Writing instrument for water-metachromatic members |
| abstract |
A writing instrument usable for water-metachromatic members with which writing instrument any desired writing image is formed by means of water on a water-metachromatic member comprising a support and having provided on the surface thereof a porous layer formed of a binder resin to which fine-particle silicic acid stands fixed dispersedly; nsaid writing instrument comprising a main body, a pen point attached to the front end of the main body, and a water absorber held in the interior of the main body; nthe front end of said water absorber being connected to the rear end of the pen point so that said water absorber is internally suppliable with the water by absorption; and nsaid main body being provided at the rear end thereof with a communicating hole through which the rear end of said water absorber communicates with the outside. |
