Abstract: PROBLEM TO BE SOLVED: To obtain an infrared-absorbing phthalocyanine, being the specific one, having extremely effective infrared-absorbing properties and useful as an infrared-absorbing agent for an infrared-absorbing ink, an printing ink, glasses, an agricultural sheet, a heat transfer printing, etc. SOLUTION: This infrared-absorbing phthalocyanine is the new one of formula I [A is a group of formula II (each of the rings B and C may be substituted by a 1-4C alkyl, a 1-4C alkoxy, nitro, hydroxysulfonyl, benzoyl or a benzene ring obtained by condensation cyclization at the ortho position; R is H or methyl), etc.; both Hs attaching to nitrogens may be replaced by copper, nickel, vanadyl, magnesium, AlCl, or zinc]. The infrared-absorbing phthalocyanine has an infrared absorption within a range of 720-1,100μm wavelength and is useful as an infrared-absorbing agent for an infrared absorbing ink, a printing ink, glasses, an agricultural sheet, a sheet-bonded plate glass, a heat transfer printing, etc. The compound is obtained by reacting compounds of formulas III and IV with a phthalocyanine substituted by a halogen.

Abstract: The invention relates to phthalocyanine of formula (I), wherein Me means twice hydrogen, twice lithium, magnesium, zinc, copper, nickel, VO, TiO, AlCl, AlOH, AlOCOCH3, AlOCOCF3, SiCl2 or Si(OH)2, at least four of the radicals R to R independently mean a five or six-membered saturated nitrogenous heterocyclic radical which is bonded to the phthalocyanine sceleton by a cyclic nitrogen atom and may contain other heteroatoms, and optionally, the remaining radicals R to R mean hydrogen, halogen, hydroxy sulfonyl or C1-C4 dialkyl sulfamoyl, with the exception of tetrakispiperidinyl phthalocyanine. The invention also relates to the use of phthalocyanines substituted by heterocyclic radicals for marking liquids such as mineral oils which contain phthalocyanines of this type.
