  • Patent number: 7052540
    Abstract: Aqueous dispersions of carboxylated cellulose esters are disclosed having a low organic solvent content. These dispersions can be prepared using a volatile hydrophilic organic solvent and a coupling organic solvent having a lower volatility, the volatile hydrophilic solvent being substantially stripped off during preparation to obtain a dispersion useful in a variety of coating compositions, providing satisfactory performance in metallic flake control, flow and leveling properties, and defect reduction.

  • Patent number: 6773497
    Abstract: A cellulose acylate film formed from a solution of cellulose acylate contains a solvent of the solution at 0.1-0.6 wt. %, and acids at less than 500 ppm. The solvent is composed of at least one of esters and ketones, and further a recycled solvent recycled from the solution. In order to produce the cellulose acylate film, the solution is applied on a dope band moving in a direction, and dried to contain the solvent between 10-80 wt. % to the cellulose acylate. Thus a film-like material is formed from the solution, and peeled from the dope band. Thereafter the film-like material is further dried to form the cellulose acylate film containing the solvent at between 0.1 and 0.6 wt. %.
