Compositions are disclosed which are particularly useful as mask adhesives in image-recording elements such as instant photographic products. These compositions comprise a polymeric acidic component having at least 3 milliequivalents of acid per gram of polymer, and a substantially immobile, blocked photographic development restrainer or a substantially immobile, blocked competing photographic developer. In image-recording elements, these compositions provide mask adhesives that form high strength permanent bonds while greatly improving border quality around image areas after imagewise exposure and development.
本发明公开了在即时摄影产品等图像记录元件中用作掩膜粘合剂特别有用的组合物。 这些组合物包括每克聚合物至少含有 3 毫当量酸的聚合酸性成分,以及基本不移动、阻断的感光显影抑制剂或基本不移动、阻断的竞争性感光显影剂。 在图像记录元件中,这些组合物提供的掩膜粘合剂可形成高强度的永久性粘合,同时大大提高图像曝光和显影后图像区域周围的边框质量。
