The laminate has a tensile elongation in accordance with JIS K6251 of 5% or greater, and exhibits no scratch after reciprocating sliding of a #0000 steel wool 1000 times on a surface of the hard coat layer under a load of 1 kg/cm2. The pencil hardness of the hard coat layer may be F or higher. The haze of the laminate may be 2% or less. The total light transmittance of the laminate may be 85% or higher. The hard coat layer may be formed from a cured product of a curable composition that includes a polyfunctional (meth)acrylate and a fluorine-containing vinyl compound. The polyfunctional (meth)acrylate may include a urethane (meth)acrylate and a (meth)acrylate of a polyhydric alcohol-alkylene oxide adduct. The laminate can provide both scratch resistance and stretching characteristics.
