る。2. Description of the Related Art Conventionally, resin molded articles have been produced by various molding methods such as injection molding, compression molding, and blow molding, and used for various purposes. As the molding resin, various resins such as polypropylene resin and ABS have been used depending on the use of the molded product and the molding method. In addition, a large number of molded articles, which are not simply molded articles but are provided with a design or information by decorating the surface with patterns or characters, are also used. For example, a method of laminating a sheet to which characters or patterns are given in advance on the surface of a molded product and integrating them is used. In this case, the sheet is laminated on the molded article after molding, or the sheet is inserted into the molding die, and the sheet is laminated on the surface of the molding resin at the same time as the molding of the molded article and integrated with the molding resin. There is a method to make a product.

外観を損なうといった問題がある。In the case where the sheet is integrated with the molding resin at the same time as molding, a heat-fusible resin film is laminated on the back side of the sheet for simultaneous painting and heat-sealing. As a heat-fusible resin layer formed by applying a mold adhesive or the like, the adhesive force of the resin layer is activated by the heat of the resin to be molded, and the sheet and the molding resin are thermally bonded.
On the other hand, as the molding resin, an inexpensive polyolefin resin such as a polypropylene resin is preferable from the viewpoint of cost and the like,
Since the adhesiveness is inferior to other resins, it was difficult to laminate the sheet with a strong adhesive strength at the same time as the other resins. In particular, in the blow molding method, the temperature of the molding resin that comes into contact with the sheet is often lower than that of injection molding or the like. May not be able to increase the adhesion strength. As a method for solving such a problem, if a sheet in which a nonwoven fabric or the like is adhered to the back surface of the sheet is used, the molding resin penetrates between the fibers, so that the adhesiveness can be improved. However, in addition to the process of bonding the nonwoven fabric, if the nonwoven fabric is thick, unevenness based on the fibers of the nonwoven fabric is generated on the sheet surface after lamination, and the surface condition is deteriorated,
There is a problem that the appearance is impaired.

よって成され得る。In order to solve the above-mentioned problems, a sheet for simultaneous painting according to the present invention is characterized in that after the sheet is inserted into the mold, the resin is molded by the mold and the molded resin and the sheet are simultaneously formed. In the sheet used in the simultaneous molding and painting method to be integrated, a large number of fine projections are formed on the back side surface of the sheet in contact with the molding resin. As a result, when the molding resin comes into contact with the sheet, the heat from the molding resin is reliably transmitted to the projections, and even when the sheet surface is in contact with the molding die, the projections are far apart. The heat of the projections is hard to be cooled by the mold. Therefore, a sufficiently heated convex portion can provide a higher thermal fusion force than other portions. In addition, the convex portion can enter the inside of the molding resin, and is sufficiently heated by heat to be melted or softened and deformed, thereby obtaining an adhesive force by a wedge effect or an anchoring effect. As a result, strong adhesion of the sheet can be achieved by the projections.

A sheet for simultaneous painting at the same time can be obtained easily. Also, in such a sheet for simultaneous painting, at least the back side of the sheet is made of a resin layer containing a polyolefin resin, since the polyolefin resin has a weak heat-sealing force, so that the adhesive force is improved by the wedge effect of the convex portion. Is particularly effective.

At the same time, the molding resin and the sheet are integrated. Further, in the simultaneous molding and painting method of the present invention,
A blow molding method is particularly effective as a molding method for integrating a molding resin and a sheet. In blow molding, the temperature of the molding resin that comes into contact with the sheet is often lower than in injection molding or the like. Even if the back surface of the sheet is not sufficiently melted, sufficient heat is applied to the protrusions, and the heat generated by the protrusions themselves. In addition to fusing power,
In combination with the wedge effect in which the projections sunk into the molding resin, the adhesion strength is increased by the projections. In addition, such a simultaneous molding and painting method is characterized in that, when at least one of the resin layer constituting at least the back side surface of the sheet or the molding resin contains a polyolefin resin, the thermal fusion force of the polyolefin resin Therefore, the improvement of the adhesion by the wedge effect of the projection is particularly effective.

Is formed. In the case of FIG. 1, the resin layer 1 is a layer made of a resin sheet or the like and serves as a base sheet, and the protrusions 2 are also made of the same material as the resin layer 1, that is, integrated with the resin layer 1.
Further, the convex portion 2 in FIG. 1 is a convex portion formed around a through hole 3 formed so as to penetrate all the layers of the sheet S for simultaneous painting. When the through hole 3 is a round hole, the planar shape of the convex portion 2 is a circular shape formed in an annular shape around the entire periphery of the through hole 3. On the other surface of the resin layer 1, characters, patterns, and the like are formed as a decoration layer 4 by printing or the like, and further, over the entire surface of the resin layer 1 including the decoration layer 4, the protection of the decoration layer, the provision of a design feeling, and the like. Therefore, the transparent resin layer 5 is formed.

力向上が得られることになる。FIG. 2 shows the state of the projections when the sheet S for simultaneous simultaneous painting of the present invention as exemplified in FIG. 1 is laminated on the surface of a molded article (molded resin) simultaneously with molding. It is sectional drawing which shows notionally. As shown in FIG. 2, if the sheet for simultaneous simultaneous painting of the present invention is used, the convex portion 2 as exemplified in FIG. 1 enters the inside of the molding resin 6 like a wedge,
The convex portion 2a can be deformed by being melted or softened by heating. As a result, the sheet S for simultaneous painting and the molding resin 6 can be firmly adhered by the adhesive force by the wedge effect in addition to the heat fusion force by the sufficiently heated projection itself. Therefore, even when the combination of the resin forming the back side surface of the sheet for simultaneous painting and the molding resin 6 has poor adhesion, the protrusion 2 can be adhered by the wedge effect. Even if the projection does not sufficiently enter the inside of the molding resin, the projection is located farthest from the molding die and is easily heated by the molding resin. The adhesion between the sheet for simultaneous painting and the molding resin can be improved.

In the meantime, the sheet 10 for simultaneous forming and painting shown in FIG. 3 has a decorative layer 12 formed on the front and side surfaces of a resin layer 11 serving as a base sheet, and a transparent resin layer 1 on the entire surface of the resin layer 11 including the decorative layer 12.

In this case, it is easy to form, and it is not necessary to make the adhesion between the convex portion and the resin layer necessary, and the convex portion is preferably a material firmly adhered to the resin layer. However, in the present invention, the protrusions are not necessarily made of the same material as the resin layer.

ラは８０℃程度に加熱すると良い結果が得られる。The number, shape, forming method, and the like of the convex portions are not particularly limited as long as the above-described effects can be obtained. For example, if a through-hole 3 that penetrates all layers of the sheet for simultaneous forming and painting is formed, and a convex portion is formed in an annular shape around the through-hole at that time, burr or return generated with the perforation can be easily performed. A convex portion can be formed, which is preferable. In order to form such a through-hole 3, in FIG. 1, the resin layer 1 (base sheet)
After the decoration layer 4 and the transparent resin layer 5 are all provided on the sheet, for example, a needle may be penetrated from the sheet surface side. Specifically, if a roller having a large number of needles radially provided on a roller circumferential surface of metal or the like is formed as a perforated roller, and the sheet is passed between the perforated roller and a flexible rubber roller, the sheet is on the back side. Can be formed around the through hole. The needle may be a thinner needle or the like, and the sheet may be pressed against the rubber roller surface with the needle. At this time, the perforating roller, the rubber roller, and the like may be appropriately heated so that the resin layer 1 (base sheet) is plastically deformed and a convex portion is reliably formed around the through hole. The heating temperature is appropriately selected depending on the resin material of the resin layer. For example, in the case of a polypropylene resin, good results can be obtained by heating each roller to about 80 ° C.

分に得られない。The through hole may not be particularly circular in cross section. The size of the through-hole is preferably 0.05 to 0.5 mm in the case of a circular cross section. If the thickness is less than 0.05 mm, a sufficient adhesion improving effect cannot be obtained.
If it exceeds mm, the holes are conspicuous and impair the appearance of the molded article. However, in the present invention, the through hole 3 is not essential, and the resin layer 1
The structure may be such that only the protrusions protrude from the back surface of the device. Such a convex portion can be obtained by an embossing method using a known hot press or the like. The height of the projection is 0.05 m.
m or more is preferable. The higher the height of the projection, the greater the wedge effect. However, if the height is too high, the wedge effect is reduced due to melting and cutting in the middle. Therefore, the height of the protrusion is usually 0.5
mm. In addition, the number of convex portions is, for example, 4 / cm.
It is better to provide two or more. If the number is small, the effect of improving adhesion cannot be sufficiently obtained.

Other structures are not particularly limited as long as a large number of fine projections are formed, and may be various conventionally known structures. Although one example is shown in FIG. 1, for example, a sheet in which only the convex portion 2 is formed on the back surface of the resin layer 1 made of the base sheet may be used. This is a case where a coloring pigment or the like is added to the resin layer 1 and the resin layer itself serves as a decoration layer to decorate the surface of the molded product. However, usually, as shown in FIG. 1, a decorative layer 4 for providing a pattern, a character, or the like is appropriately formed. The base sheet may be a single layer, a multilayer, or the like. In some cases, a resin layer is provided as a layer different from the base sheet. For example, the resin layer is a case of an adhesive layer formed on a base sheet. The decorative layer 4 is formed on the front side, the back side, between the sheets, and the like of the resin layer (base sheet). When the decorative layer 4 is on the front side of the base sheet, the transparent resin layer 5 and the like are appropriately formed to protect the decorative layer 4.

In the case where the resin layer is a heat-fusible resin, in addition to the close contact by the convex portions, the close contact of the resin layer itself and the molding resin by heat fusion can be obtained. For example, in the layer configuration of FIG. 1, when the resin layer is a polypropylene resin or the like, the resin layer is also a base sheet, and may also be a heat sealing layer depending on the temperature of the molding resin. The resin of the resin layer is not particularly limited. A resin may be used as appropriate depending on the molding resin for laminating the sheet, the application, and the like. For example, thermoplastic resins such as polyolefin resins such as polyethylene and polypropylene, acrylic resins, vinyl chloride resins, ABS (acrylonitrile-butadiene-styrene copolymer) resins, styrene resins, AS (acrylonitrile-styrene copolymer) resins, and polycarbonate resins Resin. These can also be used as a base sheet for forming a decorative layer or the like. Specifically, when the molding resin is a polyolefin resin such as polyethylene or polypropylene, it is preferable to use the same type of polyolefin resin as the resin of the resin layer. In particular, in the present invention, polyolefin resins such as polyethylene, polypropylene and the like have good adhesion, so polyolefin resins are preferred. In addition, it is particularly effective in the case of a blow molding method in which the heat of the molding resin is lower than that of injection molding or the like.
