Problems solved by technology

However, in order to impart sufficient absorption and permeability to the patterned layer, this decorative material needs to add a large amount of filler pigment or porous material. At this time, the patterned layer becomes porous and weak, so the durability and stain resistance of the recesses are reduced
On the other hand, when the porosity of the pattern layer is suppressed in order to improve the durability and stain resistance of the recesses, there is a problem that recesses with sufficient depth and clarity cannot be formed.
In addition, because this kind of decorative material has physical unevenness, it feels bad, and there is still room for further improvement on this point.

Embodiment 1

[0198] As the substrate 2, use the American standard weight per unit area of ​​30g / m 2 On one side of the inter-paper reinforced paper for building materials, acrylic resin and nitrocellulose are used as binders, titanium dioxide, iron oxide red, and chrome yellow are used as colorants, and the coating amount is 5g by gravure printing. / m 2 The (overall) layer forms the colored layer 6 . On top of it, use nitrocellulose as a binder and ink containing a colorant mainly composed of iron oxide red to form a pattern layer 7 of wood grain patterns by gravure printing.

[0199] Next, use the coating composition with a coating amount of 7g / m 2 Carry out gravure printing on the whole surface to form the anti-penetration layer 8 (primer layer). The coating composition used will be a polyester urethane resin with a number average molecular weight of 20,000 and a glass transition temperature (Tg) of -59.8 ° C. A polyisocyanate composed of methylene phenyl diisocyanate is used as a bin...

Embodiment 2

[0204] In the low-gloss pattern ink described in Example 1, a mixture of 90% by mass of polyester urethane resin and 10% by mass of unsaturated polyester resin was used as a binder resin, and as a colorant, A decorative material was obtained in the same manner as in Example 1, except that carbon black and red iron oxide were added to color a dark brown colorant.

[0205] The decorative material was evaluated for gloss, water resistance, peelability over time, stain resistance, and marring performance. Table 1 shows the results.

[0206] For the decorative material obtained in Example 1 and Example 2, observe its cross-section with a microscope magnification, and observe: the low-gloss state of the low-gloss pattern ink layer in the surface protection layer and its vicinity become scattered light, and in addition , the other surface layers do not scatter light and become highly transparent. In addition, when the decorative material was visually observed from the surface prote...

Embodiment 3

[0208] Except having made the silica particle of 5 micrometers of average particle diameters into 8 mass parts in an electron beam curable resin composition, it carried out similarly to Example 1, and obtained the decoration material.

[0209] The decorative material was evaluated for gloss, water resistance, peelability over time, stain resistance, and marring performance. Table 1 shows the results.

Abstract

A decorating material which comprises a substrate, a low glossy designated layer provided on at least a part thereof, and a surface-protecting layer which is present on and contacts with the designated layer and covers over the whole surface including the region having the designated layer and that having no designated layer, wherein said surface-protecting layer is formed by crosslinking and curing an ionization-curable resin composition, and wherein, in said surface-protecting layer, a low lustrous region being visually recognized as a concave portion is formed in the portion directly on said low glossy designated layer and in the vicinity of the portion. The decorating material has a design being formed on the surface thereof and exhibiting a difference in gloss according to the design, which difference is visually recognized as a concave portion, to provide a concave-convex feeling to the surface.

Description

technical field [0001] The present invention relates to a decorative material having a pattern formed on the surface, having visual unevenness by having a gloss difference corresponding to the pattern, and having excellent durability on the surface including the pattern. Background technique [0002] As surface decorative boards of furniture and kitchen products such as kitchen cabinets, it is generally used: using adhesives to attach wood-like materials, inorganic materials, synthetic resin materials, steel plates and other metal materials, such as printed wood grain A decorative board with a structure made of decorative sheets such as tonal patterns. [0003] The decorative sheet used for this surface decorative board requires moderate flexibility, machinability, fracture resistance and other processing suitability for secondary processing such as lamination processing, coiling processing, and V-cutting processing, as well as durability in use. Various properties such as ...
