  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.

  一种玩具包括一个由光致变色层和一个变色装置组成的玩具元件，光致变色层包含具有光记忆功能（颜色记忆光致变色特性）的光致变色化合物，通过紫外线或含有紫外线的阳光照射显色来保持着色状态，并通过可见光照射使其脱色而变为脱色状态，变色装置包含紫外线吸收剂和至少能遮蔽紫外线的遮光颜料中的至少一种、通过切断太阳光中的紫外线，从而实现可见光的照射，将着色状态的光致变色化合物变为脱色状态，并保持改变后的状态，其中，通过在覆盖或不覆盖光致变色层的条件下布置变色装置，可实现交替记忆和保持着色和脱色状态的功能。
