    "protocol": "1. Prepare an aqueous coating composition containing water-soluble organic polymers, such as Bermocoll E230FQ (ethyl hydroxyethyl cellulose). The cellulose should be present in an amount of between 0.1 and 0.5 wt%, preferably about 0.2 wt%. 2. Include colloidal silica nanoparticles (e.g., Nalco 2326, 5 nanometers mean particle size, pH 10.5, 15% solid content) in the coating composition at an amount between 5 and 20 wt%, desired at about 15 wt%. 3. Add a surfactant such as Masil SF-19 or Surfactant 10G at a concentration of 0.05 to 0.15 wt%, preferably about 0.1 wt%. 4. Ensure the aqueous solution contains at least 75 wt% water, preferably de-ionized (DI) water, with some embodiments containing at least 90 wt% or 96 wt% water. 5. Oxidize the PET film prior to applying the aqueous coating using corona or plasma glow discharge at 2 to 10 watt/((ft²/min)/side) to enhance coating receptivity. 6. Apply the coating composition to the PET surface using bar, roll, knife, curtain, print, spray, slot-die, or dip-coating techniques. 7. Dry the coated substrate in an oven at a temperature of from about 20°C to about 150°C, preferably from about 50°C to 120°C, or from about 100°C to 110°C. 8. Aim for an average coating thickness between 90 to 140 nanometers to minimize glare and achieve desired optical properties. 9. The final coating should consist of at least 50 wt% water-soluble organic polymers, ideally at least 75 wt% or 90 wt%.The coating compositions were applied to clear polyester film by initially dispersing the ingredients in deionized water. The resulting dispersion was thoroughly mixed at a temperature of less than 45 degrees C. (or ambient temperature) until a clear solution was obtained. The coating was applied sequentially, one side at a time, with drying conducted in a hot air convection oven at about 110 degrees C. for typically about 1 minute or until constant weight."
