Patent ID: 8410244

Claim:
A vibration damping film comprising a resin composition obtained by dispersing titanium dioxide (Y) and mica flakes (Z) in a polyester resin (X) composed of a dicarboxylic acid constitutional units and a diol constitutional units, wherein said resin composition satisfies all of the following conditions (I) to (III), and wherein the film has a thickness in the range of 20 to 200 μm: (I) Content of polyester resin (X), titanium dioxide (Y) and mica flakes (Z) in the resin composition is in the range of 35 to 60% by mass, in the range of 5 to 15% by mass and in the range of 30 to 55% by mass, respectively, (II) Average particle diameter of the mica flakes (Z) in the resin composition is in the range of 5 to 80 μm, and (III) Elongation at failure point of the resin composition measured according to JIS K7127 is in the range of 30 to 70%.
