Benzimidazole derivative and composition for treating copper and copper alloy surfaces comprising the same |
摘要 |
A novel benzimidazole derivative is disclosed. The benzimidazole derivative is represented by the following formula (I), <IMAGE> (I) wherein R1 is a hydrogen atom, a lower alkyl group, or a halogen atom; R2 is a hydrogen atom or a lower alkyl group; R3 is an alkylene group with 1 to 18 carbon atoms; and n and m are integers from 0 to 3. The compound has an excellent rust preventing effect and can be used as a component of a composition for the treatment of surfaces of copper and copper alloys comprising the benzimidazole derivative which is particularly useful in preventing rust in printed-wiring boards.
