Abstract
Abstract A method for producing a copper film-formed molding is disclosed, comprising a coating a mixed solution containing at least one copper compound selected from copper hydroxide and organic acid copper salts and a polyhydric alcohol as essential components on the desired area of an article having a heat deflection temperature of at least 165° C., and heating to a temperature of from 165° C. to the heat deflection temperature of the article and maintaining at this temperature in a non-oxidizing atmosphere.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
106 words
A method for producing a copper film-formed molding which comprises coating a mixed solution consisting essentially of a copper compound selected from the group consisting of copper hydroxide and organic acid copper salts and a polyhydric alcohol on the desired area of an article having a heat deflection temperature of at least 165° C., and then heating and maintaining the article at a temperature of from 165° C. to the heat deflection temperature of the article in a nonoxidizing atmosphere, wherein the mixed solution consists essentially of 10 to 70% by weight of the copper compound and 90 to 30% by weight of the polyhydric alcohol.
Claim 2
Independent Claim
106 words
A method for producing a copper film-formed molding which comprises coating a mixed solution consisting essentially of a copper compound selected from the group consisting of copper hydroxide and organic acid copper salts and a polyhydric alcohol on the desired area of an article having a heat deflection temperature of at least 165° C., and then heating and maintaining the article at a temperature of from 165° C. to the heat deflection temperature of the article in a nonoxidizing atmosphere, wherein the mixed solution consists essentially of 10 to 70% by weight of the copper compound and 90 to 30% by weight of the polyhydric alcohol.
Claim 3
Dependent Claim
30 words
