Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
106 words
An improved process for the synthesis and concomitant conditioning of an organic pigment selected from the group consisting of the diketopyrrolopyrrole, perylene, quinacridone, phthalocyanine, perinone, quinophthalone, isoindolinone, isoindoline, dioxazine, anthraquinone, thioindigo, methine, azomethine and azo pigments and the metal salts or complexes of the azomethine, methine, azo and phthalocyanine pigments, wherein the improvement comprises carrying out the synthesis and concomitant conditioning of said pigment in the presence of a tricyclic alcohol which is 8(9)-hydroxytricyclo[5.2.1.0 2 ,6 ]dec-3-ene or which has the formula ##STR3## wherein n is 0 or 1, and X is hydrogen or the --CH 2 OH group; or a mixture of said tricyclic alcohols.
Claim 2
Dependent Claim
106 words
An improved process for the synthesis and concomitant conditioning of an organic pigment selected from the group consisting of the diketopyrrolopyrrole, perylene, quinacridone, phthalocyanine, perinone, quinophthalone, isoindolinone, isoindoline, dioxazine, anthraquinone, thioindigo, methine, azomethine and azo pigments and the metal salts or complexes of the azomethine, methine, azo and phthalocyanine pigments, wherein the improvement comprises carrying out the synthesis and concomitant conditioning of said pigment in the presence of a tricyclic alcohol which is 8(9)-hydroxytricyclo[5.2.1.0 2 ,6 ]dec-3-ene or which has the formula ##STR3## wherein n is 0 or 1, and X is hydrogen or the --CH 2 OH group; or a mixture of said tricyclic alcohols.
Claim 3
Dependent Claim
28 words
A process according to claim 1 wherein the organic pigment is selected from the group consisting of the anthraquinone, perylene, perinone, quinacridone, dioxazine, metal phthalocyanine and azo pigments.
Claim 4
Dependent Claim
18 words
A process according to claim 1, wherein the organic pigment is a metal phthalocyanine or an azo pigment.
Claim 5
Dependent Claim
28 words
A process according to claim 1, wherein the conditioning takes the form of a grinding procedure in the presence of small amounts of at least one tricyclic alcohol.
Claim 6
Dependent Claim
26 words
A process according to claim 4, wherein the amount of tricyclic alcohol is from 0.05 to 25% by weight, based on the pigment to be ground.
Claim 7
Dependent Claim

Claim 8
Dependent Claim
15 words
A process according to claim 6, wherein the tricyclodecane alcohol is 8(9)-hydroxymethyltricyclo[5.2.1.0 2 ,6 ]decane.
Claim 9
Dependent Claim
95 words
A process for the conditioning of an organic pigment selected from the group consisting of the diketopyrrolopyrrole, perylene, quinacridone, phthalocyanine, perinone, quinophthalone, isoindolinone, isoindoline, dioxazine, anthraquinone, thioindigo, methine, azomethine and azo pigments and the metal salts or complexes of the azomethine, methine, azo and phthalocyanine pigments which comprises conditioning the preformed crude pigment in the presence of a tricyclic alcohol which is 8(9)-hydroxytricyclo[5.2.1.0 2 ,6 ]dec-3-ene or which has the formula ##STR4## wherein n is 0 to 1, and X is hydrogen or the --CH 2 OH group; or a mixture of said tricyclic alcohols.
Claim 10
Dependent Claim
95 words
A process for the conditioning of an organic pigment selected from the group consisting of the diketopyrrolopyrrole, perylene, quinacridone, phthalocyanine, perinone, quinophthalone, isoindolinone, isoindoline, dioxazine, anthraquinone, thioindigo, methine, azomethine and azo pigments and the metal salts or complexes of the azomethine, methine, azo and phthalocyanine pigments which comprises conditioning the preformed crude pigment in the presence of a tricyclic alcohol which is 8(9)-hydroxytricyclo[5.2.1.0 2 ,6 ]dec-3-ene or which has the formula ##STR4## wherein n is 0 to 1, and X is hydrogen or the --CH 2 OH group; or a mixture of said tricyclic alcohols.
Claim 11
Dependent Claim
24 words
