Foam compositions for surface application to fibrous substrates. |
摘要 |
<p>Rosin-based foams suitable for surface application to fibrous substrates such as paper and paperboard are obtained by aerating an aqueous solution having a pH of at least 8 and containing 0.1 to 5% of a water-soluble salt of rosin or fortified rosin and 0.02 to 5% of a water-soluble, amine-containing polymer compatible with the salt, the weight ratio of the salt to the polymer being within the range of 1:1 to 25:1. </p> |
