<P>PROBLEM TO BE SOLVED: To provide a cellulose ester film laminate extremely reduced in the residual amount of a solvent, suppressed in discoloration and having no gelled substance therein. <P>SOLUTION: The cellulose ester film laminate is characterized in that the residual amount of the solvent is below 0.01 mass% and constituted by providing an ultraviolet absorbing layer, of which the transmittance of ultraviolet rays with a wavelength of 360 nm is 10% or below, at least on one side of a cellulose ester film satisfying the formula (S-1): 2.5≤A+B≤3.0, the formula (S-2): 0≤A≤2.2 and the formula (S-3): 0.8≤B≤3.0 (wherein A is a degree of substitution of an acetyl group with respect to the hydroxy groups of cellulose and B is a degree of substitution of a 3-22C acyl group with respect to the hydroxy groups of cellulose). <P>COPYRIGHT: (C)2007,JPO&INPIT |
