Abstract: The present invention relates to image-formation on any selected kind of objective body. The characterizing features reside in such that, based upon fed image data, required images are formed on an image-transferable sheet acting for image carry-over service and in reliance on sublimation image transfer technique, and then, by the use of said sheet with said images thus formed thereon, the formed images thereon are transferringly applied on the objective body. By adopting the above measures, the objective body can be formed sharply and clearly with any desired images, irrespective of kind and configuration thereof, with such superior results of highly improved unity and solidability between the formed images and the objective body to be decorated with.

Abstract: A printed wiring board to suppresses invasion and occupation of insects having sensory nerves such as cockroaches and ants. Accordingly, it prevents malfunctioning of electronic appliances due to the presence of insects. It further avoids thickness fluctuation or blurring of the repellent layer of electronic material containing the repellent chemical. These printed wiring boards are warp-free and appear normal. A printed wiring board of the invention contains an electronic material formed on at least one of first and second surfaces of an insulating substrate. The electronic material contains a neurologically active insect and a binder. The electronic material forms a selective pattern.
