組成を次に示す。 FIG. 1 is a cross-sectional view showing the high-gloss coating structure according to this example, in which 1 is the substrate (steel plate), 2 is the electrodeposition coating film, 3 is the intermediate coating film, 4 is the top coating film, and 5 is the top coating film.
is the re-top coated film. Here, the re-top coating film 5 is formed by applying a re-top coating paint to a thickness of 30 μm and then baking it at 140 to 160°C for 15 to 30 minutes. The composition of the paint is shown below.
再上塗り塗料
樹脂分（メラミン・アルキド） 72重量％
グリーン顔料 １重量％
ブルー顔料 １重量％
ブラツク顔料 １重量％以下

このように再上塗り塗料は、従来の項に示した
上塗り塗料の組成と比較すれば明らかなように、
上塗り塗料より樹脂分を多くするとともに顔料を
少なくしてある。このとき再上塗り塗料に用いる
顔料は上塗り塗料の顔料と同色系で親和性の高い
ものが良いが、できれば同一の顔料を使用するの
が好ましい。これにより上塗り塗装膜の色が再上
塗り塗装膜をとおして表現されるので色に深みが
感じられ、高級感を表現することができる。Re-top coating resin content (melamine/alkyd) 72% by weight Green pigment 1% by weight Blue pigment 1% by weight Black pigment 1% by weight or less Titanium (pigment) 1% by weight Solvent 25% by weight In this way, re-top coating paint is conventionally As is clear from the comparison with the composition of the top coat shown in the section,
It contains more resin and less pigment than top coat paint. At this time, the pigment used in the re-top coating should preferably have the same color and high affinity as the pigment in the top coating, but it is preferable to use the same pigment if possible. As a result, the color of the topcoat film is expressed through the re-topcoat film, giving a sense of depth to the color and creating a sense of luxury.

120℃で10〜15分乾燥することにより行えばよい。 When forming such a re-top coat film, by water-sanding the expression of the top coat film, the surface of the re-top coat film can be brought close to a mirror surface.
It is possible to further increase the gloss. In this case, use water-resistant paper of #800 to #1000 (JIS
R 6253), sand the surface by 3 to 8 μm to make it smooth, then wash thoroughly with water and
This may be done by drying at 120°C for 10 to 15 minutes.

例を上塗りクリヤーの組成とともに以下に示す。 Although the above embodiments show examples of solid coating, the present invention can also be applied to metallic coating. An example is shown in FIG. 2, in which a re-top coating film 5 is formed on top coating film 4 consisting of top coating base 4a and top coating clear film 4b. In this case, the paint used for the re-top coating film 5 may be approximately the same as that used for the top-coat clear film 4b which does not contain pigments, but it is preferable to add some additives. An example of the composition of this re-top coating (clear) is shown below along with the composition of the top coat clear.
