Description

[Detailed description of the invention] <Industrial application field> The present invention relates to architectural interior materials such as wall covering materials and ceiling materials.

O1-Pie's seat cover materials, including vehicle interior materials such as car door panels and headrests.

Sofa cover material, table center for each row.

Coaster - 9 meters each - 2 bags per meter This relates to decorative interior materials made of synthetic resin that are suitable for a wide variety of uses such as footwear, bags, etc. In detail, only the embossed pattern is a different color from the ground color. 1 for decorative interior materials with so-called change colors.
3! It's something you can do.

<Conventional technology> Conventionally, this type of interior material with change color properties has a backing material such as a base fabric that is colored, and a foamed pattern that is colored in a different color from the backing material is placed on the top surface of the backing material. Deep embossed pattern similar to welder emboss/! : The foam layer is completely exposed by IJI, and at the same time, the crushed foam figure is extruded to the back side of the backing material, and the backing material is exposed. Only the execution material is ♀
Then, the technique Shitoi is known. Also recently, the third
As shown in the figure, the base color E! is applied to the top surface of the backing material (14) such as base fabric! After providing t(+3), a transparent foam layer or a transparent colored foam layer (12) is provided on the surface of the transparent foam layer (12). 11
Changeable color interior materials provided with (11) are known. As shown in Fig. 4, unless a deep embossed pattern such as welder embossing is applied to this interior material, the concave portion (15) will take on the color of the base colored layer (13), but this interior material is not suitable for mass production. It was found that it had the following drawbacks.

(a) Lower Il! If the first colored layer is a dark color such as black and the foam layer is a lighter color, a sharp change color will be produced, but if the opposite is the case, no sharp pattern will be produced.

(b) If the foam layer is a transparent foam layer, the coloring of the base coloring layer will result in a product that has a cloudy appearance as a whole.

(c) If the foam layer is a transparent colored foam layer, the layer with the foam diagram crushed is the bottom 1t! Since a thin layer remains on the colored layer, a sharp change color pattern cannot be created.

(d) There is color blurring due to the foaming ratio of the foam layer (13).

(e) Since the foamed layer contains less pigment m, light resistance is poor and it tends to turn brown.

(f) As the product becomes thicker as a whole, you will only get a product that feels lumpy.

(g) Due to reasons (a) to (c), change color products with free color combinations are not allowed.

Problems to be Solved> The present invention provides a novel changeable color interior material L7 that eliminates the drawbacks of the prior art described above.

Means for Solving the Problems> The present invention uses a transparent thermoplastic synthetic resin as the surface layer, and a thermoplastic synthetic resin that is easily melted or easily subjected to high-frequency heating and can be transparent or opaque in any number of colors. As a layer,
The base colored layer is a transparent or opaque thermoplastic synthetic resin layer that is difficult to undergo FJ melting or 8-frequency heating and is colored in a color different from the intermediate color β, and the backing layer is white or the same color as the base colored layer. Each is formed with colored backing material,
This 4F! i was integrally stacked to form a laminate, and a deep embossed pattern such as welder embossing was applied to the surface of this rectangular body so that the concave portions exhibited the color of the underlying colored layer.

<Function> Due to the presence of the surface layer made of transparent thermoplastic synthetic resin, no intermediate colored layer remains in the concave portions of the embossed pattern created by welder embossing, and no intermediate colored layer remains at all in the concave portions of the embossed pattern created by welder embossing. Only one colored layer is exposed, and an extremely sharp color change, that is, a change color, can be obtained anywhere other than the recessed portions. This is especially true when the synthetic resin used for this surface layer is hard to melt or hard to be heated by high frequency. In the case of a three-layer laminate consisting of an intermediate colored layer, a base colored layer, and a backing layer without the front WJ layer, the intermediate colored layer becomes thin and remains in the recesses caused by welder embossing,
There is not much change in color between the intermediate colored portions other than the concave portions, and color change is extremely rare.

<Example> To explain an example of the implementation of the present invention with reference to the drawings, a laminate (A) is composed of a surface layer (1) made of a thermoplastic synthetic resin, an intermediate colored layer (2), a base colored layer (3), and a knitted fabric. [, plain woven fabric, knitted fabric, twill woven fabric.

A backing layer (4) made of two non-woven fabrics and a backing material such as paper are laminated together, and a deep embossed pattern (four parts) (5) is formed on the surface of this laminate (A) by the welder embossing method. Hermitage and its embossed concave N (5)
In this case, no intermediate colored layer remains at all, and as shown in FIG. 2, the somewhat faded surface layer (1') becomes a groove in direct contact with the underlying colored layer (3). A laminate (Δ
), as shown in Figure 2, the intermediate colored layer (2) is completely removed from between the surface layer (1) and the base colored layer to both sides (surroundings) of the fourth part (5), and returns to the surface. The rising part (
6) in the form I′li,v. In this case, the base colored layer (3) is also somewhat raised and extruded on both sides (surroundings) of the recess to form a thick-walled product (7). Also, although it depends on the pressing force during the Welgo embossing, the base coloring 1e(3)' is press-fitted into the back side of the backing material (4), causing so-called bleed-through? 3+i
(3') is formed.

The surface layer (1) is a layer made of a transparent thermoplastic synthetic resin, and although the most suitable synthetic resin is a resin that is difficult to melt or is difficult to be heated by high frequency, it is not limited to such a resin. Any conventional resin well known in the technical field may also be used. However, the intermediate colored layer (2) described later
Is the melting property comparable to that of the intermediate colored layer (2) in relation to ? Although it is possible to use a transparent resin material that has wave heating characteristics, the sharpness of the change color is somewhat inferior to that of the material that is difficult to melt or is difficult to be heated by high frequency waves as described above. However, there is no practical problem, and the presence of the transparent surface layer is important when compared with the case without the surface layer.

In the present invention, the property of being "hard to melt or not easily subjected to high-frequency heating" and the property of being "not easily melted or not easily subjected to high-frequency heating" refers to the surface layer (1) and the inside layer (1). 11 Colored Oka (
2), the intermediate coloring layer (2) and the base coloring F to be described later! J(3) is a relative property that should be determined in relation to 100P)-IR, if
A surface layer made of vinyl chloride resin that is "hard to melt or hard to be heated by high frequency waves" is sufficiently effective for this purpose if the degree of polymerization is about 1800 and the amount of plasticizer is 90 PHR. For a resin with a polymerization degree of 800, a so-called high polymerization degree resin of 1800 was used for the surface layer, but in addition to this, a surface layer that is difficult to melt or is difficult to be heated by high frequency Reduce the dose and get f:) 1q. As a resin that is difficult to be heated by high frequency, there is generally a polymer with a molecule of 4M la that has few polar groups, but thermoplastic polyurethane or thermal 1'iJl polyester can be used as the surface layer in the present invention, and these resins can be used alone or It can be used in combination with vinyl chloride resin.

The intermediate colored layer (2) is a layer colored in any color, and although the coloration is not particularly limited, it is made of a thermoplastic synthetic resin that is difficult to melt due to its relative relationship with the surface layer (1) or can be heated by high frequency. There are 174 layers, and this intermediate colored layer effectively becomes the base color of the decorative interior material. Additions to vinyl chloride resin that are easily melted or easily subjected to high-frequency heating include using a resin with a low degree of polymerization, and using a large amount of plasticizer m.
1η, such as by adding processing additives that promote fluidity. In addition, when a polymer having an essentially polar group-rich structure of 4%, such as a vinyl silicide resin or an ethylene-vinyl acetate copolymer resin, is used in any combination of the surface layer of the thermoplastic polyurethane resin, Demonstrates effective properties.

Base color a(3) is intermediate color 1! l (2) A thermoplastic synthetic resin layer that is difficult to melt or undergo high frequency heating in relation to the surface 1i! ! The same installation 11'+ concept as in (1) is sufficient. Lower I! ! Colored Ff4 (3) has a surface layer (1), an intermediate colored layer (
2) and the four embossed parts (5) when welder embossing the laminate (A) with the center 4'l material (4)
It is a layer exposed to the intermediate color FmC2> ground color,
It exhibits a pattern color due to change color.

The backing layer (4) is knitted cloth, plain woven cloth, and kisho.

Under pressure during welder embossing, the underlying colored layer (3) can be press-fitted or infiltrated (3') with a backing material such as 1 paper of a base fabric such as a twill woven fabric. Structures are suitable. These backing materials (4) originally have a white gray color, so it is preferable to use them in this way, but in special cases, for example, if you want to make the change color more general sharp, use the lower 1 [j1 colored layer] A backing material dyed in β1 color may be used.

Above surface vJ (1), intermediate colored layer (2), lower il! J
Laminated I with colored (3) and backing opening (4) laminated in one piece
In A (△), there is a deep embossed ball or concave part from the surface (
5). By applying this deep embossed pattern, the behavior of each layer described above occurs. This is a phenomenon obtained depending on the properties of each layer. For example, if the transparent surface layer (1) is missing, the removal of the intermediate tube color layer will be incomplete, and the result will not be as shown in Figure 2, and the underlying If the coloring layer is a thermoplastic synthetic resin layer with the same properties as the intermediate coloring opening, the removal of only the intermediate color layer will not occur, and the change color will not be removed from both sides (surroundings) of the recess along with the intermediate coloring m. cannot be obtained. Another 1t back hit! If (4) is missing, then I! 1@ Deformation of the color layer or flow to both sides of the fourth part (5) becomes mossy,
Slightly below the transparent surface layer! This results in a structure in which one colored layer remains, and the removal of the intermediate colored layer (2) also becomes incomplete. This is the first hit! ! Since (4) is a porous material, the underlying colored layer is press-fitted into the porous portion, and as a result of this press-fitting, flow to both sides of the recess and removal are suppressed, and the intermediate colored layer (2) is completely removed.・It becomes something.

Next, aspects of the present invention will be explained in detail using specific examples.
