Abstract

A method for manufacturing a laminate, the method comprising a process of forming a silver-particle layer on a substrate, the process comprising allowing an aqueous solution of ammoniacal silver nitrate to contact with an aqueous solution of a reducing agent, and the aqueous solution of a reducing agent comprising a phenol compound as the reducing agent.

Claims (9)

1. A method for manufacturing a laminate, the method comprising a process of forming a silver-particle layer on a substrate, the process comprising allowing an aqueous solution of ammoniacal silver nitrate to contact with an aqueous solution of a reducing agent, and the aqueous solution of the reducing agent comprising a phenol compound as the reducing agent, an alkaline substance and an amine compound, wherein the silver-particle layer has a surface resistivity of 10 5 Ω/□ or more.

2. The method for manufacturing a laminate according to claim 1 , wherein the phenol compound comprises a benzene diol compound.

3. The method for manufacturing a laminate according to claim 1 , which is directed to manufacture of a component for an automobile.

4. The method for manufacturing a laminate according to claim 1 , wherein the phenol compound comprises hydroquinone.

5. The method for manufacturing a laminate according to claim 1 , wherein the alkaline substance comprises sodium hydroxide or potassium hydroxide.

6. The method for manufacturing a laminate according to claim 1 , wherein the amine compound is an amino alcohol.

7. A method for manufacturing a laminate, the method comprising a process of forming a silver-particle layer on a substrate, the process comprising allowing an aqueous solution of ammoniacal silver nitrate to contact with an aqueous solution of a reducing agent, and the aqueous solution of the reducing agent comprising a phenol compound as the reducing agent, an alkaline substance and an amine compound.

8. The method for manufacturing a laminate according to claim 7 , wherein the alkaline substance comprises sodium hydroxide or potassium hydroxide.

9. The method for manufacturing a laminate according to claim 7 , wherein the amine compound is an amino alcohol.
