Here are some other options:
* Banggaan ng interes - This is a more literal translation, meaning "collision of interests".
* Pagkakasalungatan ng interes - This emphasizes the conflicting nature of the interests.
* Salungatan ng kapakanan - This emphasizes the conflict in terms of welfare or well-being.
The best translation will depend on the specific context. For example, "salungat na interes" is generally the most appropriate for formal situations, while "banggaan ng interes" might be better for informal situations.
