a group of green and blue organic colouring matters, used mainly as pigments and formed by condensation polymerization of four molecules of phthalonitrile with one atom of a metal such as copper phthalocyanine. Widely used in almost all pigmented products. Green: consists of halogenated copper phthalocyanine, and available in a number of shades from deep blue-green to a bright green with only a slight blue tone., PHTHALOCYANINE (pronounced thal-o-sy-a-nene)
This dye (almost a clear yellow-green) produces discs that appear gold or greenish gold. We presume that this is based on a gold reflective layer and that a silver reflective layer would produce a silver or greenish-yellowish silver disc.
When the recording laser heats the phthalocyanine dye it causes it to melt. As it melts the polycarbonate layer below the dye expands to fill the gap. This melted "blob" effectively diffuses the light enough to resemble the pits on a replicated CD., ftalotsüaniinvärvaine - sünteetiline värvaine, ftalotsüaniini derivaat. Tehnikas on tähtsaim ftalotsüaniini ja vase kompleksühend - helesinine ftalotsüaniinpigment. Selle soola kloorimisel saadakse roheline ftalotsüaniinpigment, sulfoneerimisel vees lahustuv türkiissinine valguskindel otsene ftalotsüaniinvärvaine. Ftalotsüaniinvärvainetel on väga kirgas värvus ja hea värvimisvõime, ta on kuumuskindel, erakordselt valguskindel ning püsiv hapete ja leeliste toime suhtes. Ftalotsüaniinvärvainetega värvitakse sünteetilisi kiudaineid, plastmasse ja kummit, vees lahustuvate ftalotsüaniinvärvainetega villast, siid- ja puuvillriiet.
