The invention discloses an organic phosphonic acid sodium carboxylate developing accelerator and a preparation method thereof. The invention utilizes that the organic phosphonic acid sodium carboxylate developing accelerator has both sodium phosphonate and sodium carboxylate functional groups in the molecule, which can reduce the Dosage, the introduction of sodium phosphonate group is conducive to stabilizing the pH of the system after the decomposition of silver methyl benzotriazole salt, has the advantages of significantly reducing the development temperature and increasing the development density, while avoiding the existence of traditional single sodium carboxylate development accelerators. Disadvantages of fog. The development accelerator of the invention has simple production conditions, simple reaction treatment process, high yield, low cost and high implementation feasibility. |
