  • Transparent varnish composition
    Patent number: 12466963
    Abstract: According to an example aspect of the present invention, there is provided a method of preparing a transparent varnish composition. The method comprises the steps of providing a binder, adding to the binder 1 to 40 wt % precipitated calcium carbonate particles by weight of the composition, wherein the precipitated calcium carbonate particles have an average D50 particle size of 60 to 120 nm measured by dynamic light scattering, fewer than 10% of the precipitated calcium carbonate particles by volume of the total precipitated calcium carbonate particles have a particles size of 75 nm or less, fewer than 10% of the precipitated calcium carbonate particles by volume of the total precipitated calcium carbonate particles have a particles size of 110 nm or more, the steepness of the particle size distribution is in the range of 1.3-1.55, and dispersing the precipitated calcium carbonate in the composition.
