Abstract
By virtue of an activating pretreatment with a polymer-stabilized Pd sol, patterns, such as transparent patterns of indium-tin oxide, can be deposited on glass by electroless metallization. For example polyvinyl alcohol is used as the polymer.
Claims15
A method of metallizing only a pattern of a material other than glass provided on a glass substrate, said method comprising adding a reducing agent other than SnCl.sub.2 and a water-soluble polymer to an aqueous solution of a Pd salt to thereby form a stabilized Pd sol, bringing said pattern and glass substrate into contact with said stabilized Pd sol to thereby activate only said pattern, removing said glass substrate and the resultant activated pattern from contact with said stabilized Pd sol, rinsing said glass substrate and said activated pattern with water and then treating said glass substrate and said pattern with an electroless metallization bath to thereby metallize only said pattern.
A method of metallizing only a pattern of a material other than glass provided on a glass substrate, said method comprising adding a reducing agent other than SnCl.sub.2 and a polyvinyl pyrollidone to an aqueous solution of a Pd salt to thereby form a stabilized Pd sol, bringing said pattern and glass substrate into contact with said stabilized Pd sol to thereby activate only said pattern, removing said glass substrate and the resultant activated pattern from contact with said stabilized Pd sol, rinsing said glass substrate and said activated pattern with water and then treating said glass substrate and said pattern with an electroless metallization bath to thereby metallize only said pattern.
