Abstract

The present invention provides (s) an aqueously color-changing puzzle. The aqueously color-changing puzzle is rich in convenience capable of easily changing the color by wetting and in durability, further is widely applicable. The puzzle piece includes a substrate(2), a water resistant resin layer(3) on the substrate(2), a porous layer(4) on the water resistant resin layer(3). The porous layer(4) is made of a dispersion system of a low refractive-index pigment in a binder resin so that the transparency of the porous layer may differ between in the liquid-absorbing state and in the non-liquid absorbing state.
