  • Patent number: 11958953
    Abstract: A hard coating film may include a substrate and a hard coating layer provided on at least one surface of the substrate, in which, when the hard coating film is folded and unfolded 200,000 times with a bending radius of 1 mm in the direction in which the hard coating layer is oriented inwards under 60° C. and 90% relative humidity (RH), breakage does not occur, and the amount of change in transmission b* (chromaticity) of the film after UV irradiation for 100 hr using a 15 W UV-B lamp is 1.5 or less. The hard coating film may exhibit superior anti-curling properties, superior bending resistance under high-temperature and high-humidity conditions, and high light resistance, and can thus be applied not only to an image display device but also to a window for a flexible display device.

  • Patent number: 11760898
    Abstract: The present invention relates to a hard coating film including a substrate and a hard coating layer provided on at least one surface of the substrate, in which the hard coating layer includes a fluorine-based UV-curable-functional-group-containing compound, a conductive polymer, and a solvent, the conductive polymer being included in a specific amount, and the surface roughness (Ra) value of the hard coating layer is 1 nm or less, whereby the hard coating film can simultaneously exhibit hard coating performance and antifouling performance even in the form of a single layer not including a separate antifouling layer, and is remarkably improved in an antifouling effect based on the low surface roughness thereof due to the absence of inorganic fine particles, and the improved antifouling effect can be effectively maintained even in the presence of variously changing environmental conditions, and to a window and an image display device using the same.

  • Patent number: 11613658
    Abstract: The present invention relates to a hard coating film including a substrate and a hard coating layer provided on at least one surface of the substrate, in which the hard coating layer includes a cured product of a hard coating composition containing a fluorine-based UV-curable-functional-group-containing compound, dendritic acrylate, a conductive polymer, and a solvent, the conductive polymer being included in a specific amount, whereby the hard coating film is applicable to a flexible display device and can simultaneously exhibit hard coating performance and antifouling performance even in the form of a single layer that does not include a separate antifouling layer, and in particular, the high antifouling effect can be maintained even in the presence of variously changing environmental conditions, and to a window and an image display device using the same.

  • Publication number: 20230051118
    Abstract: The present disclosure relates to a hard coating film capable of providing excellent durability, elastic recovery rate, and abrasion resistance, by including a base layer; a first hard coating layer formed on at least one surface of the base layer and including a fluorine-based UV-curable functional group-containing compound; and a second hard coating layer formed between the base layer and the first hard coating layer and including inorganic particles; and an image display device including the hard coating film.
