Zusammenfassung:PROBLEM TO BE SOLVED: To provide a cellulose ester film laminate capable of supplying the cellulose ester film having good face condition and no flaw with a small amount of charging. SOLUTION: The cellulose film laminate includes a releasable protection film made of a resin substrate and an adhesive layer having electrical conductivity of 1012Ω or less overlying one face of a cellulose ester film satisfying equations: 2.0≤A+B≤3.0, 0≤A≤2.5 and 0.5≤B≤3.0 and whose remaining solvent quantity is 0.01 mass% or less. In the equation, A and B respectively represent substituting rate acetyl groups to hydroxyl groups of the cellulose, and acyl groups with 3 to 22C. COPYRIGHT: (C)2008,JPO&INPIT
