Inserted. As a packaging material, in the case of small products, synthetic resin sheets are sometimes used, but in many cases, holes or depressions are formed on the inside according to the outer shape of the product, and the outside is adjusted to the dimensions of the cardboard box. Styrofoam molded articles are used. However, this polystyrene foam body has a grain boundary when polystyrene beads are foamed on the surface in the form of a turtle pattern, and the turtle pattern is transferred to a precoated steel sheet exterior member during storage or transportation of the product. However, there is a problem that the appearance is impaired. It is considered that the styrene foam pressed strongly against the coating film of the precoated steel sheet, and the coating film was deformed.

A method has been proposed in which the glass transition temperature or hardness of the top coating film on the front side is higher than that of the back coating film, (2) a method of attaching a protective film on the front side, and (3) a method of blending a large amount of filler in the coating material. . However, the method (1) cannot be applied to the case where the back side is unpainted, and even if the back side is painted, the coatability is impaired. The method (2) requires attaching and peeling of a protective film, so that manufacturing cost and processing cost are high. In the method (3), if the amount of the pigment or the like specified by the hue is exceeded, the paint becomes thick and cannot be applied.

ものにしたことを特徴としている。According to the present invention, an undercoating film of a thermosetting resin is formed on the surface of a steel sheet, and a coating mainly composed of a thermosetting polyester resin is heated and dried on the undercoating film. A precoated steel sheet having a coating film formed thereon, wherein the thermosetting polyester resin, which is a main component of the topcoat, has a molecular weight of 10,000 to 30,000, a glass transition temperature (Tg) of 5 to 40 ° C, and an extender pigment. 5 to 10 parts by weight with respect to 100 parts by weight of the resin, the primary average particle diameter D (μm) of the pigment is 0.001 <D <0.1, and the indentation hardness H (μm) of the overcoat film Is 0.8 <H <1.5.

目的の塗膜を形成することができることを見出した。BEST MODE FOR CARRYING OUT THE INVENTION Transfer patterns caused by packing materials such as styrofoam and the like are caused by the fact that the top coat is deformed by the pressure as described above, and the deformation of the coat is not recovered even after the pressure is released. It is due to remain. Therefore, the present inventors suppressed the coating film deformation due to external pressure, and as a result of examining the coating material obtained a top coat film excellent in processability,
By defining the molecular weight of the thermosetting polyester resin of the coating resin, the glass transition temperature (Tg), and the average particle size of the extender pigment contained in the overcoating film, the coating film can be formed by the effect of increasing the amount of filler in the coating film. It has been found that a desired coating film can be formed without increasing the hardness and without impairing the appearance of the coating film.

The glass transition temperature (Tg) is 5 to 40 ° C., the extender is contained in an amount of 5 to 10 parts by weight based on 100 parts by weight of the resin, and the primary average particle diameter D (μm) of the pigment is 0.001.
<D <0.1, coating indentation hardness of top coat H (μm)
Was set to 0.8 <H <1.5. When the molecular weight of the thermosetting polyester resin is less than 10,000, the workability of the precoated steel sheet is inferior because the overcoat does not elongate. And the appearance becomes poor. When the glass transition temperature (Tg) is lower than 5 ° C., the workability of the coating film is good, but the hardness is soft, so that the coating film is easily scratched.
If the temperature is higher than ℃, the workability as a precoated steel sheet cannot be maintained because the coating film hardness becomes high. In order to adjust the glass transition temperature, the molecular main chain and the side chains may be made into molecular chains that are easily thermally moved.For example, the main chain has a polyolefin group, the side chain has an alkyl group, and the like. Since there are already a large number, apply one having a suitable molecular weight.

01 <D <0.1, and the amount of the extender is 5 to 10 parts by weight based on 100 parts by weight of the resin. If the primary average particle diameter D is smaller than 0.001 μm, the cohesive force becomes extremely large, and it becomes difficult to disperse the paint varnish or solvent in use, so that it cannot be blended. Conversely, when the primary average particle diameter D is 0.1
When the particle size is larger than μm, the pigment absorbs or reflects visible light, so that appearance defects such as a decrease in coating film gloss are caused. If the amount of the extender is less than 5 parts by weight with respect to 100 parts by weight of the resin, the effect of increasing the amount of the filler is small. Specific examples of extenders that can be applied include fine particle titanium oxide, fine particle magnesia, fine powdered silica, calcium carbonate, and the like. These may be used alone or in combination of two or more.

1.5. The coating film indentation hardness is the displacement of the coating film pressed against a constant load (1 g) using a triangular indenter (115 °) at a measurement temperature of 20 ° C. The smaller the pushed displacement, the harder the coating film. This coating indentation hardness H is 0.8
If it is smaller than μm, the coating film is hard, so that pattern transfer to the coating film by the packing material can be prevented, but the workability as a precoated steel sheet cannot be maintained. Conversely, if it is larger than 1.5 μm, the workability can be maintained since the coating film is soft, but transfer of the pattern to the coating film by the packing material cannot be prevented.
The coloring pigment to be blended may be a known pigment such as titanium oxide, zinc oxide, carbon black, or chromium oxide, and may be appropriately adjusted and blended in consideration of concealing properties. The surface of the color pigment or extender may be untreated or treated with silica or alumina.
