    Abstract: The invention discloses a paperboard comprising a base ply, a top ply, and an intermediate layer disposed in-between the at least one base ply and the top ply. The intermediate layer comprises pigment and microfibrillated cellulose (MFC).The application of an intermediate layer comprising pigment and MFC inbetween the base ply and the top ply gives rise to improved optical properties of the paperboard, even when using an uncoated top ply having a low grammage. This makes it possible to reduce the grammage of the top ply and still obtain good optical properties.
