摘要 |
<p>The present invention relates to method of forming a transparent and gas-permeability decreasing coating by virtue of applying a coating containing at least one polymer dispersion on a sheet of paper, board or similar cellulosic fiber based web in at least one coating step. The method according to the invention is based on the use of a polymer dispersion containing extremely pure talc particles having a degree of purity of 90-100% and a particle size of 90% smaller than 40 mum.</p> |
