Description of the Related Art Decorative materials (including decorative sheets, decorative papers, decorative sheets, etc.) used for the above-mentioned various purposes are resistant to abrasion and scratches caused by contact with human bodies and various articles during long-term use. In order to maintain the beauty of its surface for a long time,
In many cases, a protective layer containing a transparent resin composition as a main component, such as a thermosetting resin or an ionizing radiation curable resin, is provided on the surface. Depending on the application, this protective layer may have a glossy finish such as a mirror surface, but for general applications, it is often desired to have a high-quality matte finish. Therefore, the inorganic powder By adding a matting agent such as, it is often made matte with fine irregularities formed on the surface.

しまうという問題がある。However, in order to make the surface of the protective layer have a good matte state by adding a matting agent, irregularly shaped particles having irregular corners or ridges on the outer shape are used as the matting agent. However, it is necessary to form fine irregularities by projecting a part of the particles from the average surface of the protective layer. Therefore, at the time of contact with an article or the like, when the article or the like collides with the protrusion, the particles fall off the protective layer, or the dropped particles rub the surface of the protective layer to give a streak-like scratch, Alternatively, the pressure of contact with an article or the like causes the particles to sink into the inside of the protective layer, changing the surface shape of the protective layer,
There is a problem that the appearance of the cosmetic material is deteriorated as a change in gloss due to scratches.

てしまうという問題もある。Further, as described above, since the surface of the protective layer is formed with fine irregularities, when contaminants adhering to the surface of the protective material enter into the recesses or the like during use of the cosmetic material, the contaminants are wiped off with a dust cloth or the like. There is also a problem in that it is difficult to wipe off even when attempting to braze it, and therefore, surface contamination accumulates over time during use, which deteriorates the aesthetic appearance of the cosmetic material.

のではない。The above problem is that if spherical particles having no irregular corners or ridges on the outer shape are used as the matting agent, the particles are prevented from falling off from the protective layer due to the particle shape. Intrusion into the layer is unlikely to occur, and since the surface has a gentle shape as a whole, clogging of contaminants in the recesses is unlikely to occur, which can be greatly reduced. However, the irregularities formed by the spherical particles on the surface of the protective layer are completely different from those due to irregularly shaped particles, and since the height difference is gentle and small, the matte feeling obtained by this is also Deficiency and texture (with a unique special look, such as suede or velvet)
Due to the differences in, not always satisfactory for general use.

Has a rough surface with the matting agent protruding from the surface, so that due to the shape and properties of the matting agent particles, scratches, abrasions,
It has no resistance to crushing scratches, etc., and due to the change in surface shape caused by the particles of the matting agent falling off or entering, scratches are likely to remain as a gloss change, and the concave part formed by the gap of the matting agent protruding on the surface If the contaminants become clogged, it will be difficult to remove even if the surface is wiped with a rag.

By providing the layer 3, the irregularities on the surface of the second protective layer 3, which is the surface of the decorative material, become much smoother than the irregularities on the surface of the first protective layer 2, and the surface is scratched, rubbed or rubbed. Even when exposed to a physical attack such as pressing, the hardness of the hard spherical particles 32 resists damage to the second protective layer 3 itself, and since the hard spherical particles 32 are spherical, the particles fall off due to being caught or internal Since it is difficult to get stuck in and the surface shape does not change easily, scars are unlikely to remain as gloss changes.

Moreover, since the uneven shape of the surface is gentle, it is difficult for the concavities to be clogged with contaminants, and the contamination resistance is excellent. In this way, the first protective layer 2 containing the matting agent provides the desired matte feeling to the decorative material, and further, wear resistance and scratch resistance,
It is possible to realize a decorative material having excellent appearance resistance and durability, which is also excellent in stain resistance.

ラス等からなるものを使用することが望ましい。The hard spherical particles 32 may be spherical particles made of a material having a hardness higher than that of the transparent resin composition 31 which is at least the main component of the second protective layer 3. However, the spherical shape here is not necessarily limited to a true spherical shape, and for example, an ellipsoidal shape with a small eccentricity, a polyhedral shape with a large number of surfaces or rounded corners, an acute-angled corner or ridge. It suffices that the outer shape be a shape close to a sphere without having. As the material, there are synthetic resin-based materials such as cross-linked acrylic resin, but inorganic material-based materials are preferable in terms of hardness, and specifically, for example, diamond, silica, alumina, zirconia, hafnia, titania, It is preferable to use one made of zircon, garnet, mullite, chromium oxide, iron oxide, silicon carbide, silicon nitride, glass, or the like.

材質からなるものを使用することが望ましい。However, if the hard spherical particles 32 are opaque or if the refractive index thereof is remarkably different from that of the resin composition 31, the transparency of the second protective layer 3 is lowered and becomes turbid. The matte feeling of the protective layer 2 is not fully utilized, which causes a deterioration in the design of the appearance. Therefore, it is desirable to use, as the hard spherical particles 32, those made of a transparent material having a refractive index difference of 0.1 or less with respect to the transparent resin composition 31 which is the main component of the second protective layer 3.

こと、真球に近くしかも表面が平滑な球状粒子が容易且
つ安価に得られること等を挙げることができる。The refractive index of a general resin composition 31 is usually around 1.5 (for example, about 1.47 to 1.50 in the case of an acrylic urethane resin described later), so that the hard spherical particles 32 are suitable. The range of refractive index is about 1.4 to 1.6. The most preferable hard spherical particles 32 used in the present invention are glass beads. The reason is that the refractive index of glass (silicate) is usually about 1.46 to 1.52, and the general resin composition 31
And the like, that the inside is homogeneous and that the transparency is extremely high, and that spherical particles that are close to a true sphere and have a smooth surface can be easily and inexpensively obtained.

しい。Regarding the particle size of the hard spherical particles 32, the relationship with the thickness of the second protective layer 3 is important, and if the particle size is too small, the effect of improving wear resistance and scratch resistance is poor. ,
On the contrary, if it is too large, the hard spherical particles 32 are likely to fall off the second protective layer 3. Therefore, it is desirable that the average particle diameter of the hard spherical particles 32 is within a range of 0.3 to 1.5 times, and more preferably 0.5 to 1.2 times the thickness of the second protective layer 3. .

On the contrary, if it is too thick, the second protective layer 3 becomes fragile and V-cut processing or lapping is performed. The suitability for secondary processing such as processing is deteriorated, and the matte feeling originally possessed by the underlying first protective layer 2 is reduced due to the thickness of the second protective layer 3 and cannot be sufficiently felt when viewed from the surface. It also causes a deterioration in the design of the appearance. Therefore, generally, the coating amount of the second protective layer 3 is 3 to
It is preferably 6 g / m 2 . And as a thing corresponding to this, the hard spherical particle 32 has an average particle diameter of 2 to
It is desirable to use the one having a thickness of 5 μm.

程度の範囲内とすることが望ましい。If the amount of the hard spherical particles 32 added is too small, the effect of improving the wear resistance and scratch resistance is poor, and if the amount is too large, the transparency of the second protective layer 3 is reduced and the surface irregularities are uneven. Due to the light scattering effect due to the increase of the
The original matte feeling is reduced and the external appearance is reduced, and the second protective layer 3 becomes hard and brittle as a whole, which deteriorates the suitability for secondary processing, wear resistance and scratch resistance. However, it will cause it to worsen. Therefore, the addition amount of the hard spherical particles 32 is preferably within a range of about 10 to 50 parts by weight per 100 parts by weight of the transparent resin composition 31 which is the main component of the second protective layer 3.
