Patent number: 11072154Abstract: A decorative material that has higher scratch resistance while preventing defects generated during lamination of a gloss-adjusting layer. In a decorative material according to an embodiment of the present invention, a resin component that constitutes a first gloss-adjusting layer is a mixture of a urethane-based thermosetting resin having a polyol and an isocyanate, and an ionizing radiation-curable resin having an acrylic group or a methacrylic group; and the urethane-based thermosetting resin is contained in an amount within a range of 3 parts by mass or more and 100 parts by mass or less relative to 100 parts by mass of the ionizing radiation-curable resin.Type: GrantFiled: May 20, 2019Date of Patent: July 27, 2021Assignee: TOPPAN PRINTING CO., LTD.Inventor: Eiichi Higashikawa

Patent number: 10946610Abstract: In a decorative material, a matting agent is added to, of a first gloss-adjusting layer and a second gloss-adjusting layer, one with lower gloss, where the matting agent has a particle diameter of 1.0 times or more the thickness of the gloss-adjusting layer with lower gloss. Accordingly, sufficient unevenness can be imparted to the surface of the gloss-adjusting layer; thus, glossiness does not increase in oblique observation, and low gloss can be maintained. Therefore, it is possible to provide a decorative material having a feeling of unevenness obtained by the difference in gloss that hardly changes even when observed obliquely.Type: GrantFiled: November 19, 2018Date of Patent: March 16, 2021Assignee: TOPPAN PRINTING CO., LTD.Inventor: Eiichi Higashikawa

Patent number: 10723904Abstract: A decorative material having first and second gloss-adjusting layers, one with lower gloss contains a matting agent having an average particle diameter of 6.0 ?m or more and 15.0 ?m or less. That is, the average particle diameter of the matting agent in the gloss-adjusting layer with lower gloss, i.e., the gloss-adjusting layer whose scratch resistance is likely to be low, is set within an optimal range in which the gloss-adjusting layer has improved or even excellent scratch resistance and designability.Type: GrantFiled: April 16, 2019Date of Patent: July 28, 2020Assignee: TOPPAN PRINTING CO., LTD.Inventor: Eiichi Higashikawa

Patent number: 10640916Abstract: In a decorative material, a matting agent is added to, of a first gloss-adjusting layer and a second gloss-adjusting layer, one with lower gloss, where the matting agent has a particle diameter of less than 1.0 times the thickness of the gloss-adjusting layer with lower gloss. The matting agent can be thereby exposed to the surface while floating in the gloss-adjusting layer. Accordingly, a sufficient matting effect can be obtained in front observation, and unevenness imparted to the surface can be reduced; thus, the effect of scattering obliquely entering light is weakened, and the matting effect can be reduced when observed obliquely. Therefore, a picture pattern expressed by the difference in gloss, i.e., a design, can be made invisible when observed obliquely.Type: GrantFiled: November 19, 2018Date of Patent: May 5, 2020Assignee: TOPPAN PRINTING CO., LTD.Inventor: Eiichi Higashikawa
