匠性を奏でることとなる。As shown in Fig. 3, metallic painting using color clear is performed by forming a base layer 2 such as electrodeposition coating or intermediate coating on a steel plate 1, and applying aluminum pieces 3 and pigments 4 on this base 2. It forms a metallic base coating film 5 that contains it and does not dry out further! A color clear coating film 6 is formed at T3 (hereinafter referred to as wet-on-wet). This color clear coating film 6 contains a finely divided pigment 7 having a smaller particle size than the pigment 4 contained in the metallic base coating film 5, and this finely divided pigment 7 and the pigment of the metallic base coating film 5 4 and the aluminum piece 3 together create a deep and vivid design.

せることができる。(Problems to be Solved by the Invention) Color Clear is produced by adding melamine resin (CmN)(NH2)3) as a crosslinking agent to acrylic resin (CH, -CHCooH) and heating it as shown in Figure 4. A coating film is formed by a crosslinking reaction, and by increasing the crosslinking density, the weather resistance, scratch resistance, etc. of the coating film can be improved.

カラークリヤは耐候性、耐傷付性の点で問題があった。As a means of increasing crosslinking density, C0O
A method of increasing the blending amount of H groups or 5iOH groups has been adopted, but increasing the amount of C0OH groups will leave C0OH groups that cannot react with melamine resin, causing paint film deterioration. Ta. In other words, unreacted C0OH groups are easily separated into Co-OH by water or light, and the OH of Co-OH and the H of H2O generate new H2O, and the relatively stable C0OH becomes unstable. It becomes a CO. In the industry, it is believed that the presence of this unstable CO is the cause of progressing paint film deterioration. Therefore, conventional color clears made of acrylic-melamine resins have problems in terms of weather resistance and scratch resistance.

であると考えられている。Furthermore, color clears made of acrylic-melamine resins have the problem that even if the pigment is made into fine particles, it tends to re-condense, making it impossible to provide a bright coating film. This is because the intermolecular force of C5C00H1 or melamine is relatively small in the coating film structure formed by the crosslinking reaction of acrylic-melamine resin, so even if the pigment is atomized, it can move freely between the molecules and stay in one place. It is believed that this is due to the fact that they are easy to gather together.

ことができる。Further, since the clear coating film according to the second invention contains a fluorine-based resin, the atomized pigment is protected from ultraviolet rays by the fluorine atoms, which have a large particle size and a strong bonding force. Moreover, since the atomized pigment is appropriately dispersed between the large particle size fluorine atoms and cannot move freely in the paint, the atomized pigment does not re-condense and the dispersibility of the atomized pigment is reduced. improves. Thereby, the dispersibility of the pigment is improved, and a coating film with vivid colors can be provided.

Consists of electrodeposition and intermediate coating. Specifically, the unpainted body transported from the car body welding process is cleaned in a cleaning process to remove rust preventive oil applied during the pressing process and dust adhering to the body during the car body welding process. This cleaning process consists of hot water washing at 40 to 50°C, degreasing, and chemical conversion treatment, and its main tasks are dust removal and the formation of a chemical conversion film that improves the adhesion between the electrodeposition paint and the steel plate, which will be described later. It is a purpose. After this cleaning and chemical conversion treatment process, the body is then dried and transported to the undercoating process. The undercoating process is
For passenger cars, electrodeposition coating is generally applied, but electrostatic coating can also be applied. In this electro-deposition coating, the body is an electro-coat containing the electro-deposition paint.
Cationic electrodeposition, which is carried out by so-called full-deep coating in which the body is completely immersed in a tank, and in which the coating is carried out by applying a positive voltage to the paint side and a negative voltage to the body side, is preferable in terms of rust prevention performance. Next, the body coated with this electrodeposition is heated and dried at a high temperature of approximately 200°C to form an electrodeposition coating (
film thickness 10-25 μm).
