Abstract (en)

[origin: US4360590A] Novel gelatins which contain microgel, oligomers of alpha -gelatin, alpha -gelatin and not more than 25 percent by weight of fragments of alpha -gelatin (peptides) with a molecular weight of less than 9x104 are used as binders in layers of photographic materials. Photographic additives are readily compatible with the gelatins. Furthermore, the good viscosity characteristics and short setting times of the gelatins also facilitate the production of photographic materials.
