[Embodiment] '[Form of the invention] Polyester film) ... Ben Ming: The polyester resin constituting the substrate can be made from poly-p-formic acid ethyl vinegar, polybutylene terephthalate, polyethylene-2,6•naphthoic acid, polyaluminum Terephthalic acid, and a diol component such as diethylene glycol, neopentyl glycol, polyphenol diol, or adipic acid, sebacic acid, benzoic acid, isophthalic acid as a copolymerization component A poly-resin resin obtained by copolymerizing a bismuth component such as diterpenic acid or 2,6-naphthalene dinon or the like. The polyacetal resin suitable for use in the present invention is mainly a polyparaphenylene phthalate , poly-p-benzoic acid propylene diacetate, poly-terephthalic acid di-branched, poly---------------------------- The balance between the physical properties and the cost of the resin is best known as the phthalic acid. Moreover, the polyester film can be improved in chemical resistance, heat resistance, mechanical strength and the like by biaxial stretching. Further, the biaxially stretched polyester film may be a single layer or a plurality of layers. Further, as long as it is within the range of the effect of the invention, it may be in the case of (4) The purpose of the tree contains various additives. Additives such as · anti-oxidants, light stabilizers, anti-coagulants, organic wetting agents, anti-electrostatic agents, UV absorbers, surfactants, etc. 8/48 201233550 Also, in order to improve There are cases where the film has inert properties such as slip properties, windability, and anti-adhesive properties, or abrasion resistance such as abrasion resistance and scratch resistance. However, since the film of the present invention is used as a base film of an optical member, it is required to maintain high transparency and excellent workability. Specifically, in the case of using a base film as an optical member, it is preferable that the (four) visible poly film has a total light transmittance of 85% or more, more preferably 87% or more, still more preferably 88% or more. , especially good is 89% or more, especially good is more than 9〇%. The amount of inert particles in the film of the material (4) should be as small as possible. Therefore, a preferred embodiment is a multilayer structure containing particles only in the surface layer, or substantially no particles in the film, and only fine particles are contained in the coating layer. The consideration of granule property does not contain inertness in the case of poly (four), but it is also preferable to make inorganic and/or concave and convex. In the water-based coating liquid, the granules are formed on the surface of the coating layer, and the granules are formed on the surface of the coating layer: "There is no inclusion of inert particles in nature" means, for example, in the case of no line, and in the case of When the element of the particle is analyzed in the enthalpy, it is 50 ppm or less, and the content below the detection limit is 2 = 10 ppm or less. The best is added to the wire (4) Φ " Even if the grain or the raw material is not actively produced, There may be contaminated components from foreign substances, contaminants = or attached to the device (coating layer). The easily-adhesive poly(tetra) film of the present invention is important to have a main component of amine 9/48 201233550 $ formic acid resin, and A coating layer formed of a blocked isocyanate having a blocking temperature of _ or less and a stagnation point of the block agent of c or more. Here, the "main component" means 50% of the total solid content contained in the coating layer. The mass% or more, more preferably 7 () by mass or more. ° As described in the above-mentioned patent document, it is preferable to use a soft urethane-based resin to improve the adhesion of the coating layer, and it is more preferable to introduce the cross-linking structure positively in order to impart easy adhesion. Strongly coated 2 Lie literature 5, 6 # proposed the use of isocyanate as cross-linking ^. Narrow:: Specialized cross-linkers' or due to high reactivity, or will be associated with amino citrate trees: ^ tend to generate agglomerates. Therefore, the so-called service life (it is difficult to carry out the coating operation for a long period of time. Therefore, it is possible to read 2 the block agent which can be turned off by heating to form the base. In the case of a different mirror, however, since it is not dissociated = 3, it is required to have a good adhesion (humidity and heat resistance) at t temperature and high humidity, and there is a case where sufficient adhesion cannot be obtained. In the in-depth discussion of the uneven surface of the crepe that can be identified by the mirror treatment, it is known that the micro-coating is caused by the above-mentioned block vision vinegar. The disintegrated sputum agent is volatilized by the high temperature and the convex pinhole is volatilized. At the time of the sputum, a small concave shape is formed on the (four) surface, and the result of the smear is found: by using the carboxylic acid s The block isocyanate-coating layer having a resin and a dissociation temperature of less than a thief and having a block defect of i8 G°c or more provides excellent compatibility, compatibility, and appearance. That is, when the dissociation temperature exceeds the above temperature 10/48 201233550 The dissociation of the blocker due to heating will be insufficient and will not be sufficient The joint structure reduces the adhesion (especially, the heat and humidity). Further, when the boiling point of the block agent is lower than the above temperature, the block agent remaining in the coating layer is volatilized by heating to cause a coating appearance. According to the above aspect, the adhesion between the hard coat layer, the lens layer, and even other optical functional layers under high temperature and high humidity can be improved by the above-described aspect. Further, the constitution of the present invention will be described in detail below. (Amino phthalate resin) The component of the urethane resin of the present invention contains at least a polyol component and a polyisocyanate component, and may further contain a chain extender if necessary. The amine phthalate resin of the present invention A polymer compound obtained by copolymerizing a urethane bond mainly with such a constituent component. Examples of the polyol component include polycarboxylic acids (for example, malonic acid, succinic acid, and Diacids, sebacic acid, fumaric acid, maleic acid, p-dibenzoic acid, isophthalic acid, etc.) or their anhydrides and polyols (eg, B-ray, 2-B Glycol, triethylene glycol, propylene glycol, butanediol , 丨, 3_butanediol, butyl hydrazine, 2,3-butanediol, neopentyl glycol, hexylene hexane, etc.) 2 to the polyester polyols; polyethylene glycol, polypropylene glycol, Polyethylene glycols such as 'tetramethylene sulfonium diols and polyhexamethylene sulfonium (10) diols, polycarbons, polycarbons, hydrocarbons, hydrocarbons, polyhydric alcohols, polyhydric alcohols, etc. =, The hydroxyl carboxylic acid of the present day and the moon is composed of a polyol which is a good one (4) a heat-resistant and excellent hydrolysis-resistant polycarbonate = money. In the hair styling (four), the yellow is prevented. In the case of change, the car is also good for the use of aliphatic polycarbonate polyols. When used as an ingredient in the 11/48 201233550 composition containing a fatty acid-based acid-soluble resin as a urethane resin, it can be used as an optical component. Applicable photo-curable resin for the functional layer is widely used. Based on this point, the coating layer is measured by infrared spectrometry. The absorbance (Ai46〇) near the 146〇cnrl from the aliphatic polyphthalate component is derived from the amine group. The ratio of the absorbance (Α·) in the vicinity of 153Gem·! of the acid component is (A^o/A]53. ) is preferably 〇.4〇~us. When the optical functional layer is laminated on the matte film, the photocurable resin constituting the optical functional layer shrinks during hardening or swells during high-temperature and high-humidity treatment, and strong stress is generated between the optical functional layer and the coating layer. . When the laminated film is dissolved under high temperature and high humidity, the coating layer is deteriorated by dissolution or seizure or hydrolysis due to dissolution contained in the graded type. The freshness causes the above-mentioned stress to be disengaged, so that the optical functional layer is peeled off, and the adhesion is lowered. Therefore, in order to maintain the adhesion under high temperature and high humidity for the same degree, it is believed that only II is crosslinked (four) coated layer. And give the wealth 11 = not enough 'required that it has the flexibility to get the above stress = 'If only soft, in the resistance ship (four) degree will have

It is believed that one t is most desirable to take into account these opposite characteristics. Therefore, my A acid SI tree:, the composition of the second == external spectral characteristics as an amine-based car also achieves softness and durability ==_化咖魏时峨 and high temperature secret == stress, so use various The light-hardening type of resin can be well-matched, even after 12/48 201233550 (bendingvibration). Therefore, the absorbance (eight 460) in the vicinity of 1460 cm-1 depends on the amount of the aliphatic polycarbonate polyol component constituting the urethane resin present in the coating layer. On the other hand, the nearby absorbance (A1530) is derived from the bending vibration peculiar to the N-H bond contained in the urethane component. Therefore, the size of the absorbance (A153〇) in the vicinity of 1530 cm-1 depends on the amount of the amino phthalate component (the number of amino phthalate bonds) constituting the amino phthalate resin present in the coating layer. Further, when an isocyanate crosslinking agent is used as a crosslinking agent, the amount of absorbance (A153G) in the vicinity of 1530 cm·1 depends on the sum of the amount of the amine phthalate resin and the crosslinking agent present in the coating layer. The amount of the amino phthalate component (the number of amino phthalate linkages). Therefore, the ratio of absorbance (A, partial/eight) is such that two components having different characteristics coexist in a specific ratio. In the present invention, the ratio (A146()/a153〇) is 0.40 to 1.55', and the lower limit of the ratio (A^o/Awo) is preferably ο,#, more preferably 0.50. Further, the upper limit of the ratio (eight pastes/eighths) is preferably i so, more preferably 1.4G', still more preferably 丨.30, and particularly preferably (3). When the ratio (Ah^/A^so) is less than 0_40, the amount of the rigid amino phthalate component is too large, so that the stress relaxation of the coating layer is lowered, and the moist heat resistance is lowered. Further, when the ratio (A^o/A^o) exceeds 1.55, the aliphatic component of the soft aliphatic polyphthalate is excessively large, thereby lowering the solvent resistance of the coating layer, and = having heat and humidity resistance. Reduced situation. The aliphatic alicyclic polycarbonate polyol may, for example, be a fatty acid ester diol or an aliphatic polycarbonate triol, and is preferably a polycarbonate diol. The urethane tree of the present invention: an aliphatic polycarbonate diol can be exemplified by, for example, i, 赛成夕 N 13⁄4 - 3C-1,3-propanediol, 1,4-butanediol, 〗 〖 -Pentanediol, 3_Metformin-1,5-pentyl·13/48 201233550 1,6-hexanediol, 1,9-nonanediol, hydrazine, 8-decanediol, neopentyl glycol One or two or more kinds of diols such as diethylene glycol, dipropylene glycol, 1,4-cyclohexane diol, hydrazine hexahydromethane, and the like, and, for example, dimercaptocarbonate, diphenyl An aliphatic fluorene-based polycarbonate diol obtained by reacting carbonate carbonate or a carbonate such as ethylene carbonate or carbon ruthenium chloride. The number average molecular weight of the aliphatic polycarbonate diol is preferably from 1,500 to 4,000, more preferably from 2,000 to 3,000. When the number average molecular weight of the aliphatic polycarbocarbonate is small, the proportion of the aliphatic polycarbonate component constituting the amine methyl ester resin is relatively small. Because the ratio (??) is within the above range, the number average molecular weight of the aliphatic polycarbonic acid from the diol can be controlled within the above-mentioned turning. The number average molecular weight of the aliphatic polycarbonate S diol, the absorbance (a^q) in the vicinity of 1460 CHT1 derived from the aliphatic polycarbonate component increases, and the aliphatic component increases, and the solvent resistance is lowered and dense. When the number-average molecular weight of the hydrazine-based aliphatic polycarbonate S-diol is small, the amount of the amine-based amic acid is increased, and the stress caused by the shrinkage of the photocurable resin or the like cannot be alleviated. The case where the adhesion is lowered. The polyisocyanuric acid vinegar of the constituent component of the urethane carboxylic acid resin of the present invention may, for example, be an exogenous diisocyanic acid vinegar of the diisocyanate; And an alicyclic diisoxamic acid lysine of 4,4·dicyclohexylmethylammonium diisocyanate, U·bis (isocyanate), cyclohexanyl, etc.; Aliphatic diisochrome of vinegar and 2,2,4•trimethylhexamethylene diisocyanate _ or the like, or a mono- or complex (IV) compound firstly added with trihydroxy hydrazine propane or the like Polyisocyanates. When the use of aromatic isocyanic acid is used, there is a problem of yellowing, which may be undesirable in optical applications requiring high transparency. Moreover, since the coating film 14/48 201233550 is harder than the fat _ system, it is not able to alleviate the adhesion due to the light. The shrinkage of the light==4, the swelling caused by the bright (four) adjustment ° the key of the hair Examples of the extender include ethylene glycol, diethylene glycol, i 4 -butanediol, neopentyl glycol, and diols of hexamethylene glycol, glycerol, and trishydroxyl =., and various types of pentaerythritol, such as ethylenediamine, hexamethylenediamine, and sulphide); thiol of monoamines such as monoethanolamine and diethanolamine; Glycols, or water. However, when the primary bond extender is used, 153 (near the vicinity of W) derived from the amino-based component may increase, and the flexibility of the coating layer may be lowered. Because of the steep old age, the end of the chain is good for the main chain. Further, the flexibility of the coating layer is preferably 1, preferably an aliphatic or a chain length of 2% by weight of the main chain of 4 to H) or a chain extender of a diamine. In this case, the chain extender is preferably a coating layer of ruthenium butanediol, W hexanediol or hexamethylenediamine. Preferably, the coating liquid is applied by a line 后 H described later. Therefore, the amino acid sulfonate S resin of the present invention is preferably water-soluble. The term "water-soluble" as used in the description means an aqueous solution which is dissolved in water or an organic solvent containing water in an amount of 5 mass% or less. It is water-soluble for the amine-based resin, and it can be used as an acid-based sulfonate. Continued acid (salt) soil is strong Ml ' Because it can absorb moisture, it is difficult to change the moisture resistance, 2 is the test of the leg (salt). In addition, it can also lead to the non-ionic group of polyoxymethane. In order to introduce a slow acid (salt) group into the amino carboxylic acid vinegar resin, for example, a dimer methyl methacrylate having a Wei group as a polyol component, a ruthenium 15/48 201233550 butylbutyric acid, or the like may be mentioned. The polyol compound is introduced as a copolymerization component, and then neutralized by a sputum forming sword. Specific examples of the salt forming agent include, for example, trimethyl amide such as aminodimethylamine, triethylamine, triisopropylamine, tri-n-propylamine, and tri-n-butylamine; N•methylmorphine, N-dialkylalkanol, such as N-ethyl linlin, etc., N-dialkylalkanol, etc. This temple can be used alone or in combination of two or more. When a polyol compound having a few acid (salt) groups is used as a copolymerization component in order to impart water hydrazine n, the composition of the polyol compound in the amino amide resin is a molar ratio of the urethane. When the total amount of the polyglycolic acid vinegar component is 100% by mole, it is preferably 3 to 60% by mole, more preferably 5 to 40% by mole. When the composition Mohr ratio is less than 3 mol%, the water dispersibility is mixed. Further, when the domain molar ratio exceeds 60 mol; /°, the water resistance is lowered, so that the moist heat resistance may be lowered. The conversion temperature of the carbamic acid g|turn of the present hair is preferably lower than ‘more preferably lower than 〇t. The glass transition temperature is lower than the coating stress relaxation, and it is preferred that the glass transition temperature is light. Further, it is preferable that the urethane resin is contained in an amount of 80% by mass or less with respect to the cross-linking agent, especially for the lens. Amine (tetra) acid The dendrite of the temple will decrease under the same temperature and south, and vice versa. It can also be mentioned! The 'resistance' can be introduced into the urethane resin itself in addition to the agent in the present invention. Hunting increases the degree of cross-linking of the resin and enhances the solvent. The self-crosslinking group used in the present invention is not particularly limited, and a stanol group which is stable even in the aqueous coating liquid of 16/48 201233550 can be preferably used. In order to improve the adhesion, the amino phthalate resin of the present invention may contain two or more kinds. In order to improve the adhesion, a resin other than the amino phthalate resin of the present invention may be contained. For example, an acrylic resin, a polyester resin, etc. are mentioned. (Blocked isocyanate) In the present invention, the dissociation temperature in the coating layer was 13 Å. The following is the case that the block isocyanate having a boiling point of 8 〇t: or more is necessary. The blocked isocyanate is obtained by reacting a polyisocyanate with a block agent. Further, the dissociation temperature and boiling point can be measured by differential thermal analysis. The dissociation temperature of the blocked isocyanate is preferably 13 (rc or less, more preferably 125 C or less and even more preferably 120 C or less). The block agent is formed on a film when the coating liquid is subjected to a drying step after coating or a line coating method. In the membrane step, heating is carried out to dissociate from the functional group, and regenerated isocyanic acid is generated. Therefore, the crosslinking reaction is carried out with an amino group, a lipid, etc., and the adhesion under normal temperature and high temperature 'wet is improved. When the temperature of the above-mentioned temperature is less than the above temperature, the New Zealand will be charged, so the heat resistance will be better. The upper limit of the dissociation temperature is only room temperature for the liquidization of the coating liquid. The above may be no special mosquito, preferably more than the machine, more preferably 60 C or more, and even more preferably 8 〇 or more. The block agent is preferably a compound having one active hydrogen in the molecule. The dissociation temperature is relatively low as described above, and it is preferred to use a block agent which can obtain a high electron density. It is preferable to use a block agent having a heterocyclic ring or a similar structure in the molecule, etc. " The stagnation point of the segmenting agent is preferably 18 (rc or more, more preferably (10). c is above 5 17/4. 8 201233550 More preferably 200. 〇 Above 'Easy is 21〇u upper high' in the drying solution of the coating liquid after coating or line field 2 = boiling point is higher than the heating of the film film step, can also suppress the embedded The coating surface of the coating agent may have a small appearance and transparency of the coated surface due to the unevenness of the coated surface. The upper limit of the button (4) and the upper limit of the coating yield of I liter are preferably about 3 GGt. Since the boiling point of the block agent is increased by the two females, it is preferable that the molecular weight of the embedded octagonal mountain portion agent having a large amount of time is preferably 50 or more, and more preferably 6 〇 or more. Dan et al. are the dissociation temperature used in the block isocyanate of the present invention, and the boiling point of the block agent is 18 (the block agent above rc is exemplified by a bisulfite compound: sodium hydrogen sulfite).

In view of transparency, adhesion, and heat and humidity resistance, aliphatic, alicyclic isocyanate or the like is preferred. When using aromatic isocyanic acid, there is a problem of yellowing, which may be a poor condition for optical applications requiring high transparency. Further, since the coating film is harder than the aliphatic film, the stress due to shrinkage or swelling of the photocurable resin or the like cannot be alleviated, and the adhesion may be lowered. / In order to impart water solubility or water dispersibility to the blocked isocyanate of the present invention, the polyisocyanate g of the other body may be a hydrophilic group.

Among them, the ionic ionicity of the other water-containing resin is mostly, and it is difficult to be an anionic scaly ionic which can be easily seen. Further, since the pigmentation property is excellent in compatibility with other trees 19/48, 201233550, nonionics are preferred in terms of improving heat and humidity resistance. Further, in the case of the water-based nature, the above-mentioned h non-ionic transparency and appearance anionic water-based water-based poly-trimethane can be imparted to the following: :r-oxybutyric acid, oxyvaleric acid, and acid group Poly, in order to neutralize the compound. For example, ammonia, methylamine, ethylamine, butylamine, 2-ethylhexylamine, cyclohexylamine, dimethylamine, propylamine, acetophenone, and butyl hydrazine _ makeup-ethylamine, bis-butane Wide-bonded, branched, grade 1 and bis-'-amines with a carbon number of 1 to 20, such as butyl makeup, triterpene, triethylamine, triisopropylamine, and 2 nucleus; a hydroxylamine having a ratio of cyclic amine, mono-mercaptoethanolamine, mercaptoisopropanolamine, dimercaptoethanolamine, diethanolamine, triethanolamine, diethylethanolamine, etc. Etc., a nonionic hydrophilic group, preferably a repeating unit of ethylene oxide and/or propylene oxide of a polyethanol polypropylene glycol end-capped with an alkane group, ^ 2 \L· ^ ^ Wenjia is 5 to 30. When the repeating unit is small, the compatibility with the resin is inferior, and the degree is increased; when the repeating unit is large, there is a case where the adhesion under high temperature and high humidity is low. A nonionic, anionic, cationic or amphoteric surfactant may be added to the water dispersibility of the isocyanate, and examples thereof include polyethylene glycol and polyhydric alcohol fatty acid ester.
