Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to decorative moldings used for protection and decoration on the sides of automobiles, etc.

(Prior Art) In recent years, plastic decorative moldings have been attached to the sides of automobiles to protect the vehicle body.

Due to its purpose, this molding is usually pasted in a substantially straight line from the front side (front fender) to the rear side (rear fender) of the car body, so the plastic extrusion Molded products are conveniently used.

However, since this type of exterior molding is exposed to sunlight, rain, etc., it must have excellent weather resistance, and for this reason, colored plastics containing weather-resistant pigments such as carbon black are usually used. It is molded from. On the other hand, this molding is also required to be decorative, and one example of such decoration is displaying the vehicle name, mark, etc. on its surface.

(Problem to be solved by the invention) However, conventionally, such indications have been made by printing or pasting cut-out characters of colored film on the surface of extrusion molded products, and the indications have been In addition to chipping, there was a tendency for display to be missing.

Therefore, this invention aims to eliminate the above-mentioned drawbacks and provide a new decorative molding having a more three-dimensional display.

(Means for solving the problem) By the way, the present inventor applied a pattern to both sides of a transparent plastic board by halftone printing, which is conventionally used for printing photographs of newspapers, etc., and when viewed from one side, , that a mixture of colors occurs, that is, a composition of colors printed on both sides occurs, and a completely new color appears, and that the pattern can be seen extremely three-dimensionally by changing the viewpoint. They found this and came up with this idea.

To explain this proposal based on the drawings, Figure 1 is a cross-sectional view of the decorative molding according to the invention, and Figure 2 is an enlarged plan view (printed with halftone dots) of the transparent plastic plate that constitutes the decorative molding. , FIG. 3 is a partial perspective view of the decorative molding.

The decorative molding 10 is made up of a transparent plastic plate 20 having a pattern 21 printed on its upper and lower surfaces by halftone dot printing, and a cured layer 30 of liquid transparent plastic cast on one side (upper surface) of the transparent plastic plate 20.

The halftone printed pattern 21 is made up of a network of dots as shown in the enlarged plan view of FIG. 2, and its shading is determined by the density and size of the dots. It is preferably comprised of 40 to 80 dots per inch and 0.10 to 0.2 mm in diameter. The patterns 21 printed on both sides of the transparent plastic plate 20 do not necessarily have to be symmetrical, and a slight deviation may produce a greater three-dimensional effect due to light refraction, reflection, etc. Also, as a matter of course, the printing colors on the upper and lower surfaces are selectively printed in order to obtain the desired color vision. Then, on one side (lower side), the pattern 21 is printed and then the entire surface is printed or painted opaquely with opaque ink or paint to form a back layer 40. Therefore, from the opposite side, the 40 colors of the back layer can be seen as the ground color. The transparent plastic plate 20 may be any transparent plastic plate made of methacrylic resin, polycarbonate resin, polystyrene resin, polyvinyl chloride resin, etc., and its thickness is appropriately selected depending on the desired three-dimensional effect.

Transparent plastic plate 20 configured in this way
On the other side, that is, on the upper side on which only the halftone dot pattern 21 is printed, a transparent plastic layer 30 made of liquid transparent plastic that is cast and hardened is integrally formed. This transparent plastic layer 30 is made of transparent polyurethane resin, transparent methacrylic resin, etc., and is formed into rounded corners that bulge at the periphery of the transparent plastic plate 20 due to the viscosity and surface tension of the resin during casting. It is. Therefore, the pattern 21 printed on the upper surface of the transparent plastic plate 20 is covered and protected by the transparent plastic layer 30 and can be seen through the transparent plastic layer 30.

This decorative molding 10 has an adhesive such as double-sided adhesive tape applied to its lower surface, that is, the outer surface of the back layer 40 of opaque ink or paint, and is pasted onto a desired side of the vehicle body or an object to be decorated or otherwise It may be applied to a substrate, for example a buffer strip such as an extrusion, and fixed together with the substrate to the object to be decorated.

As described above, the decorative molding of this project is made by printing a pattern on both sides of a transparent plastic plate by halftone dot printing, and then printing on one side with opaque ink, etc., and on the other side with rounded corners using liquid transparent plastic. Since it is formed by forming a transparent coating layer, as shown in Figure 1, the pattern printed on the transparent plastic board is caused by the light reflected from the top surface and the light incident and reflected from between the points that make up the pattern on the top surface. When combined with light, a new color can be seen that differs from the colors of the upper and lower patterns. Furthermore, by shifting the viewpoint, the colors that are synthesized change, and the pattern on both the upper and lower surfaces can be seen in an extremely three-dimensional manner. Furthermore, since the top surface of the transparent plastic plate is integrally coated with a lens-shaped transparent plastic layer with rounded corners, the pattern printed on the transparent plastic plate can be seen more three-dimensionally, and the pattern is protected, eliminating the possibility of missing parts. Most of these concerns can also be eliminated. Therefore, it is possible to provide an extremely useful decorative molding to be attached to the side surface of a vehicle body, etc.
