Definitions
- the present invention relates to new photographic material which contains UV absorbers, in particular of the bis-2-hydroxyphenyltriazinyl type.
- a group of triazine UV absorbers has now been found which, surprisingly, has proven to be largely free from such disadvantages. They show improved stability to natural light and have the property of better protecting image dyes and color couplers against exposure to light than was possible with the hydroxyphenylbenztriazoles and triazines commonly used in photographic materials.
- this group of triazines is suitable for increasing the stability of the magenta and cyan layers of photographic materials, e.g. in layers, which are applied over the magenta or cyan layer, or directly embedded in the cyan layer.
