Morphology

photostable = stable (semi-transparent) = photo + stable

The meaning is compositionally clear from 'photo' meaning light and 'stable' meaning resistant to change, but the term is somewhat technical.

Etymology

The word photostable joins photo- meaning 'light', as in photograph, and stable meaning 'not changing', so it describes something that does not break down or lose its effect when it is in sunlight.
