Normally solid shaped body, at least part of which is coated with a self-adhesive coating comprising a water-insoluble salt of collagen (I). (I) is microcrystalline, and colloidal, and at least 10% wt. of the salt is formed of bundles of tropocollagen units in aggregate form, the bundles having particle dimension is not >1 mu, and minimum diameter 25 Angstroms. The coating opt. contains a crosslinking agent for collagen, and a photosensitive material. The shaped body may be fibrous, e.g. paper, or non-fibrous, e.g. of cellulosic material. This form of collagen may be used as intermediate coating for the production of moisture-resistant cellulosic films, as it adheres exceptionally well and accepts coatings and moisture-resistant films, e.g. nitrocellulose coatings. In this case the collagen acts as fixing agent. |
