  • Hardcoat film, method for producing same, and display device
    Patent number: 12384896
    Abstract: A hard coat film includes a transparent resin film and a hard coat layer disposed on one surface thereof, the hard coat layer being composed of a cured product of a hard coat composition. The thickness of the hard coat layer 0.15 times or more the thickness of the transparent resin film. The hard coat composition has a negative cure shrinkage ratio. The absolute value of the amount of curl of the hard coat film cut into a 100 mm×100 mm square is 20 mm or less. The hard coat layer may contain a cured product of a polyorganosiloxane compound having an alicyclic epoxy group.

  • HARD COAT COMPOSITION, HARD COAT-EQUIPPED POLYIMIDE FILM, METHOD FOR MANUFACTURING THE SAME, AND IMAGE DISPLAY DEVICE
    Publication number: 20210179795
    Abstract: A hard coat-equipped polyimide film has a hard coat layer (2) on a principal surface of a transparent polyimide film (1). A hard coat composition for polyimide film contains a siloxane compound having an alicyclic epoxy group. The hard coat composition may contain fine particles. The hard coat-equipped polyimide fin is obtained by coating the hard coat composition on a principal surface of a transparent polyimide film and curing the hard coat composition by applying an active energy ray.
