FIELD: physics, optics.
SUBSTANCE: claimed article comprises retroreflecting film. This film comprises prismatic ply with multiple retroreflecting prismatic elements and opaque reflecting metal coat in prismatic ply. It comprises the separation ply ranking from translucent to semi-translucent arranged under the film and glued thereto. spacer ply is arranged under separation ply and glued thereto. At lest one etched shaped area of at least one image is applied through metal coat to transfer image of at least one light transmitting area. Separation or spacer ply includes one or several of the next contrast elements. Dye, colour shifting additive, fluorescing additive and IR additive visible through at least one etched area to guarantee the contrast relative to not etched area of metal coat. Metal coat is located between separation ply and retroreflecting prismatic element.
EFFECT: better contrast of image in retroreflecting article.
