Further, in order to accelerate the curing reaction, if necessary, heating may be performed after coating.

Can be used.

The surface protective layer 4 is formed by curing an ionizing radiation curable resin composition described later. The film thickness of the surface protective layer 4 is usually about 15 to 35 g / m ² . The surface protective layer 4 is made of an ionizing radiation-curable resin 6 containing organic particles 5 having a particle size of 1.2 to 2.0 times the thickness T of the layer 4. That is, the ionizing radiation-curable composition obtained by adding the organic particles 5 to the ionizing radiation-curable resin 6 was applied to the pattern layer 3 side of the one provided with the pattern layer 3 and cured to form the surface protective layer 4. At this time, the ionizing radiation-curable resin 6 containing the organic particles 5 having a thickness of 1.2 to 2.0 times the thickness of the surface protective layer 4 and protruding partially on the surface of the surface protective layer 4 is used. , A surface protection layer 4.

The thickness T of the surface protective layer 4 is arbitrary, but is usually 15 to 35 μm, and is generally about 25 μm.

Examples of the organic particles 5 include plastic beads made of a synthetic polymer compound. Examples of the type include resins such as acrylic, polycarbonate, urethane, melamine, styrene, and fluororesin. Among these, organic particles made of acrylic and urethane resins are preferred because of their good coating suitability and good ink stability. The particle size of the organic particles is preferably from 5 to 100 μm, more preferably from 10 to 50 μm. If the particle size of the organic particles is less than 5 μm, a sufficient effect cannot be obtained and 1
If it exceeds 00 μm, the coating aptitude may be reduced.

The organic particles 5 have a particle size such that the thickness of the surface protective layer 4 is 1.2 to 2.0 times, but the thickness of the surface protective layer 4 is less than 1.2. In this case, there is a disadvantage that surface irregularities are poor. On the other hand, if it exceeds 2.0 times, there is a disadvantage that the surface scratching property is weakened. By incorporating organic particles, there is an effect that smooth surface properties can be obtained as compared with the case of incorporating inorganic particles. The organic particles 5 preferably have transparency,
The higher the transparency, the better.

The content of the organic particles 5 is preferably 5 to 20% by weight. When it is in this range, a decorative sheet having a feeling of unevenness can be obtained. In addition, if it is out of the above range, there is a possibility that surface irregularities become poor.

In the present invention, the ionizing radiation-curable resin 6 constituting the surface protective layer 4 has an average molecular weight between crosslinks of 1
50-1000 ionizing radiation-curable resin, and the ionizing radiation-curable resin 6 constituting the surface protection layer 4 is:
Further, it preferably contains spherical particles 7 having a Knoop hardness of 1300 kg / cm ² or more. With this configuration, the wear resistance is further improved.

The Knoop hardness referred to here is a minute indentation hardness measured using a Knoop indenter, and the load when a diamond-shaped indentation is formed before the test is obtained from the length of the longer diagonal line of the permanent dent. It is a value represented by the quotient divided by the projected area of the dent. This test method is described in ASTM C-849.

Specific examples of the material of the spherical particles 7 include inorganic particles such as α-alumina, silica, chromium oxide, iron oxide, diamond, and graphite. Further, as the α-alumina, there are fused alumina, Bayer alumina and the like,
Examples of the inorganic particles other than those described above include zirconia, titania, and a eutectic mixture of these materials, fused alumina, and Bayer alumina. The method of forming the shape of these inorganic particles into a sphere is as follows: a method in which a pulverized amorphous inorganic compound is put into a high-temperature furnace having a melting point or higher and melted to be spherical by using surface tension; Melted at a high temperature equal to or higher than the melting point, and blown out into a mist to form a sphere.

Particularly preferred spherical particles 7 include spherical α-alumina because they have a very high hardness and a large effect on abrasion resistance, and spherical particles are relatively easily obtained. . As described in JP-A-2-55269, a small amount of a spherical α-alumina is added to a pulverized product such as fused alumina or sintered alumina by adding a mineralizer or crystallization agent such as alumina hydrate. And 1400 °
By performing the heat treatment at a temperature equal to or higher than C for 2 hours or longer, a cutting edge in alumina is reduced and a shape having a spherical shape is obtained at the same time. Such spherical alumina is available from Showa Denko KK as "Spherical alumina AS-10, AS-2".
0, AS-30, AS-40, and AS-50 ".

The spherical particles 7 can be treated on the surface of the particles. For example, treatment with a fatty acid such as stearic acid improves dispersibility. In addition, by treating the surface with a silane coupling agent, the adhesion to the crosslinkable resin used as a binder and the dispersibility of the particles in the coating composition are improved. Examples of the silane coupling agent include an alkoxylan having a radical polymerizable unsaturated bond in a molecule.

When the ionizing radiation-curable resin 6 has an average molecular weight between crosslinks within the above range, scratch resistance, stain resistance,
The effect of being excellent in solvent resistance and water resistance is obtained. When spherical particles 7 having a Knoop hardness of 1300 kg / cm ² or more are contained, there is an effect that abrasion resistance can be imparted. The spherical particles 7 may be organic particles, but inorganic particles are preferred because ink sedimentation stability is good. The spherical particles 7 preferably have transparency, and the higher the transparency, the more preferable.

The spherical particles 7 may have a smooth curved surface such as a true sphere, an ellipsoidal sphere obtained by flattening a sphere, and a shape close to a true sphere or an ellipsoidal sphere. In particular, a spherical shape having no projections or corners on the particle surface and having no so-called cutting edge is preferable. The spherical particles 7 greatly improve the abrasion resistance of the surface resin layer itself as compared with amorphous particles of the same material, do not wear the coating device, and come into contact with the coating film after the coating film is cured. It is characterized in that it does not wear the object and the transparency of the coating film is also increased. In the case where there is no cutting edge, the effect is particularly large.

In the above description, the particle size of the spherical particles 7 is preferably 1/2 to 2/3 times the particle size of the organic particles 5 for the reason that a uniform unevenness can be expressed.
Is preferably 0.5 to 1.0 times the thickness of the film. The content of the spherical particles 7 is preferably 15 to 25% by weight.

A structure having a relatively low crosslink density is formed by using a monomer. When the heat resistance, hardness, solvent resistance, etc. of the cured product are required, increase the amount of the monomer within a range that does not hinder coating suitability, or use a trifunctional or higher functional acrylate monomer. It is preferable to use a structure having a high crosslinking density.
