Ortho Amino Phenol
1. Zida zopangira utoto, zomwe zimagwiritsidwa ntchito popanga utoto wa sulfure, utoto wa azo, utoto waubweya ndi EB, etc. M'makampani ophera tizilombo, amagwiritsidwa ntchito ngati zopangira za phoxim.
2. Amagwiritsidwa ntchito makamaka popanga asidi mordant Blue R, sulfure yellow bulauni, etc. Angagwiritsidwenso ntchito ngati ubweya utoto.M'makampani opanga zodzoladzola, amagwiritsidwa ntchito popanga utoto wa tsitsi (monga utoto wolumikizira).
3. Kutsimikiza kwa siliva ndi malata ndi kutsimikizira kwa golide.Ndiwopakatikati mwa utoto wa diazo ndi utoto wa sulfure.
