Definitions

  • the present invention relates to a decorative material to be used for interior and exterior finishing of buildings and architecture, fittings, or surface decorations or the like of furniture. More specifically, the present invention relates to a decorative material which, in the case of a woodgrain pattern for example, expresses uneven irregularities such as vessel parts stereoscopically by differences in surface gloss.
  • a synthetic-resin coated layer which is transparent or semitransparent and which has low gloss is formed on the entire printing surface of the substrate where appropriate patterns including recess patterns are printed. Thereafter, on the surface of the synthetic resin layer except the part which corresponds to the recess patterns, a synthetic-resin coated layer which is transparent or semitransparent and which has high gloss is formed. Needless to say, when the relationship between high and low gloss is reversed, it is possible to obtain a decorative material where the relationship between recesses and salients is reversed.
  • the decorative material which is provided with a surface-protective layer formed of an ionizing radiation-curable resin

This is with the proviso that, since the gloss adjusting layer 6 needs to be provided with transparency, which makes at least the base pattern 5 and picture pattern 4 possible to be seen through the layer, as a printing ink, coating agents, or the like which form the layer, it is necessary to use those which contain no coloring agents such as dyes or pigments at all or only in a small amount to an extent where the required transparency is not impaired.

  • the ionizing radiation-curable resin layer 7 when expressing the expression region 3 as a recess, is designed so as to have a higher gloss than that of the surface of the region 3.
  • the ionizing radiation-curable resin layer 7 is formed by being provided with a gradation so that in the vicinity of the outline of the region 3, when departing from the outline of the region 3 and proceeding to the inside of the part where the ionizing radiation-curable resin layer 7 is formed, the gloss of the ionizing radiation-curable resin layer 7 gradually becomes higher.
  • the ionizing radiation-curable resin layer 7 when expressing the expression region 3 as a salient, is designed so as to have a lower gloss than that of the surface of the region 3. Moreover, the ionizing radiation-curable resin layer 7 is formed by being provided with a gradation so that in the vicinity of the outline of the region 3, when departing from the outline of the region 3 and proceeding to the inside of the part where the ionizing radiation-curable resin layer 7 is formed, the gloss of the ionizing radiation-curable resin layer 7 gradually becomes lower.
  • the outline of the picture pattern 4 corresponding to the expression region 3, which is a recess or a salient, does not necessarily precisely coincide with the outline of the stair-like region 3 and it may be deviated to the inside or outside of the outline of the stair-like region 3 to some extent. It is also possible to appropriately adjust the virtual appearance of uneven irregularities by positively deviating the outlines of both patterns slightly from each other. In addition, it is also possible to confer changes in virtual appearance of uneven irregularities depending on places by changing directions or distances of deviations between the outlines of both patterns inside the stair-like region 3.
  • resins used for the ionizing radiation-curable resin layer 7 are those having a viscosity of 0.1 to 1 Pa ⁇ s. This is because when the viscosity is within this range, favorable adhesive properties among layers are achieved. In addition, when the viscosity is lower than 0.1 Pa ⁇ s, layers will become too flexible and will easily collapse and when the viscosity exceeds 1 Pa ⁇ s, layers will become stiff and adhesive properties with the adjacent layers will be deteriorated.
  • resins specifically, ionizing radiation-curable monomers, which do not increase the viscosity thereof with time during printing, are used. These resins do not increase the viscosity thereof since a curing reaction does not proceed when they are in a coating-liquid state at normal temperature during printing. On the other hand, since a curing reaction proceeds rapidly after resins are irradiated with ionizing radiation and resins are cured completely, there are advantages such as the lack of generation of blocking due to poor drying even when printed matter is retrieved or laminated.

  • monomers such as urethane (meth)acrylate, polyester (meth)acrylate, polyether (meth)acrylate, and polyacryl (meth)acrylate are desirable since their surface easily becomes smooth after coating due to their low viscosity and anchor effects to the sealer layer 8, base pattern 5, or the like also improve.
  • Silicone oil is added to the ionizing radiation-curable resin layer 7. This is added as an antipollution agent for preventing surface contaminants of the ionizing radiation-curable resin layer 7 from becoming attached or for allowing the attached contaminants to be easily wiped away with various detergents or solvents. Silicone oil is incorporated in the matrix resin constituted from ionizing radiation-curable monomers.
  • silicone oil unmodified silicone oil, amino-modified silicone oil, epoxy-modified silicone oil, carboxy-modified silicone oil, mercapto-modified silicone oil, carbinol-modified silicone oil, methacryl-modified silicone oil, and phenol-modified silicone oil can be used.
  • the amount of silicone oil is preferably 0.01 to 5 weight% when the total weight of ionizing radiation-curable monomers is taken as a standard. This is because when the amount of silicone oil is less than 0.01 weight%, effects of the addition thereof are not achieved and when the amount exceeds 5 weight%, the aqueous resins of the picture pattern 4 or the like are repelled to cause adhesive failures.
  • the gloss of the ionizing radiation-curable resin layer 7 needs to be designed higher than that of the gloss adjusting layer 6.

  • the surface of the expression region 3 When the expression region 3 is expressed as a recess, the surface of the expression region 3 must be in a low-gloss condition. In order to achieve the condition, as shown in the example in Fig. 1, when the base pattern 5 corresponding to the expression region 3 is exposed in the surface in the region 3, there is a need to adjust the pattern in a low-gloss condition by appropriately adding gloss adjusting agents or the like to printing ink or the like, which forms the base pattern 5. On the other hand, when the expression region 3 is expressed as a salient, there is a need to use printing ink, which makes the surface gloss after printing high, as the printing ink to form the picture pattern 4 corresponding to the region 3.

  • the ionizing radiation-curable resin layer 7 as the high gloss layer and by providing the gloss adjusting layer 6 with low gloss between the layer 7 and the picture pattern 4, it is possible to make the expression of uneven irregular shapes due to gloss more distinctly. Furthermore, due to this gloss adjusting layer 6, the stress generated when the ionizing radiation-curable resin is cured can be relaxed and peeling of the picture pattern 4 or the base pattern 5 or the like can be suppressed.
