れにおいても充分でない。The following can be seen from Table 1 above. (1) In Comparative Examples 1 and 2, (A) organic phosphine compound was not blended, but in both cases, the copper plate corrosion resistance was 3 (3b).
(2) Comparative Example 3 does not contain (B) an organic molybdenum compound, and this composition has a copper plate corrosion resistance of 1 ( l
It is good as a), but the amount of wear in the abrasion test is large. (
3) In Comparative Example 4, a metal deactivator was blended together with (B) an organomolybdenum compound, but (A) an organophosphine compound was not blended, so the copper plate corrosion resistance was 1(l).
It is good as a), but the amount of wear in the abrasion test is large. (
4) Comparative Example 5 did not contain (A) the organic phosphine compound, so the copper plate corrosion resistance and baking resistance were 9. It is not sufficient in terms of wear resistance.
