Functional Dyes
● Porphyrin Series
▶ Properties
- It has narrow FWHM(Full width at the half-maximum), excellent solubility and durability.
▶ Application
- Optical disk material of DVD-R, Optical filter material of PDP
▶ Representative physical properties
● cyanine Series
▶ Properties
-By the number of Methine associated with conjugated double bonds that can be controlled easily absorption wavelengths are Polymethin series, Squarylium series, crocomium series, etc. There are various kinds. Also the excellent solubility, high absorption coefficient, so the information with records, information display and laser has been hailed as a functional pigment.
▶ Application
- Optical disk material for DVD-R, Optical filter material of PDP, Solar battery sensitive material.
