PROBLEM TO BE SOLVED: To provide a copper-transition resistance agent for an electronic circuit board, which has a superior metal (copper) ion capturing property and is effectively used for a material to come in contact with the electronic circuit board. SOLUTION: The copper-transition resistance agent for the electronic circuit board comprises an alkyl vinyl ether additive of 1,3,5-triazine-2,4,6-trithiole. As the alkyl vinyl ether additive of 1,3,5-triazine-2,4,6-trithiole, a triazine derivative is used which has three SH groups each converted into an SCH(CH<SB>3</SB>)OR group (R group: an alkyl group having three or more carbon atoms).
