[0003] As such matte sheet, for example port
It is disclosed in Japanese Laid-Open Patent Publication No. 4-82736, which is obtained by laminating and embossing a top sheet obtained by mixing colored vinyl chloride (PVC) with resin-made colored beads into a sheet and a base sheet which is a colored sheet made of PVC. As described above, there is a topcoat layer formed by coating the base sheet with a paint to which colored beads have been added, and the resulting matte sheet is a so-called frosting where the colored beads frosted the ground. The design is given.

[0004]

However, the former matte sheet having the above-mentioned marbling design has a matte effect, but since the gloss of the sheet surface is almost determined by embossing, the reflectance ( Measurement by a gloss meter The incident angle: 60 °) is limited to about 2.5% and cannot be made lower than that, and the matting effect cannot be sufficiently obtained.

In the latter matte sheet, the top coat layer needs to be about 20 to 40 μm in a dry state.
For this purpose, the paint must be coated on the base sheet in a wet state by about 80 to 120 μm, and if the coating amount of the paint is large as described above, the solvent in the paint penetrates into the sheet, and the sheet remains in the sheet even after drying. There is a problem that the odor remains forever and the odor does not disappear forever and gives an unpleasant feeling.

The present invention has been made in view of the above points, and an object of the present invention is to adopt a type in which a top sheet mixed with colored beads is laminated on a base sheet as in the former case, and By specifying the matrix, it is intended to obtain a matte sheet having a marbled design with excellent matte effect and physical properties.

[0007]

In order to achieve the above object, in a first solution of the present invention, a top sheet having a squeeze pattern on its surface is laminated on a colored base sheet. Further, the above-mentioned top sheet is constituted by mixing colored beads made of a resin of a different color into a transparent matrix using a matte resin and taking out the sheet.

In the second solution of the present invention, a top sheet having a squeeze pattern on its surface is laminated on a colored base sheet. Further, the above-mentioned top sheet is constituted by mixing colored beads made of resin of different color and crosslinked acrylic fine particles into a transparent matrix using a matte resin and taking out the sheet.

According to the seventh solution of the present invention, the first , second,
In the solution means of 3 or 4, the average particle diameter of the colored beads is set to 5 to 50 μm.

[0014]

With the above-mentioned constitution, in the means for solving the first, fifth and seventh aspects of the present invention, since the matting resin which is the matrix of the top sheet can provide the matting effect, the embossing is not sufficient. The matte effect is complemented by the matte effect of the matte resin, and an excellent matte effect is obtained. Further, since the top sheet is laminated on the colored base sheet, no solvent remains in the sheet as in the case of forming the top coat layer by coating, and there is no discomfort due to residual odor.

In the second to fifth solutions of the present invention, the surface of the top sheet is roughened by the crosslinked acrylic fine particles mixed in the matte resin which is the matrix of the top sheet, and the gloss disappears due to irregular reflection of light. Further excellent matting effect can be obtained. In addition, the crosslinked acrylic fine particles are not plasticized even when processed at a high temperature, so that the surface roughness of the top sheet remains and the matting effect is secured.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a matte sheet A according to an embodiment of the present invention, wherein 1 is a colored base sheet and 2 is a top sheet laminated on the colored base sheet 1. Both the colored base sheet 1 and the top sheet 2 are sheets that have been calendered. By laminating the topsheet 2 thus sheeted on the colored base sheet 1, the discomfort caused by the residual odor of the solvent when the topcoat layer is formed by coating is eliminated.

On the other hand, the colored base sheet 1 is, for example,
Polyvinyl chloride (PVC), polyethylene (PE), Po
Synthetic resin such as polypropylene (PP) and polyester (PET) is used as a matrix and is molded into a sheet,
Opaque due to added pigment.

As a feature of the present invention, the top sheet 2 is used.
A transparent matrix to which no pigment is added is used as, for example, partially cross-linked polyvinyl chloride (hereinafter, partially cross- linked polyvinyl chloride).
Matte resin such as PVC) is used. The ratio of the matting resin to the total composition is preferably set to 50 to 100 parts by weight in order to effectively obtain the matting effect. This matte resin is designed to supplement the matte effect by embossing, which will be described later.

The matrix of the top sheet 2 is mixed with resin-colored colored beads 3 of different colors. The colored beads 3 are obtained by emulsion-polymerizing a monomer such as acrylic resin or polyurethane into particles having an average particle diameter of 5 to 50 μm, and are colored by dispersing a coloring material such as a pigment in the monomer. A marbling effect is obtained by the colored beads 3 of different colors.

Further, the surface of the top sheet 2 is embossed to form a suede-like squeezing pattern so as to obtain a matte effect.

In addition to the colored beads 3, crosslinked acrylic fine particles may be mixed in the matrix of the top sheet 2. By mixing the crosslinked acrylic fine particles, the surface of the top sheet 2 is roughened, and the diffused reflection of light causes the gloss to be lost to obtain a further excellent matting effect. Further, since the crosslinked acrylic fine particles do not plasticize at the time of high temperature processing, the surface roughness of the top sheet 2 is left to ensure the matting effect.

Further, as the matrix of the above-mentioned top sheet 2, methylmethacrylate-butadiene-styrene is used.
Copolymer (hereinafter abbreviated as MBS resin) , methyl
Tacrylate-acrylonitrile-styrene copolymer
(Hereinafter abbreviated as MAS resin) and ethylene-acetic acid
At least one resin selected from vinyl copolymers (hereinafter abbreviated as EVA resin) may be used in combination with the matting resin. Due to the resin characteristics due to the mixing of these resins,
It is designed to give an excellent matting effect and improve physical properties such as cold shock resistance.

Furthermore, as the matrix of the top sheet 2, vinyl chloride- urea is used instead of the matting resin.
A tan copolymer (hereinafter abbreviated as PVC-PU resin) can also be used. Due to the characteristics of this PVC-PU resin, a more excellent matting effect is imparted, and physical properties such as cold shock resistance and tensile elongation are improved.

Next, Table 1 shows an experimental example.

The matte sheet A used in the experiment was laminated and embossed with the top sheet 2 and the colored base sheet 1 each having a thickness of 0.1 mm according to the formulation shown in Table 1.
A suede-like squeezing pattern was formed on the surface of the top sheet 2.

[0029]

[Table 1]

As a result, in Experimental Example 3, the reflectance of the surface of the matte sheet A (measured by a gloss meter, incident angle: 60
°) was as low as 1.5% and in Experimental Example 2 as low as 2.0%,
Experimental Example 4 had a high value of 2.5%, and Experimental Example 1 had a high value of 3.0%. This means that in Experimental Examples 2 and 3, the combination of the colored beads 3 and the matting resin compensated for the matting effect, which was lacking only by embossing, with the matting resin, resulting in excellent matting effect and marbling effect. However, in Experimental Example 1, the matting resin was not mixed and the matting effect was obtained only by embossing, and the matting effect could not be sufficiently exhibited. On the other hand, in Experimental Example 4, Since the colored beads 3 were not blended, neither the matting effect nor the marbling effect was sufficiently exhibited.

In Experimental Examples 8 and 9, the reflectance of the surface of the matte sheet A was as high as 1.0%, and the matte effect was sufficiently exhibited. This is because the surface of the top sheet 2 is roughened by the crosslinked acrylic fine particles added to the matrix of the top sheet 2 and the luster disappears due to irregular reflection of light. Further, in the matte sheet A to which the crosslinked acrylic fine particles are added, the crosslinked acrylic fine particles are not plasticized even when processed at a high temperature, so that the surface roughness of the top sheet 2 can be left and a matte effect can be secured. it can.

Also in Experimental Examples 5 to 7 and 9, the matting effect and the marbling effect were excellent. This is the MBS resin, MAS used in the matrix of the top sheet 2.
This is due to the characteristics of the resin and EVA resin, and further physical properties such as cold shock resistance can be improved.

Also in Experimental Example 10, the matting effect and the marbling effect were excellent. This is due to the characteristics of the PVC-PU resin used in the matrix of the top sheet 2, and it is possible to improve physical properties such as cold impact resistance and tensile elongation, which are not listed in Table 1. it can.

Further, in each experimental example, since the top sheet 2 is not formed by coating, the solvent in the paint does not remain in the sheet, and the discomfort due to the residual odor can be eliminated.

[0035]

As described above, the first, fifth, and seventh aspects are provided.
According to the present invention according to the above, because the matte resin is a matrix of the top sheet to obtain a matte effect, the matte effect, which was a little lacking only by embossing, is compensated by the matte resin, and an excellent matte effect is obtained. Obtainable.
Further, since the top sheet is laminated on the colored base sheet, discomfort caused by the residual solvent as in the case of coating can be eliminated.

According to the present invention according to claims 2, 5 and 7,
Since the crosslinked acrylic fine particles are mixed in the matte resin which is the matrix of the topsheet, the surface of the topsheet can be roughened by the crosslinked acrylic fine particles to obtain a further excellent matting effect. Further, since the crosslinked acrylic fine particles are not plasticized even when processed at high temperature, the surface roughness of the top sheet can be left and the matting effect can be secured.

According to the present invention according to claims 3, 5 and 7,
MBS as a matte resin that is the matrix of the top sheet
At least one of resin, MAS resin and EVA resin
Since one or more resins are mixed, excellent matting effect can be provided by the characteristics of these resins, and physical properties such as cold impact resistance can be improved.

According to the present invention of claim 4 or 7, since PVC-PU resin , which is the matrix of the top sheet , is mixed, a more excellent matting effect can be imparted by the characteristics of this resin, and Physical properties such as cold shock resistance and tensile elongation can be improved.
