PURPOSE:To enhance adhesion between the photosensitive body and a color separating material by bonding a layer having the color separating function to a photosensitive layer by the medium of a polychloroprene adhesive. CONSTITUTION:The layer having the color separating function is bonded to the photosensitive layer by the medium of a polychloroprene adhesive, and this is the most widely used general purpose adhesive among the solvent solution type adhesives, and there are some types of it; 'Neoprene AF(R)', and the like. A heat seal type adhesive obtained from 'Neoprene HC(R)' forms a coat film free from tackiness at all at normal temperature, but this film exhibits very strong adhesion, when it is melted by heating. Accordingly, it is suitable for this adhesive, and a preferable thickness of this coat film is about 1mum to bond the photosensitive layer to the filter layer, and the thicker, the inferior in image sharpness at that part and the lower in image contrast. |
