发明名称 Water-discoloring drawing toy set
摘要 <p>To provide: a water-discoloring drawing toy which, when a writing utensil or applicator for water adhesion is applied thereto, produces a multicolor image and which eliminates the monotonous production of monochromatic images in a related-art technique and is rich in unexpectedness and changes; and a water-discoloring drawing toy set including this drawing toy. A water-discoloring drawing toy 1 having such a constitution that a drawing made by applying a writing utensil or applicator for water adhesion produces a multicolor image, the drawing toy comprising: a substrate; many non-discoloring images differing in color tone and adjoining each other disposed on the substrate so that at least two color tones per 100 cm 2 can be visually recognized in the part having the non-discoloring images; and a porous layer for preventing the non-discoloring images from being seen in the ordinary state, the porous layer being disposed over the non-discoloring images and comprising a binder resin and a low-refractive-index pigment fixed therein in a dispersed state, the porous layer having a difference in transparency between a liquid-impregnated state and an unimpregnated state. Also provided is a water-discoloring drawing toy set which comprises the water-discoloring drawing toy 1 and a writing utensil 3 or applicator for water adhesion.</p>
