Since 1995, we have been taking part in “Yume Kagaku-21” sponsored by the Chemical Society of Japan, the Japan Chemical Industry Association and so on. This event is aimed at pupils so as to arouse their interest in ‘Chemistry’, and it takes place during their summer vacation. The events include a lot of chemical experiment show closely planned by ten or more chemical companies. We have demonstrated several experiments related to the chemistry of silver halide photography and they had a good reputation. Especially, the experiment of ‘Color Development’ used a photographic material having ultra low sensitivity in which an exposure and a development can achieve without the use of a dark room has been very popular among pupils. We will continue such activities in order to make silver halide photography more familiar and prevalent.
