Japanese Patent JP7373964
Kind Code:
B2
Abstract:
To provide a film containing a thermoplastic resin and a fibrous molding, in which an identification function can be sufficiently exhibited by the fibrous molding, and a security card, a passport, and a method for producing a film.SOLUTION: A film has (A) a thermoplastic resin and (B) a fibrous molding, the (B) fibrous molding containing a thermoplastic resin (b). When measured with a differential scanning calorimeter, the thermoplastic resin (b) shows at least one of a glass transition temperature T2[°C] and a melting point T3[°C]. When the temperature at which a melt viscosity of the (A) thermoplastic resin at a shear rate 1,216[1/s] is 500[Pa s], is defined as T1[°C], the temperature T1[°C], glass transition temperature T2[°C] and melting point T3[°C] satisfy at least one of the following formulae (1) and (2): (1) T2>T1-30 and (2) T3>T1+50.SELECTED DRAWING: Figure 1
