An adhesive composition comprises a miniature of a methanol-soluble nylon, an epoxy resin and a curing agent for the epoxy resin in an amount sufficient to harden the epoxy resin to a thermoset state. Specified nylons are an interpolyamide of hexamethylene diammonium adipate, hexamethylene diammonium sebacate and e -caprolactam and an N-alkoxyalkyl substituted 6:6 nylon. Specified epoxy resins are the polyglycidyl ethers of bis-phenol-A, resorcinol, glycerol, 1:1:2:2-tetra-kis-(4-hydroxyphenyl)ethane and novolaks and a compound of the formula The examples disclose curable compositions comprising:-(1) an interpolyamide of hexamethylene diammonium adipate, hexamethylene diammonium sebacate and e -caprolactam, water, methal, furfuryl alcohol, an epoxy resin derived from bis-phenol and epichlorhydrin and 2:4 - dihydrazino - 6 - methylamino - s - triazine, (2) silica, an N-methoxymethyl substituted 6:6-nylon, a liquid epoxide, a solid epoxide (both being reaction products of bis-phenol with epichlorohydrin and 2:4-dihydrazino-6-methyl-amino-s-triazine and (5) the interpolyamide of (1), an epoxidized novolak, diallyl melamine, water, methanol, methyl ethyl ketone and glass filaments.ALSO:In the examples: (1) and (3) a polyethylene coated kraft paper liner is coated with a solution comprising an interpolyamide of hexamethylene diammonium adipate, hexamethylene diammonium sebacate and -caprolactam, water, methanol, furfuryl alcohol, an epoxy resin derived from bis-phenol and epichlorhydrin and 2:4-dihydrazino-6-methylamino-s-triazine, and dried in an oven, the process then being repeated; (2) the solution of (1) is coated on a polyethylene coated kraft paper liner and dried, lightweight cotton scrim cloth and a composition comprising silica, an N-methoxy-methyl substituted polyhexamethylene adipamide, a liquid epoxide, a solid epoxide (both being reaction products of bis-phenol with epichlorhydrin) and 2:4-dihydrazino-6-methylamino-striazine applied, the adhesive being covered with a sheet of polyethylene; (4) the process of (3) is repeated but using an N-methoxymethyl polyhexamethylene adipamide in place of the interpolyamide; (5) a paper liner is coated with a composition comprising the interpolyamide as in (1), an epoxidized novolak, diallyl melamine, methanol, water, methyl ethyl ketone and glass filaments; (6) a paper liner coated as in (5) is further coated with a solvent-free blend of a bis-phenol-epichlorhydrin condensate and a boron-trifluoride-monoethanolamine complex; (7) and (8) a copper foil is coated with a composition comprising the interpolyamide of (1) an epoxidized novolak, methanol, water and diallyl melamine; and (9) a paper liner is coated with a bis-phenol-epichlorhydrin condensate and N:N-diallyl melamine.
