Patent ID: 7686877

Claim:
Pigmented tinting concentrates comprising a) stabilized pigments; b) humectant compounds obtained by effecting a Diels Alder reaction at a temperature of 150-260° C. between a polyunsaturated compound and a co-reactant having the formula R 1 XOC—CH═CH—COXR 2 or CH 2 ═CH—COXR 3 or CH 2 CH(CH 3 )—COXR 3 wherein X is oxygen or —NH— and wherein at least one of R 1 and R 2 is a polyether moiety and any other of R 1 and R 2 is a polyether moiety or hydrogen and R 3 is a polyether moiety wherein the humectant compound is a compound of the formula I wherein a, b and c are each independently 0 or 1; with the proviso that a is 1 when b and c are 0; Y is —CH 2 —, when a, b and c are 1; and Y is C 1 -C 20 alkyl or a polyether moiety when a is 1 and b and c are zero; R 4 is X is oxygen or —NH—; R 5 and R 6 are hydrogen or R 4 or polyunsaturated fatty acid moieties; at least one of R 1 and R 2 is a polyether moiety and any other of R 1 and R 2 is a polyether moiety or hydrogen; R 3 is a polyether moiety, R 7 is hydrogen or methyl; W —(CH 2 )— or —(CH 2 ) p′ —CO—(CH 2 ) q —; n is 0 to 20; m is (2n-2) to 2n; p is 1 to 20; p′ is 1 to 20; q is 1 to 20.
