Abstract:
1. A color correction material comprising: at least one cyanine compound composed of a cyanine cation represented by general formula (I) below and a q-valent anion represented by pAn q- wherein q is an integer of 1 or 2, and p represents a coefficient for keeping the electric charge neutral; and at least one layered clay mineral, wherein the layered clay mineral is an oleophilic smectite: wherein: ring A represents a benzene ring or a naphthalene ring; the hydrogen atom in the ring A may be substituted by an alkyl group having 1 to 10 carbon atoms, an aryl group having 6 to 20 carbon atoms, an arylalkyl group having 7 to 20 carbon atoms, a nitro group, a cyano group, or a halogen atom; X represents a sulfur atom; R R Y the methylene group in the alkyl group, the aryl group, and the arylalkyl group, which are the groups that may substitute the hydrogen atom in the ring A or the groups that may be represented by R Z represents a hydrogen atom; in the above general formula (II): the bond between G and T is a double bond, a conjugated double bond, or a triple bond; G represents a carbon atom; T represents a carbon atom, an oxygen atom, or a nitrogen atom if T is an oxygen atom, then y and z are 0; if T is a nitrogen atom, then y+z is 0 or 1; w represents a number from 0 to 4; x, y, and z each represent 0 or 1; R in the above general formula (II′) : the bond between G′ and T′ is a double bond or a conjugated double bond; G′ represents a carbon atom; T′ represents a carbon atom or a nitrogen atom; w′ represents a number from 0 to 4; R the ring containing G′ and T′ represents a 5-membered ring that may contain a hetero atom, a 6-membered ring that may contain a hetero atom, a naphthalene ring, a quinoline ring, an isoquinoline ring, an anthracene ring, or an anthraquinone ring; and the ring containing G′ and T′ may be substituted by a halogen atom, a hydroxyl group, a nitro group, a cyano group, an alkyl group having 1 to 4 carbon atoms, or an alkoxy group having 1 to 4 carbon atoms; wherein: R a , R b , R c , R d , R e , R f , R g , R h , and R i each independently represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms; the methylene group in the alkyl group may be interrupted by —O— or —CO—; Q represents a direct bond or an optionally substituted alkylene group having 1 to 8 carbon atoms; the methylene group in the alkylene group may be replaced by —O—, —S—, —CO—, —COO—, —OCO—, —SO M represents Fe, Co, Ni, Ti, Cu, Zn, Zr, Cr, Mo, Os, Mn, Ru, Sn, Pd, Rh, Pt, or Ir.
