Description

[Technical Field]

[0001] The present invention provides a polymerizable liquid crystal composition, a cured liquid crystal film which is a cured product of the polymerizable liquid crystal composition, a method for producing the cured liquid crystal film, and the use of the liquid crystal film in the manufacture of an optical apparatus or electro-optical apparatus.

[0002] There is a demand for anisotropic liquid crystal films that exhibit negative optical phase difference dispersion. For example, a quarter-wavelength film made from a negative dispersion birefringent material would be nearly colorless. Devices such as reflective LCDs that utilize such a quarter-wavelength film would have an uncolored dark state.

[0003] WO No. 2021 / 037774 relates to a composition for an optical film comprising at least two anisotropic liquid crystal compounds. This optical film exhibits an inverse phase difference pattern of polarization over a broad wavelength band.

[0004] A cured liquid crystal film formed from a liquid crystal composition containing a polymerizable liquid crystal (LCP) compound is typically formed by orienting the polymerizable liquid crystal compound, which is in a liquid crystal state, on an orientation substrate to obtain a polymerizable liquid crystal layer in which the molecules have a predetermined orientation, and then polymerizing the liquid crystal to form a network in which the orientation of the liquid crystal is fixed. The film in which the orientation of the liquid crystal is fixed can be removed from the orientation substrate and transferred to another substrate, for example, by using an adhesive.

[0005] In most cases, polymerization is induced by irradiation with light such as ultraviolet light, and photopolymerization initiators are used as polymerization initiators.

[0006] WO No. 2021 / 175855 discloses α-oxoxime ester compounds based on carbazole derivatives having specific substituents useful as photopolymerization initiators.

[0007] Liquid crystal polymer (LCP) materials are stable at room temperature, but may degrade when exposed to high temperatures. In particular, optical properties, such as phase difference, decrease, which leads to a deterioration in the performance of LC films over time.

[0008] The cause of this degradation is not fully understood. However, it may be at least partially due to low polymerization rates and high free radical content. Polymerizable liquid crystal compounds, which may exhibit inverse wavelength dispersion, generally have maximum absorption in the wavelength range of active energy rays, such as ultraviolet light, which cleaves polymerization initiators. Some of the active energy rays irradiated onto polymerizable liquid crystal compounds are absorbed by the polymerizable liquid crystal compound, which tends to hinder the cleavage of photopolymerization initiators, making it difficult to achieve high polymerization rates.

[0009] To improve the polymerization rate of such polymerizable liquid crystal compounds, it is necessary to irradiate them with high-intensity active energy rays, taking into account the absorption of active energy rays by the polymerizable liquid crystal compounds. As a result, structural destruction of the polymerizable liquid crystal compounds and the resulting orientation defects are more likely to occur, making it difficult to impart high optical properties to the resulting liquid crystal film.

[0010] Therefore, there is a demand for LCP compositions for producing oriented polymer films that exhibit desirable high-temperature stability.

[0042] The polymerizable liquid crystal composition includes a polymerizable liquid crystal compound that, when in an oriented state, can exhibit reverse wavelength-dispersive birefringence.

[0043] A useful parameter for evaluating the inverse wavelength-dispersive birefringence of a material is Re, which indicates the phase difference of the material at a wavelength of 450 nm. 450 The value indicates the phase difference of the material at a wavelength of 550 nm. 550 The value and the phase difference of the material at a wavelength of 650 nm are shown by Re 650 This is a value. The phase difference Re (nm) of a material is defined as the product of the birefringence Δn at a given wavelength and the layer thickness d (nm).

[0044] In a material having birefringence with inverse wavelength dispersion, Re450 / Re 550 The value is less than 1.0, Re 650 / Re 550 The value of is greater than 1.0. This means that the magnitude of the birefringence Δn increases as the wavelength λ increases.

[0077] To reduce film thickness variations when forming thin films, such as optical anisotropes or optical films, it is preferable to add a leveling agent to the polymerizable liquid crystal composition. Suitable leveling agents include silicone-based agents, such as modified polydimethylsiloxane (PDMS), acrylate-based agents, such as polyacrylate, fluorocarbon-based agents, and hydrocarbon-based leveling agents, particularly polyacrylate, such as Tego® Flow available from Evonik.

[0078] The polymerizable liquid crystal composition preferably contains a leveling agent in an amount of 0.0075 to 2.0 wt%, preferably 0.02 to 0.5 wt%, relative to the total weight of the polymerizable liquid crystal composition.

[0079] Further polymerizable compounds other than polymerizable liquid crystal compound (i) can be added to the polymerizable liquid crystal composition to improve the mechanical strength of the liquid crystal film, or to improve its chemical resistance, or both. These compounds are preferably mesogenic. Preferably, the further polymerizable compounds are selected from reactive mesogens, and most preferably from monoreactive and direactive mesogens.

[0080] The term "mesogenic" refers to a compound containing one or more calamistic (rod-shaped or plate-shaped / lath-shaped) or discotic (disc-shaped) mesogenic groups. The term "mesogenic group" refers to a group that has the ability to induce liquid crystal (LC) phase behavior. Compounds containing mesogenic groups do not necessarily have to exhibit liquid crystal phase behavior on their own. Furthermore, compounds containing mesogenic groups may exhibit liquid crystal phase behavior only in mixtures with other compounds, or only when the mesogenic compound, material, or mixture thereof is polymerized.

[0081] A calamistic mesogenic group typically comprises a mesogenic core consisting of one or more aromatic or non-aromatic cyclic groups linked to each other directly or via a crosslinking group, optionally including terminal groups attached to the ends of the mesogenic core, and optionally including one or more side groups attached to the long sides of the mesogenic core. Here, these terminal and side groups can be selected from carbyl groups or hydrocarbyl groups, polar groups such as halogens, nitro, hydroxy, etc., or polymerizable groups. The term "reactive mesogen (RM)" means a polymerizable mesogenic compound. A polymerizable compound having one polymerizable group is also called a "monoreactive" compound, a compound having two polymerizable groups is also called a "direactive" compound, and a compound having three or more polymerizable groups is also called a "polyreactive" compound. Examples of such compounds are well known to those skilled in the art and are described, for example, in WO 2018 / 099883. Further examples of polymerizable compounds include [3-methyl-4-[4-(6-propa-2-enoyloxyhexoxy)benzoyl]oxyphenyl]4-(6-propa-2-enoyloxyhexoxy)benzoate (FPC-1), as shown below. [ka]

[0082] Furthermore, the present invention relates to a liquid crystal film, which is a cured product of a polymerizable liquid crystal composition.

[0083] The present invention also relates to a method for manufacturing a liquid crystal film, comprising: oriented a polymerizable liquid crystal compound to obtain a polymerizable liquid crystal layer having a predetermined orientation; polymerizing the polymerizable liquid crystal compound to form a network in which the orientation of the liquid crystal is fixed; and laminating the liquid crystal film onto a pressure-sensitive adhesive coated on a substrate.

[0084] The orientation of a polymerizable liquid crystal composition can be achieved, for example, by coating an organic solution of the polymerizable liquid crystal composition onto an orientation substrate equipped with an orientation layer. The orientation layer typically contains a photo-orienting material that can induce anisotropy by exposure to orientation light. The induced anisotropy provides suitable orientation capabilities for the polymerizable liquid crystal composition of the present invention. The term "orientation direction" refers to the direction to which the polymerizable liquid crystal composition is preferably oriented. That is, the orientation direction is the direction in which the liquid crystal molecules are oriented.

[0085] Photo-oriented materials contain photo-oriented portions that exhibit a preferred orientation when exposed to oriented light, thereby generating anisotropic properties. Such photo-oriented portions preferably have anisotropic absorption properties. Typically, such portions exhibit absorption in the wavelength range of 230 to 500 nm. Preferably, the photo-oriented portions exhibit absorption of light in the wavelength range of 300 to 450 nm, with portions exhibiting absorption in the wavelength range of 310 to 380 nm being more preferable.

[0086] Preferably, the photo-oriented portion has carbon-carbon, carbon-nitrogen, or nitrogen-nitrogen double bonds.

[0087] For example, the photo-orienting moiety may be a substituted or unsubstituted azo dye, such as anthraquinone, coumarin, melisyanin, 2-phenylazothiazole, 2-phenylazobenzthiazole, stilbene, cyanostilbene, fluorostilbene, cinnamonitrile, chalcone, cinnamate, cyanocinnamate, stilbazolium, 1,4-bis(2-phenylethylenel)benzene, 4,4'-bis(arylazo)stilbene, perylene, 4,8-diamino-1,5-naphthoquinone dye, aryloxycarboxylic acid derivatives, aryl esters, N-arylamides, polyimides, and diarylketones having a ketone moiety or ketone derivative conjugated to two aromatic rings, such as substituted benzophenone, benzophenone imine, phenylhydrazone, and semicarbazone.

[0088] The preparation of the anisotropic absorbent materials listed above is well known, as shown, for example, in US No. 4,565,424 (Hoffman et al.), No. 4,401,369 (Jones et al.), No. 4,122,027 (Cole Jr. et al.), No. 4,667,020 (Etzbach et al.), and No. 5,389,285 (Shannon et al.).

[0089] Preferably, the photo-oriented portion includes aryl azo, poly(aryl azo), stilbene, cyanostilbene, cinnamate, or chalcone.

[0090] Photo-orienting materials may be monomers, oligomers, or polymers. The photo-orienting moiety may be covalently bonded, for example, within the main chain or side chains of a polymer or oligomer, or it may be part of a non-polymerizable monomer or other compound. Furthermore, photo-orienting materials may be copolymers containing different types of photo-orienting moieties, or copolymers containing side chains with and without photo-orienting moieties.

[0091] Polymers include, for example, polyacrylates, polymethacrylates, polyimides, polyurethanes, polyamic acids, polymaleimides, poly-2-chloroacrylates, poly-2-phenylacrylates; unsubstituted or C1-C6 alkyl-substituted polyacrylamides, polymethacrylamides, poly-2-chloroacrylamides, poly-2-phenylacrylamides, polyethers, polyvinyl ethers, polyesters, polyvinyl esters, polystyrene derivatives, polysiloxanes, linear or branched alkyl esters of polyacrylic acid or polymethacrylic acid; polyphenoxyalkyl acrylates, polyphenoxyalkyl methacrylates, polyphenylalkyl methacrylates having alkyl residues of 1 to 20 carbon atoms; polyacrylonitriles, polymethacrylonitriles, cycloolefin polymers, polystyrene, poly-4-methylstyrene, or mixtures thereof.

[0092] Furthermore, photo-oriented substances may also contain photosensitizers, such as ketocoumarins and benzophenones.

[0093] Furthermore, preferred photo-oriented monomers, oligomers, or polymers are described in US Patent Nos. 5,539,074, 6,201,087, 6,107,427, 6,632,909, and 7,959,990.

[0094] After coating, the organic solvent is removed to obtain a solvent-free liquid crystal layer in which the molecules have a predetermined orientation.

[0095] Furthermore, the orientation of the polymerizable liquid crystal composition can also be achieved by other known means for aligning liquid crystals, such as coating the polymerizable liquid crystal composition onto a substrate that has been pre-treated by friction technology.

[0096] Polymerizable liquid crystal compounds are polymerized to form a network in which the orientation of the liquid crystals is fixed.

[0097] The steps of polymerizing the polymerizable liquid crystal composition and exposing it to alignment light can be performed in any order. Polymerization can be started before or after exposure to alignment light, or polymerization and exposure can be performed simultaneously.

[0098] Furthermore, the liquid crystal composition can be coated onto a support, and the support may have an orientation surface. An orientation surface means that the surface has the ability to orient the liquid crystal. The support may already provide orientation without further processing. For example, when a plastic substrate is used as a support, the plastic substrate may have orientation on its surface by a manufacturing method such as extrusion molding or stretching of the substrate. It is also possible to generate orientation ability by brushing or friction-treating the support or by transferring a directional microstructure.

[0099] The support may be rigid or flexible and may have any form or shape. In principle, the support can be made of any material. Preferably, the support includes plastic, glass or metal, or is a silicon wafer. If the support is flexible, it is preferably a plastic or metal foil. Preferably, the surface of the support is flat. In some applications, the support may include a topographic surface structure, such as a microstructure, such as microlenses or microprisms, or a structure exhibiting abrupt changes in shape, such as a rectangular structure. Preferably, the support is transparent. The support may also be subjected to processing before being coated with the polymerizable liquid crystal composition of the present invention.

[0100] The support can be moved during the deposition of the polymerizable liquid crystal composition. For example, a layer of polymerizable liquid crystal composition can be manufactured in a continuous roll-to-roll process by depositing the composition on a movable, flexible foil, preferably made of plastic or metal. The resulting film can then be wound onto a roll together with the support foil, or the film can be peeled from the support and then wound up as a self-supporting film without a support.

[0101] The support may have additional layers, such as an organic layer, a dielectric layer, or a metal layer. These layers can have various functions. For example, the organic layer can be coated as a primer layer. The primer layer improves the compatibility between the coated material and the support. The metal layer may be used as an electrode or as a reflector, for example, when used in electro-optical devices, such as displays. The support may also be an optical element or device with a specific function, such as a substrate for an LCD. A substrate for an LCD may include, for example, a thin-film transistor, an electrode, or a color filter. In another example, the support is a device containing an OLED layer structure. The support may also be a polarizer, such as a polarizing film or sheet polarizer, or a reflective polarizer, such as the commercially available Vikuity® DBEF film.

[0102] Polymerizable liquid crystal compositions can be coated onto substrates by general coating and printing methods known in the art. Coating methods include, for example, spin coating, blade coating, knife coating, reverse roll coating, transfer roll coating, gravure roll coating, kiss roll coating, cast coating, spray coating, slot orifice coating, calender coating, electrodeposition coating, dip coating, or die coating. Printing methods include letterpress printing, such as flexographic printing, inkjet printing, intaglio printing, such as direct gravure printing or offset gravure printing, lithographic printing, such as offset printing or stencil printing, or screen printing. A preferred printing method is inkjet printing.

[0103] Liquid crystal films exhibit birefringence with reverse wavelength dispersion.

[0104] The inverse wavelength dispersion of a material is expressed by the phase difference of the material at a wavelength of 450 nm. 450 The value indicates the phase difference of the material at a wavelength of 550 nm. 550 The value and the phase difference of the material at a wavelength of 650 nm are shown. 650 It can be evaluated by its value. In materials with birefringence of inverse wavelength dispersion, Re 450 / Re 550 The value is less than 1.0, Re 650 / Re 550 The value of is greater than 1.0. This means that the magnitude of birefringence (Δn) increases as the wavelength λ increases.

[0105] Furthermore, the present invention provides the use of the liquid crystal film in the manufacture of colorless phase difference elements in optical devices or electro-optical devices, such as optical compensators for improving the viewing angle of liquid crystal displays or for anti-reflective applications in OLEDs.

[0106] The present invention will be described in more detail by the accompanying drawings and the embodiments described below.

[0109] method Quality of orientation The quality of liquid crystal alignment in the film was confirmed by placing the film between two cross-polarizing plates and adjusting the conditions to obtain a dark state. If the dark state shows no defects and the liquid crystals are sufficiently aligned, the alignment quality is defined as very good. If the dark state has light leakage due to the heterogeneous alignment of the liquid crystals, the alignment quality is defined as good. If the dark state has light leakage accompanied by some crystallized regions, the alignment quality is defined as moderate. If there is no dark state and the liquid crystals are not aligned, the alignment quality is defined as poor.

[0110] Thermal reliability Films of compositions 1 to X described below were laminated onto a pressure-sensitive adhesive PSA OC8171 (3M) coated on a glass substrate. Then, the TAC substrate was peeled off. Next, the entire glass / PSA / polymer film laminate was subjected to a thermal reliability experiment. The film was stressed at 85°C for a maximum of 200 hours. The phase difference before and after thermal stress was measured using an Axoscan ellipsometer. The % reliability to the heat treatment was quantified by dividing the difference in phase difference at 550 nm ΔRe before and after heating at 85°C by the phase difference before stress.

[0111] The results of the thermal reliability evaluation are summarized in Table 1.

[0112] Preparation of the orientation layer A TAC substrate of 80 μm (FT TD80ULM, manufactured by Fujifilm) was spin-coated with a photo-alignment composition (LPP polymer in cyclopentanone (3% solids content) as described in WO 2012 / 085048). The coated substrate was dried at 80°C for 30 seconds. The thickness of the resulting polymer layer was approximately 100 nm. Subsequently, the polymer layer was exposed to parallel and linearly polarized UV (LPUV) light (280-320 nm) at 250 mJ / cm². 2 The light was exposed to the light. The polarization plane was 0° with respect to the reference edge on the substrate.
