ABSTRACT OF THE DISCLOSURE Vinyl dispersion coating compositions comprising (A) 10-40 parts by weight particulate vinyl resins (B) 5-80 parts by weight liquid plasticizer; (C) 1-20 parts by weight adhesion promotor comprising (i) a the thermoplastic phenol- formaldehyde condensate made with molar excess of the phenol and (ii) a compound that provider low molecular weight di- functional linking moieties with increase in temperature, wherein the molar ratio of the linking moieties releasable by (ii) to the total of hydrogen substituted ortho and para positions in (i) is at least about 3:4, preferably 1:1 or greater, and the weight ratio of (A) to (C) is about 40:1- 1:1. Preferred plastisol sealing compositions can exhibit improvements in adhesion to hydrophillic surfaces such as glass by as much as up to five times or greater than with conventional adhesion promotors. - 1 -
