A curable composition comprising, consisting of, or consisting essentially of a) an epoxy component comprising a dinaphthalene epoxy having the structure wherein each R1 group is independently a C1-C20 hydrocarbon; a is an integer in the range of from 0 to 6; m is an integer in the range of 0 to 5; and b) a hardener component comprising i) a naphthol novolac which is a reaction product of I) from 1 to 99 weight percent 1-naphthol and II) from 1 to 99 weight percent 2-naphthol; ii) a phosphorus-containing composition which is the reaction product of an etherified resole with 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide; and iii) optionally a phenolic resin selected from the group consisting of a molecule having at least one substituted or unsubstituted naphthalene ring, a high functionality phenolic resin, and combinations thereof, is disclosed. The curable composition can be used to prepare prepregs and electrical laminates. |
