摘要 |
<p>The present invention concerns a method of producing a calendered, coated fibrous web, according to which method a fibrous web is coated with a coating colour containing a coating pigment, and the coated fibrous web is calendered. According to the invention, at least 1 % preferably 10 to 100 % of the weight of the pigment comprises calcium oxalate, and calendering the coated web by online calendering. The properties of the calcium oxalate pigment are so advantageous for calendering that it is possible to obtain a reasonably high gloss already with a machine calender (online calendering), which will eliminate need for a separate offline calender in the production line of matt surface papers. The invention further relates to the use of calciumoxalte as a pigment in silkpapers.</p> |
