A selfbonding enamel containing resins with nucleophilic groups as well as possibly amide group-containing resins which are capable of crosslinking with one another, comprising (A) 5 to 95 wt% of at least one resin with nucleophilic groups selected from the group consisting of OH, NHR, SH, C(O)NHR, carboxylate, CH-acidic groups and Carbanions, (B) 0 to 70 wt% and optionally, 1 to 70 wt% of at least one amide group-containing resin and (C) 0 to 30 wt% and optionally, 1 to 30 wt% of at least one polyurethane resin, (D) 0 to 30 wt% and optionally, 1 to 30 wt% of at least one epoxy resin, (E) 5 to 95 wt% of at least one organic solvent, wherein the resins of either component (A) and/or, if component (B) is contained in the composition, component (B) contain a-carboxy-beta-oxocycloalkyl carboxylic acid amide groups and the percent by weight of (A)-(E) adds up to 100 percent; the coatings of the selfbonding enamel have excellent adhesion to electrically conductive wires and high sticking properties as well as provides high re-softening temperatures. ® KIPO & WIPO 2009 |
