Since it consists of four layers of transparent clear paint, the number of times of painting and baking is increased compared to a two-layer or one-layer coating structure such as normal metallic paints and solid paints, which increases the number of processes. However, there was a problem in that productivity decreased accordingly.

とを知見し、この発明を達成するに至った。(Means for Solving the Problems) As a result of intensive research in order to solve the above-mentioned conventional problems, the inventors constructed a top coat consisting of a base coat containing a pigment and aluminum and a clear coat containing a finely divided pigment, The problem can be solved by using (a) anthraquinone pigment, (b) phthalocyanine, or (C) carbon as the pigment, or by using a 3-coat, 2-bake system for the top coat: base coat/transparent clear/color clear. The inventors have discovered that it is possible to do so, and have achieved this invention.
従って本発明の第１発明は電着塗料および中塗塗料を塗

とするうるし調塗膜の形成方法に関するものである。Therefore, the first aspect of the present invention is a method for forming a lacquer-like paint film, which comprises applying a base coat on a paint film that has been painted and baked with an electrodeposition paint and an intermediate coating paint, and then painting and baking a color clear coat in a wet-on-wet manner. It is related to.

法に関するものである。The second invention is characterized in that a base coat is applied on a film obtained by applying and baking an electrodeposition paint and an intermediate coating paint, a wet-on-wet transparent clear is applied and baked, and a color clear is further applied and baked. This invention relates to a method for forming a coating film.

At this time, in order to ensure transparency, the base coat contains pigment and aluminum powder, and to ensure transparency, the aluminum powder needs to be 13% by weight or less based on the solid content of the paint. . Transparency is promoted by controlling the amount of aluminum contained in the base coat to 13% by weight or less based on the solid content of the paint, and if it exceeds 13% by weight, the transparency decreases. For red and blue paint colors, the content is preferably 8% by weight or less, and for black, it is preferably 0.5% by weight or less.

より多いと、塗膜の深み感、透明感の効果が少ない。Furthermore, Color Clear consists of an acrylic polyol or a fluororesin-modified acrylic polyol and a curing agent. The curing agent is melamine or isocyanate. In addition, Color Clear contains finely divided pigments, and the particle size of the finely divided pigments is 0.01 to 0.3μ■, and for red and blue paint colors, the particle size is 0.2 to 0.3μ. desirable. The content of the atomized pigment is 0.5 to 5% by weight based on the solid content of the paint, and has the function of ensuring transparency and weather resistance. Micronized pigment is less than 0.5% by weight or 5% by weight
If the amount is larger than this, the depth and transparency of the coating film will be less effective.

Lack of storage stability. Moreover, if the diameter is larger than 0.3 μm, the weather resistance is poor.

を形成する。In one example of the method of the first invention, first, a steel plate is subjected to a chemical conversion treatment, and then electrocoated and baked at 165° C. for 30 minutes to obtain an electrocoated film. An intermediate coat is applied on top of this coating film and baked at 140°C for 30 minutes. A base coat with the function of promoting transparency is applied onto this coating film, and a color clear is applied wet-on-wet to ensure transparency and weather resistance, and then baked to form the lacquer-like coating film of the present invention. .
