ABSTRACT:
The present invention relates to an anti-migratory (as respects impregnated porous sheet members) phenol-formaldehyde resole resin in water emulsions. The emulsion is rendered anti-migratory (when impregnated into paper) through the addition thereto of an anti-migratory agent selected from the group consisting of polyelectrolytes, certain salts of inorganic acids, and combinations thereof. The composition is especially useful in the impregnation of filter paper.
