The invention provides a safety line which comprises a substrate(1) and a grating layer(2). The grating layer is developed on the substrate(1). Under illumination, at least partial area of the safety line is in one color; under the same illumination, after rotating the safety line in the plane thereon for certain angle, the area turns to another color; and the reconstructing light is in linear polarization.
