Abstract
An ink includes a solvent and a resin, wherein the storage elastic modulus G1 of an ink film obtained by drying the ink is 2.0×10-5.0×10Pa at 20 degrees C. as measured by a dynamic viscoelasticity measuring method and the ratio (G2/G1) of the storage elastic modulus G1 to the storage elastic modulus G2 of the ink film measured at 80 degrees C. by the dynamic viscoelasticity measuring method is 0.30-0.85.
