Abstract
Abstract A novel metalo-phthalocyanine or an alkyl ester thereof in which each of two benzene nuclei of the four benzene nuclei condensed in the phthalocyanine ring has a carboxyl or alkoxy carbonyl radical attached thereto is well compatible with an organic polymer and thus provides an electroconductive polymer composition which may be formed into films or suitable articles.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
52 words
An electroconductive composition comprising (a) an electroconductive amount of 20-99% by weight of a metalo-phthalocyanine or an alkyl ester thereof in which each of two benzene nuclei of the four benzene nuclei condensed in the phthalocyanine ring has only one carboxyl or alkoxy carbonyl radical attached thereto, and (b) an organic polymer.
Claim 2
Dependent Claim
52 words
An electroconductive composition comprising (a) an electroconductive amount of 20-99% by weight of a metalo-phthalocyanine or an alkyl ester thereof in which each of two benzene nuclei of the four benzene nuclei condensed in the phthalocyanine ring has only one carboxyl or alkoxy carbonyl radical attached thereto, and (b) an organic polymer.
Claim 3
Dependent Claim
21 words
The composition according to claim 1 wherein the radical attached to each of the substituted benzene nuclei is a carboxyl radical.
Claim 4
Dependent Claim
22 words
The composition according to claim 1 wherein the radical attached to each of the substituted benzene nuclei is an alkoxy carbonyl radical.
Claim 5
Dependent Claim
27 words
The composition according to claim 1 wherein the carboxyl or alkoxy carbonyl radical is attached to each of the benzene nuclei at their respective 3- or 4-positions.
Claim 6
Dependent Claim
50 words
The composition according to claim 4 wherein the carboxyl or alkoxy carbonyl radicals are present at positions selected from the group consisting of 3- and 3'-positions, 3- and 4'-positions, 4- and 3'-positions, 4- and 4'-positions, 3- and 3"-positions, 3- and 4"-positions, 4- and 3"-positions, 4- and 4"-positions, and combinations thereof.
Claim 7
Dependent Claim
24 words
The composition according to claim 1 wherein the alkyl of the alkoxy carbonyl radical is unsubstituted one containing 1 to about 30 carbon atoms.
Claim 8
Dependent Claim
19 words
The composition according to claim 1 wherein the central metal atom is selected from iron, copper, cobalt, and nickel.
Claim 9
Dependent Claim
28 words
The composition according to claim 1 wherein the polymer is selected from vinyl resins, vinylidene resins, polyurethanes, polyesters, polyamides, cellulose derivatives, epoxy resins, phenolic resins, polyethylene, and polypropylene.
Claim 10
Dependent Claim
23 words
The composition according to claim 1 wherein the polymer is present in an amount of 1 to 80% by weight of the composition.
Claim 11
Dependent Claim
13 words
The composition according to claim 1 which is further doped with a dopant.
Claim 12
Dependent Claim
