The present invention relates to a process for the manufacture of a paper substrate suitable for incorporating silicone in a catalytic hydrosilation reaction and the product thereof, the paper substrate comprising a cellulose fibre based paper and a polymeric base coat, wherein the polymeric base coat comprises a polymer containing functional vinyl groups in an amount equal to or higher than 0.5 millimoles per gram of polymer, such that the surface of the polymeric base coat is hydrophobic. Advantageously, polybutadiene with a high vinyl content, obtainable by 1, 2-addition polymerization of 1, 3-butadiene, can be used in the polymeric base coat. |
