ABSTRACT:
On a support, a porous resin layer which is opaque in a water-unabsorbed state and capable of turning transparent in a water-absorbed state is formed, and also a water-repellent resin layer is so provided as to exist in the porous resin layer at its some area or areas in a co-existent state, to make up a water-metachromatic laminate. A novel toy element can be provided in which latent images standing invisible in a normal condition are rendered visible by means of water as a medium so as to be visually distinguished.
