    Abstract: A photographic paper comprising an outer-most layer comprising a hydrophilic colloid binder and colloidal silica, wherein : (i) the weight ratio of colloidal silica to hydrophilic colloid binder in said layer is 0.3:1 to 3:1; and (ii) the colloidal silica has a mean particle size of 2 to 10 nm. The photographic papers have low stickiness rendering them suitable for storage before use and also after use in album-books where the photographic papers are in face-to-face contact.

    Abstract translation: 一种照相纸,其包含最外层,其包含亲水胶体粘合剂和胶体二氧化硅,其中:(i)所述层中胶体二氧化硅与亲水胶体粘合剂的重量比为0.3:1至3:1; 和(ii)胶态二氧化硅的平均粒度为2〜10nm。 照相纸具有低粘性,使它们适合于使用前的储存,也可以在使用相册的照相纸进行面对面接触后使用。
