The present invention provides the application of a tungsten-containing sensitizer in preparing a resin composition capable of laser-activated selective metallization, wherein the tungsten-containing sensitizer is selected from tungsten oxide, tungsten sulfide, tungsten-containing Any one or two or more of acids and tungsten-containing salts belong to the field of laser sensitization assistants. The inventors of the present invention unexpectedly found that, after activating the resin composition to which the tungsten sensitizer is added by using a laser with a wavelength of 190-1064 nm, the surface of the resin composition can be well electrolessly plated with copper. On the one hand, 190‑1064nm covers almost all laser wavelengths, and activating the resin composition at different laser wavelengths can take advantage of the laser wavelength itself; Sensitizing additives are cheaper and 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 tungsten-containing sensitizing assistant, and has excellent industrial application value. |
