Document Type and Number:
Japanese Patent JP2020040399
Kind Code:
A
Abstract:
To provide a polyester film which is free of a remarkable yellowing, embrittlement, surface cracking, and severe deterioration of mechanical properties and optical properties in applications, and has permanent anti-fogging performance, transparency of 93% or more, and UV resistance of at least 5 years.SOLUTION: The present invention relates to a single-layered or multi-layered polyester film having a transparency of 93% or more, in which all of the film layers of the film contain a UV stabilizer, and the film has a permanent antifogging layer on at least one side thereof, and the permanent antifogging layer is a dried body of an aqueous coating dispersion. The aqueous coating dispersion contains a) 1 to 15 wt% (based on the aqueous coating dispersion) of an antifouling polymer and b) 3 to 15 wt% (based on the aqueous coating dispersion) of a hygroscopic porous material based on the applied dispersion. There are also provided a preparation method therefor and an application thereof.SELECTED DRAWING: None
