Examples of the decorative material base sheet in the decorative material of the present invention having the above structure include polyethylene, polypropylene, saturated polyester, polyvinyl chloride, polycarbonate, and nylon.

PVA, polystyrene, ionomer, polyvinylidene chloride, ethylene-vinyl acetate copolymer, ethylene-vinyl alcohol copolymer.

Thermoplastic resin sheets such as ABS and acrylic resin, composite sheets thereof, etc. are used.

It is sufficient that the surface layer portion of the base sheet for decorative materials is formed of a synthetic resin sheet containing a glittering pigment and having concave portions on the surface.

Therefore, it is of course possible to use a composite base material sheet made by combining the above-mentioned thermoplastic resin sheet with a general base material used in this type of decorative material, such as paper.

In addition, typical examples of base materials used in combination with the thermoplastic resin sheet include, for example, a basis weight of 20
Approximately 200g of paper sheets, raw vinyl wallpaper, valve board, paperboard, gypsum board paper, various types of wood 1 plywood, wood base materials such as particle board, iron, Af2. Metal sheets or plates such as copper, gypsum board, gypsum slag board,
Pulp cement board 1 Asbestos cement board.

A synthetic resin sheet containing a glittering pigment is a synthetic resin sheet containing a glittering pigment,
For example, pearl pigment, gold, silver, copper brass, metal powder such as /1, aluminum hydroxide powder, cut pieces of synthetic resin film with metal vapor deposition layer, mica pieces coated with titanium dioxide, square scale foil, bismuth acid chloride pieces. It is made of a thermoplastic resin sheet filled with glittering pigments that give off pearlescent or interference luster.Although it varies depending on the type of glittering pigments, the resin that makes up the sheet Approximately 20 to 50 parts by weight of a glittering pigment is incorporated per 100 parts by weight.

The concave portions on the surface of the base sheet for decorative materials are formed against the surface of the synthetic resin sheet that will become the base sheet for decorative materials, or against the surface of the thermoplastic resin film or sheet that will become the surface layer of the base sheet for decorative materials. It can be easily obtained by shaping the surface by embossing.

The shape of the concave portion on the surface of the base material sheet for decorative materials is made of a group of fine parallel straight lines or curved lines, especially a group of parallel wavy curves, and the direction of the group of curves is the direction of the wood grain pattern formed by the printed pattern layer. If the surface is formed in a direction perpendicular to the surface, the shine of the wood grain can be expressed very well.

In addition to a group of parallel straight lines, the shape of the concave portion includes, for example, a sine wave, a cycloid curve, an elliptic function, a Bessel function, a group of curves with a constant period or an irregular period in which a plurality of connected circular arcs are arranged in parallel to each other. For example, a shape similar to the fiber shape or hairline shape of the skin of natural wood is used.

The shape of the concave part in a base sheet for decorative material having a concave part on the surface is such that the spatial frequency spectrum obtained by Fourier transforming the horizontal and/or vertical cross-sectional curve of the base sheet for decorative material is a spatial frequency. In the case of an inversely proportional 1/f type or an array shape approximating it, the array has a period that is very similar to the pattern of fluctuations in the human's mental cycle.

This means that the spatial frequency spectrum of the grain of natural wood is also
Since it can be approximated by the /f type, it becomes an excellent decorative material that closely resembles the texture of natural wood, giving people peace of mind.

Note that the concave portion has a 1/f type or an array shape similar to the 1/f type in which the spatial frequency spectrum obtained by Fourier transforming the horizontal and/or vertical cross-sectional curve of the base material sheet for decorative materials is inversely proportional to the spatial frequency. For example, by taking a photo of only the exposed part of natural wood where the wood grain is exposed, by adjusting the lighting, etc., and then subjecting the obtained photo to known photoengraving or photoetching. This can be easily formed by creating an embossing plate in which only the unraveled portion of the natural wood is convex, and performing embossing using this embossing plate.

Furthermore, the concave portions on the surface of the base sheet for decorative materials may be, for example, independent dot-like concave portions.

The recessed portion is normally formed to a maximum depth of about 5 to 200 μm, but in particular, in order to obtain a sufficient design effect by the recessed portion, in Fig. 4 fl) and (2+3),
It is preferable that the concave portion has an opening width of 1 to 100 LL and a depth of approximately 1 to 100 u.

The hiding layer formed in the non-concave portion of the surface of the base sheet for decorative materials is formed, for example, from a paint containing a non-glare pigment with high hiding performance such as titanium dioxide or carbon.

The above-mentioned concealing layer is intended to make the recessed part exhibiting glitter visible from the outside, and is intended to make the recessed portion exhibiting glitter visible from the outside, and is intended to be used to make the recessed portion exhibiting glitter visible from the outside. By forming the above-mentioned concealing layer in the non-concave portions where there is no glare, the concave portions exhibiting glitter can be visually recognized.

Furthermore, the picture-printed pattern layer applied to the decorative material of the actual invention is formed as a normal picture-printed pattern layer suitable for decorative materials, but as shown by the symbol M in FIG. Most preferably, it is formed into a printed pattern layer.

The picture print pattern layer may be directly formed by general printing means, for example, printing means such as gravure, or may be formed as a transfer layer using a transfer sheet.

Moreover, the gloss adjusting resin layer in the decorative material of the invention of water bottle 6 is
For example, mica, silica, alumina, calcium carbonate,
It may be a matte resin layer containing a matting agent such as diatomaceous earth, silica sand, or shirasu balloon, or it may be a polishing resin layer containing no matting agent at all.
Furthermore, a combination of a matte resin layer and the polishing resin layer may be used.

In particular, when forming a gloss-adjusting resin layer by combining a matte resin layer and a glossy resin layer, one is formed solidly, and the other is attached to the transparent to translucent resin layer described above. For example, when a woodgrain pattern pattern layer is formed on the transparent to semitransparent resin layer, the surface of the pattern pattern layer is matte. If the resin layer is formed solidly and the glossy resin layer is formed thereon in synchronization with the autumn wood part of the wood grain pattern, the matte resin layer is synchronized with the spring wood part, and,

The polyethylene resin layer 3 side of the base sheet 4 for decorative materials is heated to 120°C to soften the polyethylene resin layer 3, and then passed through an embossing machine equipped with an embossing roll (roll temperature 20°C) to form polyethylene. Concave portions indicated by the symbol 5°5... were formed on the surface of the resin layer 3.

The embossing roll is made of straight-grained cedar wood (with a minimum grain period of 1 mm in the width direction and a maximum of 20 mm, and a spatial frequency spectrum in the width direction with an approximately 1/f-type distribution). It was obtained by taking a photo of only the part extracted by adjusting the lighting, and using this photo as a basis for photoengraving. are formed in a corresponding manner.

Next, on the surface of the polyethylene resin layer 3, only the non-concave portions of the polyethylene resin layer 3 are coated with an ink in which a brown pigment consisting of titanium dioxide, carbon black, Bengara, and yellow lead is dispersed in chlorinated polyethylene using a gravure printing method. After partially forming a concealing layer indicated by code 6, a transparent resin coating agent containing trocellulose,
SA medium (Showa ink) was applied by gravure coating to form a transparent resin layer 7 with a thickness of 100 μm.

Next, on the surface of the transparent resin layer 7, woodgrain pattern printed pattern layers m, m, etc. are formed using gravure ink and trocellulose ink (SAM: Showa Ink).

[Operations and Effects of the Invention] The decorative material of the present invention comprises a base sheet for a decorative material made of a synthetic resin sheet containing a glittering pigment and having concave portions on the surface, and the base material for a decorative material. In the structure of the concealing layer formed in the non-concave portion of the surface of the sheet and the printed pattern layer, the glittering surface reflection light is collected by the concave mirror effect in the glittering concave portion of the base sheet for decorative materials. The effect of light and the effect of the concealing layer are synergistic, so depending on the angle at which the decorative material is viewed or the angle of incidence of illumination light, the gloss developed from the glitter pigment in the base sheet for the decorative material can be affected. Changes occur and excellent effects are achieved in terms of design.

In addition, in the decorative materials of the inventions of Sui-Tei 2 to 4, the effect of the concave portions having glitter properties using the warmth and cocoon layer in the base material sheet for decorative materials acts from inside the decorative material, resulting in a three-dimensional effect. It expresses a deep shine that has an excellent effect.

Furthermore, since the decorative material of Mizuo 4's invention is formed in such a way that the printed pattern layer is sandwiched between transparent to semitransparent resin layers, it is difficult for a person who visually recognizes the decorative material to see the printed pattern layer. A state in which a shadow is projected onto the base material sheet for decorative material is observed, and moreover, the shadow moves due to parallax.

For this reason, in the decorative material of the invention of Mizui 4, depending on the angle at which the decorative material is viewed, the movement of the glitter and the movement of the shadow of the printed pattern layer are observed, and the movement of the shine on the surface of the wood appears. In particular, by using the decorative materials of the sixth and seventh aspects of the present invention, it is possible to obtain decorative materials that closely resemble decorative materials made of natural wood.

In the decorative material of the sixth invention, the gloss adjustment layer provides
Furthermore, a decorative material that closely resembles a decorative material made of natural wood can be obtained, and the decorative material has excellent fastness.

In the decorative material of the eighth invention, the repeating arrangement of the glittering resin layer is such that the spatial frequency spectrum obtained by Fourier transforming the horizontal and/or vertical cross-sectional curve of the base material sheet for the decorative material is a spatial frequency. Since it is an inversely proportional l/f type or an arrangement similar to it, it has a repeating arrangement that closely resembles the pattern of the fluctuation of the human 6-beat cycle.
Furthermore, since the spatial frequency spectrum of natural wood grain can be approximated by a 1/f type, it becomes an excellent decorative material that closely resembles the texture of natural wood, giving people peace of mind.
