Idayi ezithile (ezithe ngqo, i-asidi, i-acidic medium, i-reactive, njl. njl.) zixutywe kunye ne-ion zetsimbi (i-cobalt, i-chromium, i-nickel ions) ukwenza udidi lwedayi. Ukukhanya kwelanga okanye ukuhlamba.Umzekelo, ukukhanya kwelanga ngokuthe ngqo kwi-emerald blue GL (i-Lionolblue GS) kunye ne-acid complex blue GGN (i-Acid Complex Blue GGN), njl.
1:2 Idayi zeMetal ezinoluhlu olubanzi lwezicelo, ezinokuthi zohlulwe zibe ngezantsi phantsi kokulandelayo:
a) Izicelo kwiingubo (iinki, iipeyinti).Umzekelo, umbala wokhuni, inki yokuprinta, umbala wesinyithi, njl.
b)Ukusetyenziswa kwiiplastiki, ikakhulu ezisetyenziswa njengombala ocacileyo (fluorescent) kwiiplastiki
c) usetyenziso olukhethekileyo, olufana nokufakwa imibala kwephepha lewax okanye imveliso yekhandlela, umbala wepolishi yezihlangu, umbala wokutshiza wesikhumba, izithambiso kunye neminye imibala.
1:2 Idayi zeMetal complex ziyidayi ezinyibilika kwizinyibilikisi zendalo ezifana nearomatics, esters, styrene, methyl methopropionate, njl.
I-shades eziphambili ze-1: 2 Idayi ze-Metal eziyinkimbinkimbi zezi: tyheli, i-orenji, ebomvu, eluhlaza okwesibhakabhaka, emnyama, kunye ne-fluorescent ebomvu (ipesika) .Kwakhona kukho idayi ye-Metal complex ebizwa ngokuba 'yi-China Red' kwimarike enemibala eqaqambileyo kakhulu.Ikwaziwa nangegama iflegi yeSizwe eBomvu.
