Abstract
Compositions useful as adhesives, sealants, laminating resins and coatings comprise PA0 (a) an epoxide resin PA0 (b) a nitrogen-containing latent curing agent for this resin, such as dicyandiamide or isophthalic acid dihydrazide and PA0 (c) as accelerator for the cure, and dispersed as a powder in (a) and (b), a solid solution of a nitrogen base having a boiling point above 130.degree. C. and a polymer of an unsaturated phenol. Typical nitrogen bases used in (c) include benzyldimethylamine, 2-methylaminoethanol, isophorone diamine triethylene tetramine, and 2-methylimidazole. Typical polymeric phenols include poly(p-vinylphenol).
