PURPOSE:To delicately adjust the color tone by using gold and ferric oxide or manganese as colorants and selecting the ratio between the thicknesses of the films of the two components. CONSTITUTION:When gold and ferric oxide are used as colorants, a multi- layered film having the structure of air/L/Au/L/Fe2O3/L/H/L/Fe2O3/L/Au/L/H/L/ H/g-lass (L is a transparent layer having a low refractive index and H is a transparent layer having a high refractive index) is formed. The ratio between the total thickness of the gold layers and that of the ferric oxide layers is 1:0.900 and the color density is arbitrarily changed by changing the total thickness of the gold layers by 0-21.28nm. When gold and manganese are used as colorants, a multilayered film having the structure of air/L/Au/L/Mn/L/H/L/ Mn/L/Au/L/H/L/H/glass is formed. The ratio between the total thickness of the gold layers and that of the manganese layers is 1:0.694 and the color density is arbitrarily changed by changing the total thickness of the gold layers by 0-21.28nm. By the combination of the two components, an original pink color tone having high absorption in a shorter wavelength range and relatively high absorption in a central wavelength range is obtd. |
