The patent sets out a paper product comprising a paper substrate and a barrier coating with an alcohol-based binder and an inorganic particulate. The paper substrate could be coated or printed with the barrier coating composition.

In tests conducted, mineral oil transmission through the barrier coating found reduction in measured infrared (IR) intensity at 2920cm is less than 1%, as determined by attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy with the method described in the patent.
