Title: Improved manufacture of gelatin films for imbibition printing
IPC: G03C7/25
Filed: 1930-06-02
Abstract: A gelatin coating or film is hardened to render it uniformly dye-absorbent for the reception of dye-imbibition prints, by applying a hardening agent to the coating or film after it has set, but before it is dried.  The coating or film may be formed on a support, such as celluloid, glass, or paper, as by drawing one side of the support along the surface of a gelatin emulsion.  The hardening agent may be an aqueous solution of chrome alum in which the film is immersed for a brief period, and it may contain gelatin and a peptizing agent such as saponin to facilitate wetting of the coating or film.  The acidity of the chrome alum is preferably partially neutralized by the addition of ammonia. Reference is made to the hardening of gelatin coatings or films by adding bichromates and sulphurous acid, bisulphites &c. to the gelatin emulsion before coating, assisted by heating or exposure to light.  Specification 16785/88, [Class 98, Photography], is referred to.ALSO:A gelatine coating or film is hardened to render it uniformly dye-absorbent for the reception of dye-imbibition prints, by applying a hardening agent to the coating or film after it has set, but before it is dried.
