Heterocyclic disperse dye compounds, their production and their use for dyeing or printing of hydrophobic fibers

Claim 1

A heterocyclic compound of the following formula (I), wherein A 1 , A 2 , A3 and A4 are each independently a hydrogen atom, a halogen atom or an unsubstituted or substituted alkyl, alkoxy or alkenyl group, X 1 is -O-or in which R 2 is a hydrogen atom or an unsubstituted or substituted alkyl, alkenyl, cycloalkyl, aryl or aralkyl group and R 2 may link to A3 or A4 to form a heterocyclic ring, R 1 is a methylene group or a straight or branched C 2 - 6 alkylene group unsubstituted or substituted by a hydroxy group, a C 1-4 alkoxy group or a C 1 - 4 alkylcarbonyloxy group, X 2 is a direct linkage or a divalent group of -O-, -S-, -SO-, -S0 2 -, in which R 3 is a hydrogen atom or a C 1 - 4 alkyl group, in which R 3 is as defined above, T and u are each independently a hydrogen atom or a C 1 - 4 alkyl group, ℓ is O or an integer of 1 to 3, Q is an unsubstituted or substituted 5-, 6- or 7-membered saturated or unsaturated heterocyclic residue, Y is a hydrogen atom, a C 1 - 4 alkyl group, a C 1 - 4 alkoxy group, a group of the formula (i), in which R 1 , X 2 , T, u, Q and tare as defined above, and X 3 is in which R 4 is a hydrogen atom or an unsubstituted or substituted alkyl, alkenyl, cycloalkyl, aryl or aralkyl group and R 4 may link to A 1 or A 2 to form a hetrocyclic ring, provided that the group of the formula (i) as Y is the same as or different from the group of the formula(i) appended to Xi, a group of the formula (ii), in which L 1 and L 2 are each independently a hydrogen atom or an unsubstituted or substituted alkyl, alkenyl, cycloalkyl, aryl or aralkyl group and one of L 1 and L 2 may link to A 1 or A 2 to form heterocyclic ring, or a group of the formula (iii), in which L 3 and L 4 are each independently an alkylene group, an alkenylene group or a C 1-4 alkylcarbonyl group, or a group of the formula (iv) in which L 3 and L 4 are as defined above, and Y may link to A 1 or A 2 to form -OCH 2 0-, with a proviso that when X is -O-, Y is (ii) in which L 1 and L 2 are as defined above, (iii) in which L 3 and L 4 are as defined above, (iV) in which L 3 and L 4 are as defined above, or (i) in which X 3 , R i , X 2 , T, u, ℓ and Q are as defined above.
