Document Type and Number:
WIPO Patent Application WO/2007/010859
Kind Code:
A1
Abstract:
A cellulose ester film laminate comprising a cellulose ester film and a protective
film laminated on at least one surface of the cellulose ester film, the cellulose
ester film satisfying the requirements represented by the formulae (S-1) to
(S-3) and having a residual solvent of 0.01% by mass or less. By using the laminate,
a cellulose ester film having a good surface condition and no flaw can be provided.
Formula (S-1): 2.5 ≤ A+B ≤ 3.0; Formula (S-2): 0 ≤ A ≤
2.2; and Formula (S-3): 0.8 ≤ B ≤ 3.0 wherein A represents the degree
of substitution of a hydroxyl group in cellulose by an acetyl group; and B represents
the degree of substitution of a hydroxyl group in cellulose by an acyl group having
3 to 22 carbon atoms.
