description Paper is made from paper stock containing pulp derived from recycled paper fibers by adding to the paper stock, an effective amount of an additive for reducing the deposition of contaminants, the additive one or more silicon containing material(s) selected from the group of: (i) an epoxy and/or glycidoxy functional silane, and/or hydrolysed or condensation reaction products thereof with water, (ii) glycidoxy and/or epoxy functional siloxane and/or hydrolysed or condensation reaction products thereof with water, (iii) a quaternary ammonium functional silicone polymer, and/or hydrolysed or condensed reaction products thereof with water and/or (iv) a quaternary ammonium functional silicone polymer cross-linked by an organic epoxide and/or hydrolysed or condensed reaction products thereof with water and/or (v) an amino functional silane and/or an amino functional silicone and/or hydrolysed or condensed reaction products thereof with water and/or (vi) an alkyl functional silane and/or hydrolysed or condensed reaction products thereof with water; The additive is preferably added in an amount of 0.01-10 percent by weight based on the dry weight of the paper stock.
