摘要:
In a cellulose acylate solution, cellulose acylate is dissolved in an essentially non-chlorinated solvent. The essentially non-chlorinated solvent is a mixture of a ketone having a solubility parameter of 19 to 21 and an ester having a solubility parameter of 19 to 21. The solution further contains a releasing agent.
