Use of a mill-based composition comprising microfibrillated cellulose and co-processed inorganic particulate material as primary pigment and / or extender pigment, wherein said inorganic particulate material is co-processed with a fibrous substrate comprising cellulose during the preparation of said microfibrillated cellulose , further comprising primary pigment and / or extender pigment other than the co-processed inorganic particulate material wherein the extender pigment is one or more of kaolin, calcium carbonate and talc, wherein the microfibrillated cellulose has a d50 that varies from approximately 5 μm to approximately 500 μm, measured by laser light scattering, and wherein the microfibrillated cellulose has a 100 * d30 / d70 fiber tilt of 20 to 50, measured as described herein as a rheology modifier of a paint composition, wherein the microfibrillated cellulose is present in an amount ranging from 0.1% to 10% by pe so based on the total weight of the paint composition formulated from said grind base, wherein the grind base is free of cellulose-derived rheology modifier other than microfibrillated cellulose. |
