Latest Patents

Outi Aho holds a patent for a filler and a process for its production. The patent describes a filler that comprises cellulose or lignocellulose fibrils, onto which light-scattering material particles have been deposited. The invention includes an alkyl derivative of cellulose, such as carboxymethyl cellulose (CMC), which is sorbed to the fibrils. This filler can be prepared from a source material containing cellulose or lignocellulose fibrils by forming a fibril suspension. The process involves feeding source materials that form an inorganic or organic salt, which precipitates to create a light-scattering pigment. The resulting filler exhibits excellent strength properties, particularly good bond strength, allowing for an increased concentration of mineral pigment in paper while reducing grammage without compromising other essential properties.
