摘要:
Disclosed herein is a method for recovering binder resin from the ink layer of ink ribbon, said method comprising collecting ink ribbon having an ink layer consisting of dye and binder resin, dissolving the ink layer of ink ribbon in a solvent in which dye and binder resin are soluble, freeing the resulting solution of insoluble matter, concentrating the solution, pouring the resulting concentrate into a solvent in which dye is soluble but binder resin is substantially insoluble, thereby precipitating binder resin, and separating and drying precipitates. By concentrating the solution remaining after precipitation of binder resin and drying the concentrate, it is possible to recover dye. Disclosed also herein is an apparatus for recovering dye and binder resin according to said method.
