  • Publication number: 20200055280
    Abstract: The present invention provides an antifog laminate configured to be attached to an information acquisition region of a windshield that includes a laminated glass that is located opposite to an information acquisition device for acquiring information from the outside of a vehicle by emitting and/or receiving light, at least a portion of the laminated glass being curved, and the laminated glass having at least one information acquisition region through which the light passes, the antifog laminate including an antifog sheet including a sticky layer, a substrate film, and an antifog layer that are layered in this order, a sheet-shaped protective material that removably covers the antifog layer and is larger than the antifog layer, and a first protective sheet that removably covers the sticky layer.

  • Patent number: 10106458
    Abstract: Provided is a method for producing a vehicle window glass, the method being adapted to prevent peeling-off of a functional thin film from a ceramic shielding layer without masking the ceramic shielding layer with a masking tape. This production method includes: an application step of feeding a coating liquid for forming the functional thin film onto a principal surface of a glass sheet on which the ceramic shielding layer has been formed beforehand, so as to allow the coating liquid to flow in a predetermined direction on the principal surface; and a drying step of drying the fed coating liquid. In the application step, the glass sheet is set in such a position that the predetermined direction coincides with a first direction in which the maximum length of the principal surface is 30 cm or less (rather than with a second direction in which the maximum length is more than 50 cm) and thus that the distance the coating liquid flows on the principal surface is limited to 30 cm or less.
