Innovation Solution
A composition comprising polymer resin and a non-conductive metal compound represented by Cu3-xMxP2O8, where M is Zn and x is between 0 and 3, is irradiated with electromagnetic waves to form metal nuclei, enabling the formation of a conductive pattern through electroless plating without degrading the resin.

Engineering Contradiction Analysis
1Manufacturing precision
If conventional methods (metal layer deposition + photolithography or conductive paste printing) are used to form conductive patterns, then conductive patterns can be formed on polymer resin substrates, but the process becomes excessively complicated and it becomes difficult to form satisfactory fine conductive patterns
Solution Approach 1:
The invention segments the complex conventional process into a simplified two-step process: (1) incorporating non-conductive metal compound particles into the polymer resin substrate, and (2) irradiating with electromagnetic waves to selectively form metal nuclei and subsequent conductive patterns. This segmentation eliminates the need for metal layer deposition and photolithography, reducing process complexity while maintaining pattern fineness.
Solution Approach 2:
The invention applies preliminary action by pre-incorporating non-conductive metal compound particles (such as copper phosphate, zinc phosphate) into the polymer resin substrate before pattern formation. These particles are strategically positioned throughout the substrate, ready to be converted into conductive patterns only when electromagnetic wave irradiation is applied to specific regions, enabling simplified on-demand pattern formation.
2Ease of manufacture
If specific inorganic additives are included in resin for electromagnetic wave irradiation to form conductive patterns, then the process is simplified, but the inorganic additives influence the properties of the resin and the obtained polymer resin product has poor properties
Solution Approach 1:
The invention applies local quality by using non-conductive metal compound particles that remain inert and do not affect resin properties under normal conditions. Only when electromagnetic wave irradiation is applied to specific local regions do these particles convert into conductive metal nuclei, creating conductive patterns only where needed. This localized activation preserves overall resin quality while enabling simplified conductive pattern formation.
Solution Approach 2:
The invention utilizes parameter changes by altering the physical and chemical state of the non-conductive metal compound particles through electromagnetic wave irradiation. The particles transition from a non-conductive state (when incorporated into the resin) to a conductive metallic state (after irradiation), enabling controlled pattern formation without permanently degrading resin properties. The irradiation parameter (electromagnetic wave energy) triggers this selective transformation.
3Ease of manufacture
If specific inorganic additives are included in resin for electromagnetic wave irradiation, then conductive patterns can be formed by simplified process, but it becomes difficult to realize various colors in the resin products
Solution Approach 1:
The invention extracts the color-determining function from the inorganic additives themselves. Instead of relying on the intrinsic color of additives like copper phosphate or zinc phosphate, the invention uses these materials solely for their electromagnetic wave response properties. Color is then independently controlled through separate coloring agents or pigments added to the polymer resin, enabling both simplified conductive pattern formation and color variety without interference between functions.
