and a pressure-sensitive adhesive layer having a translucent or opaque material mixed with a coloring agent is used. Therefore, when attached to an adherend,
Even if the hiding property to the adherend is obtained, the hiding property of the resin film is insufficient, so the color of the colorant contained in the adhesive layer appears to be mixed, so the color tone is different from the original pearl tone. Becomes Further, since the resin film containing the pearl pigment is the outermost layer, there is a problem that the weather resistance is poor.

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 pearl luster excellent in finishability.

In the film decorative material of the present invention provided with a holding base material layer, when an external object 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 the application method suitable for each film, and defects such as wrinkles occur due to the attachment of the film. Since it does not exist, the finished appearance is excellent.

In addition, conventional melamine curable resin paints,
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.
