Abstract
A decorative material includes a substrate, and a decorative sheet laminated on one surface of the substrate. The decorative sheet includes a substrate layer, an aggregate layer, a print pattern layer, and a surface protective layer. The aggregate layer contains a mixture of an acrylic resin and an inorganic filler such that a mixing ratio of the acrylic resin with respect to 100 mass % of the aggregate layer is in a range of 5 mass % or more and 15 mass % or less and a mixing ratio of the inorganic filler with respect to 100 mass % of the aggregate layer is in a range of 85 mass % or more and 95 mass % or less. The aggregate layer has a thickness in a range of 0.2 mm or more and 4.0 mm or less.
Claims13
A decorative sheet comprising:
- a substrate layer;
- an aggregate layer that is laminated on one surface of the substrate layer;
- a print pattern layer that is laminated on a surface of the aggregate layer opposite to a surface of the aggregate layer facing the substrate layer;
- and
- a surface protective layer that is laminated on a surface of the print pattern layer opposite to a surface of the print pattern layer facing the aggregate layer, wherein
- the aggregate layer contains a mixture of an acrylic resin and an inorganic filler such that a mixing ratio of the acrylic resin with respect to 100 mass % of the aggregate layer is in a range of 5 mass % or more and 15 mass % or less and a mixing ratio of the inorganic filler with respect to 100 mass % of the aggregate layer is in a range of 85 mass % or more and 95 mass % or less,
- the aggregate layer has a thickness in a range of 0.2 mm or more and 4.0 mm or less, and
- the inorganic filler contains a filler having a particle size distribution in a range of 50 μm or more and 500 μm or less.
