    摘要： A fluorine-containing curable composition which contains, as essential components, component (A) that is composed of a compound which is a linear polymer having a fluoropolyether in the main chain, while having a trifluoromethyl group at one end of the molecular chain and two or more (meth)acryl groups at the other end, component (B) that is composed of a compound which is a linear polymer having a fluoropolyether in the main chain, while having two or more (meth)acryl groups at each end of the molecular chain, and which has four to ten (meth)acryl groups in each molecule on average, and component (C) that is composed of a non-fluorinated acrylic compound which contains no fluoropolyether structure, while having two or more (meth)acryl groups in each molecule on average; the total blending amount of component (A) and component (B) relative to 100 parts by mass of component (C) is from 0.05 to 50 parts by mass; and the blending amount of component (A) relative to 100 parts by mass of component (B) is 1 to 100 parts by mass. This fluorine-containing curable composition is capable of forming a cured film that exhibits excellent antifouling properties and excellent water repellency, while having a low coefficient of kinetic friction.

    摘要： The present invention provides a decorative sheet comprising a surface-protecting layer, the surface-protecting layer having excellent contamination resistance, alkali resistance, etc., for a long period of time, while limiting the occurrence of breakage and cracks when an impact is applied thereto or during processing; and also provides a decorative plate using the decorative sheet. Specifically, the present invention provides a decorative sheet comprising a laminate, the laminate comprising at least a base material sheet and a first surface-protecting layer in sequence in the thickness direction; (1) the first surface-protecting layer comprising an ionizing radiation-curable resin containing two kinds of aliphatic urethane acrylates, i.e., resin A and resin B, wherein resin A is an aliphatic urethane acrylate with an isocyanurate skeleton, and resin B is an aliphatic urethane acrylate with an alicyclic skeleton without an isocyanurate skeleton, and (2) the first surface-protecting layer having a nanoindentation hardness of 160 MPa or more and 240 MPa or less. The present invention also provides a decorative plate using the decorative sheet.
