ndi
Mitundu ina (yachindunji, asidi, sing'anga ya acidic, yotakasuka, ndi zina zotero) imapangidwa ndi ayoni achitsulo (cobalt, chromium, nickel ions) kuti apange gulu la mitundu ya utoto. Kuwala kwa dzuwa kapena kuchapa.Mwachitsanzo, kuwala kwa dzuwa kolunjika kwa emerald blue GL (Lionolblue GS) ndi acid complex blue GGN(Acid Complex Blue GGN), etc.
1: 2 Metal complex dyes ali ndi ntchito zosiyanasiyana, zomwe zitha kugawidwa m'munsimu motere:
a) Kugwiritsa ntchito zokutira (ma inki, utoto).Mwachitsanzo, utoto wamatabwa, inki yosindikiza, utoto wachitsulo pamwamba, etc.
b) Kugwiritsa ntchito mapulasitiki, omwe amagwiritsidwa ntchito kwambiri ngati utoto wowonekera (fluorescent) wamapulasitiki
c) ntchito zapadera, monga pepala la sera kapena zopangira makandulo, utoto wopaka utoto wa nsapato, utoto wopopera wachikopa, zodzoladzola ndi mitundu ina.
1: 2 Metal complex dyes ndi utoto womwe umasungunuka mu zosungunulira za organic monga aromatics, esters, styrene, methyl methopropionate, etc.Ma organic solvents omwe atchulidwa pamwambapa amakhala pafupifupi osasungunuka m'madzi.
Mithunzi yayikulu ya 1: 2 Metal complex dyes ndi: chikasu, lalanje, wofiira, buluu, wakuda, ndi wofiira wa fulorosenti (pichesi) .Komanso pali utoto wa Metal complex wotchedwa 'China Red' pamsika ndi mitundu yowala kwambiri.Amadziwikanso ndi dzina loti National Flag Red.
