The haze of the medium / high refractive index layer is preferably 5% or less, more preferably 3% or less, and most preferably 1% or less. The medium / high refractive index layer can be formed by using a polymer binder having a relatively high refractive index. Polymers with high refractive index include polystyrene, styrene copolymer, styrene-butadiene copolymer, polyvinyl chloride, polycarbonate, polyamide, melamine resin, phenol resin, epoxy resin, cyclic (alicyclic or aromatic) isocyanate and polyol. Examples thereof include polyurethane obtained by the above reaction. Polymers having other cyclic (aromatic, heterocyclic, alicyclic) groups and polymers having a halogen atom other than fluorine as a substituent also have a high refractive index. A polymer formed by a polymerization reaction of a monomer in which a double bond is introduced to enable radical curing may be used.

Inorganic fine particles may be dispersed in the polymer binder in order to obtain a higher refractive index. The refractive index of the inorganic fine particles is preferably 1.80 to 2.80. The inorganic fine particles are preferably formed from metal oxides or sulfides. Examples of the oxide or sulfide of the metal include titanium oxide (for example, rutile, mixed crystal of rutile / anatase, anatase, amorphous structure), tin oxide, indium oxide, zinc oxide, zirconium oxide, zinc sulfide and the like. Of these, titanium oxide, tin oxide and indium oxide are particularly preferable. The inorganic fine particles are mainly composed of oxides or sulfides of these metals, and may further contain other elements. The principal component means a component having the highest content (mass%) among the components constituting the particles. Examples of other elements include Ti, Zr, Sn, Sb, Cu, Fe, Mn, Pb, Cd, As, Cr, Hg, Zn, Al, Mg, Si, P, S and the like. Inorganic materials that are film-forming and can be dispersed in solvents or are liquid in their own right, such as alkoxides of various elements, salts of organic acids, coordination compounds bound to coordination compounds (eg chelate compounds), active inorganics. A medium / high refractive index layer can also be formed by using a polymer.

An anti-glare function (a function of scattering incident light on the surface to prevent the scenery around the film from being transferred to the film surface) can be imparted to the surface of the antireflection layer. For example, it has an anti-glare function by forming fine irregularities on the surface of a transparent film to form an antireflection layer on the surface, or by forming irregularities on the surface by embossing roll after forming the antireflection layer. An antireflection layer can be obtained. Anti-reflective layers with anti-glare function generally have a haze of 3-30%.

The hard coat layer that can be provided in the optical filter of the present invention has a hardness higher than the hardness of the transparent support. The hard coat layer preferably contains a crosslinked polymer. The hard coat layer can be formed by using an acrylic-based, urethane-based, epoxy-based polymer, oligomer, monomer (for example, ultraviolet curable resin) or the like. A hard coat layer can also be formed from a silica-based material.

The surface of the antireflection layer (low refractive index layer) may form a lubricating layer. The lubricating layer has a function of imparting slipperiness to the surface of the low refractive index layer and improving scratch resistance. The lubricating layer can be formed by using a polyorganosiloxane (for example, silicon oil), a natural wax, a petroleum wax, a higher fatty acid metal salt, a fluorine-based lubricant or a derivative thereof. The thickness of the lubricating layer is preferably 2 to 20 nm.

When the above polymer binder is used, an organic solvent can be used at the same time, and various known solvents can be appropriately used as the organic solvent without particular limitation. For example, an alcohol such as isopropanol can be used as appropriate. Classes: Ether alcohols such as methyl cellosolve, ethyl cellosolve, butyl cellosolve, butyl diglycol; ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, diacetone alcohol, esters such as ethyl acetate, butyl acetate, methoxyethyl acetate, etc. Acrylic acid esters such as ethyl acrylate and butyl acrylate, fluoroalcohols such as 2,2,3,3-tetrafluoropropanol; hydrocarbons such as hexane, benzene, toluene and xylene; methylene dichloride, dichloroethane , Chlorinated hydrocarbons such as chloroform and the like. These organic solvents can be used alone or in combination.
Is preferable.

Further, the undercoat layer, the antireflection layer, the hard coat layer, the lubricating layer, the filter layer and the like can be formed by a general coating method. Examples of the coating method include a dip coating method, an air knife coating method, a curtain coating method, a roller coating method, a wire bar coating method, a gravure coating method, and an extrusion coating method using a hopper (described in US Pat. No. 2,681294). Can be mentioned. Two or more layers may be formed by simultaneous coating. Regarding the simultaneous coating method, the specifications of US Pat. No. 2761791, US Pat.

When the methylene group in the alkyl group, arylalkyl group or arylalkenyl group represented by R ²³ and R ²⁴ is replaced by an unsaturated bond, -O- or -S-, under the condition that the oxygen atoms are not adjacent to each other. There is also
R ²³ is, in some cases form a ring with the adjacent ^{R 23} to each other,
e represents a number from 0 to 4, f represents a number from 0 to 8, g represents a number from 0 to 4, h represents a number from 0 to 4, and the sum of the numbers of g and h is 2 to 2. 4, where * means that the * portion is attached to an adjacent group. ) A composition containing the merocyanine compound according to any one of claims 1 to 10 .
