More Information
Summary:A reflective screen for a liquid crystal projector in an aircraft comprises a polarizing film provided with an anti-reflective member on its top surface and a reflective member on its bottom surface. The reflective member is bound to the polarizing film by a urethane resin adhesive, the anti-reflective member is bound either by a urethane resin adhesive or by an acrylic resin pressure sensitive adhesive. Moreover, a method of manufacturing such a reflective screen as a laminate is disclosed, comprising the steps of coating and drying a urethane resin system adhesive on a mat type polypropylene resin film, pressure bonding thereto a polarizing film made of a polyethylenterephtalate (PET) resin film, coating and drying on the other surface of said PET-film an acrylic resin system pressure sensitive adhesive and pressure bonding an aluminium alloy plate thereto.
