The novel features are that: (a) not less than 50 wt.% of the pigment is a natural ground CaCO3; (b) all the pigment has a fineness of not less than 80% being less than 2 mu m; and (c) the dry binder fraction is less than 13 wt.% with respect to the pigment. Also claimed is a method of making the paper.
