Abstract
A composition contains a compound of formula (1), and a polymerizable liquid crystal compound or a liquid crystalline polymer compound. n represents 1 or 2; Ar1, Ar2, and Ar3 each represent a 1,4-phenylene group or a divalent sulfur-containing aromatic heterocyclic group; At least one of Ar1 and Ar2 has a fluorine atom; R1 represents a single bond or a group selected from —OC(═O)—, —C(═O)O—, —C≡C—, —CH═CH—, —CH═N—, —N═N—, and —N═CH—; R2 represents an alkylamino group or an alkoxy group; R3 represents a group selected from an alkanediyl group, an alkanediyloxy group, an alkanediyloxycarbonyl group, and an alkanediylcarbonyloxy group; and R4 represents a polymerizable group or a hydrogen atom.

Claims8
A composition comprising:
- a compound represented by the following formula (1) and having a maximum absorption wavelength in a range of 420 nm or more and 520 nm or less;
- and at least one of a polymerizable liquid crystal compound and a liquid crystalline polymer compound:
- R4—R3—Ar1—(—R1—Ar2—)n—N═N—Ar3—R2 (1)
- wherein n is an integer of 1 or 2;
- Arl, Ar2, and Ar3 each independently represent a 1,4-phenylene group optionally having a substituent or a divalent sulfur-containing aromatic heterocyclic group optionally having a substituent, and at least one of Ar1 and Ar2 has 1 or 2 fluorine atoms as a substituent;
- wherein if Ar2 represents a 1,4-phenylene group optionally having a substituent,
- R1 represents a single bond or at least one group selected from the group consisting of —OC(═O)—, —C(═O)O—, —CH═CH—, —CH═N—, —N═N—, and —N═CH—;
- wherein if Ar2 represents a divalent sulfur containing aromatic heterocyclic group optionally having a substituent,
- R1 represents a single bond or at least one group selected from the group consisting of —OC(═O)—, —C(═O)O—, —CH═CH—, —CH═N—, and —N═CH—;
- R2 represents an alkylamino group optionally having a polymerizable group or an alkoxy group optionally having a polymerizable group;
- wherein if R2 represents an alkoxy group optionally having a polymerizable group,
- at least one of Ar1, Ar2 and Ar3 represents a divalent sulfur-containing aromatic heterocyclic group optionally having a substituent;
- R3 represents at least one group selected from the group consisting of an alkanediyl group having 4 to 20 carbon atoms, an alkanediyloxy group having 2 to 20 carbon atoms, an alkanediyloxycarbonyl group having 2 to 20 carbon atoms, and an alkanediylcarbonyloxy group having 2 to 20 carbon atoms;
- R4 represents a polymerizable group or a hydrogen atom;
- and
- when n is 2, two R1s may be the same as or different from each other, and two Ar2s may be the same as or different from each other.
