FIELD: physics. ^ SUBSTANCE: protective coating has a layer of polymer material with shape memory, having a surface made of microlenses, where each microlens is associated with one of a plurality of images on the protective coating. The layer of polymer material with shape memory is sensitive to external stimulating effect, for example to temperature, a solvent or moisture, owing to transition from a first state in which the optical property of the microlens has a first value to a second state in which the optical property of the microlens has a second value. The microlenses have refracting surfaces which transmit light to positions in the protective coating, yielding a composite image from images formed on the protective coating when the layer of polymer material with shape memory is in one of a first or second state. ^ EFFECT: invention provides change in optical properties of the article as a result of the external effect. ^ 9 cl, 19 dwg |
