Abstract
A cross-linking agent as well as a preparation method and the use thereof is disclosed. The structure of the cross-linking agent contains a triazolyl, and contains a double bond, an amide acid, or an imide structure at the same time. The cross-linking agent is added into a resin composition, so that the film-forming property can be improved, the adhesion between the cured resin and a copper or copper alloy base material is improved, the discoloration of the copper or copper alloy base material is inhibited, and meanwhile, the resin has better heat resistance and chemical resistance after curing. The problem of poor compatibility caused by excessive additive types is avoided, and meanwhile, the problem of excessive additives may be relieved.
