    摘要： A toy comprises a toy element comprising a photochromic layer which contains a photochromic compound having a photo memory function (color-memorizing photochromic property), maintains a coloring state by developing a color through the irradiation of ultraviolet rays or sunlight containing ultraviolet rays and changes into decolorizing state through its decolorization by the irradiation of visible light, and a color-changing means which contains at least one of an ultraviolet ray absorbent and a light-shading pigment capable of shading at least ultraviolet rays, changes the photochromic compound of the coloring state into decolorizing state by cutting off ultraviolet rays of sunlight and thereby effecting irradiation of visible light, and maintains the changed state, wherein a function to memorize and maintain coloring and decolorizing states alternately is expressed by arranging the color-changing means under such a condition that it is covering or not covering the photochromic layer.
