Cosmetic sheet and cosmetic plate

A decorative plate comprising a decorative sheet on a base, wherein the base has a thermal conductivity of less than 0.1 W/(m·K) on a side to which the decorative sheet is bonded, wherein:

• (1) the decorative sheet comprises non-halogen-based thermoplastic resin-containing layers,
• (2) at least one of the non-halogen-based thermoplastic resin-containing layers is a layer containing a non-halogen-based flame retardant,
• (3) the total thickness (μm) of the non-halogen-based thermoplastic resin-containing layers is referred to as x, the percentage (mass %) of the total mass of the non-halogen-based flame retardant in the non-halogen-based thermoplastic resin-containing layers in 100 mass % of the total mass of the non-halogen-based thermoplastic resin-containing layers is referred to as y, x and y satisfy the following equation (I):

• (4) the content of the non-halogen-based flame retardant in the layer containing a non-halogen-based flame retardant is 11 mass % or more, and
• (5) the decorative sheet comprises at least one member selected from the group consisting of a transparent resin layer, a base sheet, and a synthetic resin backer layer as one of the non-halogen-based thermoplastic resin-containing layers, and the transparent resin layer and/or the base sheet comprises the non-halogen-based flame retardant,
• a resin forming the base sheet consists essentially of at least one member selected from the group consisting of polyolefin, polyester, polyacryl, polyamide, polyurethane, and polystyrene, and
• a resin forming the synthetic resin backer layer consists essentially of at least one member selected from the group consisting of polypropylene, ethylene-vinyl alcohol copolymer, polymethylene, polymethylpentene, polyethylene terephthalate, highly heat-resistant polyalkylene terephthalates, polybutylene terephthalate, polyethylene naphthalate, polyethylene naphthalate-isophthalate copolymer, polycarbonate, polyarylate, polyimide, polystyrene, polyamide, and ABS.
