Abstract:
A relatively lightweight wall adhering material includes a non-woven fabric or a water-resistant paper, having a coating weight of from 40 to 150 g/m2 as a substrate and provided thereon a porous layer in an amount of from 5 to 50 g/m2. The porous layer includes a binder resin and a low-refractive-index pigment dispersed in the binder resin and firmly fixed thereto. The water-discoloring wall adhering material has a gross weight of from 50 to 200 g/m2. The water-discoloring wall adhering material has excellent convenience at the time of production and use, promptly forms clear image to perceive, and is difficult to fall down when adhered to a wall.

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.
Abstract:
A writing instrument for a water-metachromatic member has a cylindrical container capable of holding water, formed with an opening at a tip end thereof to communicate the interior of the container with the exterior thereof, a hollow cylindrical holder which directly holds a pen point member, being formed at a tip end with an opening through which the tip end of said pen point member is projected outwardly and at a rear end with a communication hole, and a gap provided between an inner peripheral surface of the cylindrical holder and an outer peripheral surface of the rod-like body to form a gap for generating a capillary force therebetween. When the holder is held to the container, water is supplied through said communication hole to said pen point member. When the holder is detached from the container, the opening of the container is usable for water supply.
Abstract:
In a liquid composition for metachromatic members which is to be applied to a metachromatic member having a support and provided thereon a porous layer formed by fixing therein a low refractive index pigment in a disperse state together with a binder resin, the liquid composition has a liquid medium and dissolved and/or dispersed therein a solid matter having a refractive index of from 1.3 to 1.8. Also disclosed is a metachromatic member set having this liquid composition and a metachromatic member. The liquid composition for metachromatic members satisfies permanent preservability of images, having superior density retention and shape retention of images formed in the metachromatic member and being suitable for uses in which impressions of hands, feet and the like are taken and preserved or in which written images or stamped images are preserved.
