Photographic material. |
摘要 |
<p>A photographic material exhibiting improved photographic characteristics comprises a support having a layer of microcapsules thereon, and an image-forming agent being associated with the microcapsules. The microcapsules include a mixture of a first subset of microcapsules and a second subset of microcapsules. The first and second subsets of microcapsules are associated with an image-forming agent for the same colour. The first subset of microcapsules provide a higher film speed than the second subset of microcapsules when the first and second subsets of microcapsules are exposed to a broad band white light source and developed under identical conditions.</p> |
