Abstract:
A phthalocyanine compound of the formula:MkPc(â€”Oâ€”Râ€”Oâ€”)x(â€”YR1) y(â€”Z)m(â€”SO3A)nâ€ƒâ€ƒ(1) wherein MkPc is a phthalocyanine nucleus of the formula: in which M is selected from the group consisting of hydrogen, lithium, sodium, copper, nickel, zinc, manganese, iron, chloro-iron, chloro-aluminum, tin, lead, vanadyloxy and titanyloxy, andk is the inverse of half the valency of M; R represents an unsubstituted naphthylene or phenylene group, or a naphthylene or phenylene substituted by one or more substituents selected from the group consisting of C1-20-alkyl, C1-20-alkoxy, C2-20-alkenyl, C1-20-alkenyl, C1-20-alkoxycarbonyl, hydroxyC1-4-alkoxy, phenyl, benzyl, phenylthio, fluoro, chloro, bromo, â€”CN, â€”NO2, â€”CF3, â€”COR2, â€”COOR2, â€”CONR2R3, â€”SO2R2, â€”SO2NR2R3, â€”NR2R3 andâ€”OR2 in which R2 and R3 each independently is â€”H, C1-4-alkyl or phenyl; Y represents oxygen or sulphur; R1 represents an unsubstituted alkyl, naphthyl or phenyl group, or an alkyl, naphthyl or phenyl group substituted by one or more substituents listed for the R group; Z represents a halogen or hydrogen; A represents hydrogen , alkaline earth metals, alkali metals, unsubstituted ammonium or ammonium substituted by from 1 to 4 substituents selected from the group consisting of C1-18-alkyl and phenyl, each said substituent being optionally substituted by one or more substituents listed for the R group; x represents an integer from 1 to 8; y represents an integer from 0 to 14; m represents an integer from 0 to 14; n represents an integer from 0 to 32; the sum of 2x, y and m not exceeding 16, the groups or atoms â€”Oâ€”Râ€”Oâ€”, â€”YR1 and Z are attached to the peripheral carbon atoms numbered 1 to 16 in Formula 2,and both of the O atoms in the â€”Oâ€”Râ€”Oâ€” group are bound to adjacent carbon atoms in the phthalocyanine nucleus, with the proviso that when n is zero, at least one naphthylene or phenylene group represented by R carries at least one alkyl group containing at least four carbon atoms.
