The present invention provides the application of a zinc-containing sensitizing assistant in the preparation of a laser-activated selective metallization resin composition. The zinc-containing sensitizer is selected from any one or two or more of zinc oxides, zinc sulfides, zinc hydroxides, and zinc salts. The inventors of the present invention have unexpectedly found that, after using the resin composition containing zinc sensitizers and ultraviolet lasers with a wavelength of 190-395 nm, electroless copper plating can be performed well on its surface. On the one hand, compared with the traditional infrared laser, the ultraviolet laser has the advantage of higher activation accuracy; Inexpensive, can significantly reduce production costs. The present invention can obtain a resin composition with excellent coating thickness and coating strength under the condition of lower addition amount of zinc-containing sensitizing assistant, and the background color is light, which is especially suitable for light-color laser-activated selective metallization resin Products, with excellent industrial application value. |
