AI Technical Summary
Technical Problem
In existing technologies, the stability of electroplating silver solutions is poor, resulting in uneven metal deposition and insufficient thickness, and the cost is high, making it difficult to achieve high-quality electroplating silver deposition.
Method used
Silver electroplating is performed using a stable composition containing metal salts, reducing agents, and stabilizers via a non-electrochemical method. Specific formulations and controlled parameters ensure long-term stability of the solution and high-quality deposition.
Benefits of technology
It achieves long-term stability and high-quality deposition of electroplated silver solution, with a deposition thickness of more than 1 micrometer, reduces costs, and improves the uniformity and thickness of deposition.

Abstract
This invention provides a composition for depositing metals on a surface under electroless and non-electrochemical conditions. It also provides a method for depositing metals, particularly under electroless conditions. [Solution] A solution (S) comprising at least one metal salt (M), a reducing agent (R) that enables the reduction of the metal salt (M), and a stabilizing additive (T) of formula (F1) is described: TIFF2026113538000009.tif35170 [In the formula, Ra, Rb, and Rc groups independently represent an alkane, alkene, or alkyne, which may be linear, branched, or cyclic and contain 1 to 20 carbon atoms; and Rd and Re groups independently represent a hydrogen atom or an alkane, alkene, or alkyne, which may independently be linear, branched, or cyclic and contain 1 to 20 carbon atoms].
