Title: Ultraviolet absorbent composition

Description:
TECHNICAL FIELD 
     The present invention relates to an ultraviolet absorbent composition. More specifically, the present invention relates to an ultraviolet absorbent composition that causes neither deposition of an ultraviolet absorbent nor bleed-out owing to a long-term use, and that is excellent in a long-wavelength ultraviolet absorption capability as well as light stability by virtue of maintaining the capability for a long period of time. 
     BACKGROUND ART 
     Ultraviolet absorbents have been used in combination with various resins for providing the resins with ultraviolet-absorptivity. Both inorganic and organic ultraviolet absorbents are used. The inorganic ultraviolet absorbents (see, for example, JP-A-5-339033 (“JP-A” means unexamined published Japanese patent application), JP-A-5-345639 and JP-A-6-56466) are superior in durability such as weather resistance and heat resistance. However, the freedom in selecting the compound is limited, because the absorption wavelength is determined by the band gap of the compound. In addition, there is no inorganic absorbent that absorbs the light in a long-wavelength ultraviolet (UV-A) range of 320 to 400 nm. And any such absorbent that absorbs long-wavelength ultraviolet would have color because it would have absorption also in the visible range. 
     In contrast, the freedom in designing the absorbent structure is much wider for organic ultraviolet absorbents, and thus, it is possible to obtain absorbents having various absorption wavelengths by designing the absorbent chemical structure properly. 
     Various organic ultraviolet absorbent systems have been studied, and for absorption in the long-wavelength ultraviolet range, it is conceivable either to use an absorbent having the wavelength of maximal absorption in the long-wavelength ultraviolet range or to use a high concentration of absorbent. However, the absorbents described in, for example, JP-A-6-145387 and JP-A-2003-177235 having the wavelength of maximal absorption in the long-wavelength ultraviolet range are inferior in light stability, and their absorption capability declines with time. 
     In contrast, benzophenone- and benzotriazole-based ultraviolet absorbents are relatively higher in light stability, and increase in concentration or film thickness leads to relatively clean blocking of the light in the longer-wavelength range (see, for example, JP-T-2005-517787 (“JP-T” means published Japanese translation of PCT application) and JP-A-7-285927). However, when such an ultraviolet absorbent is applied as mixed with a resin or the like, the film thickness is limited to several tens of μm at the most. For utilizing the film thickness to block the light in the longer-wavelength range, it is necessary to add the ultraviolet absorbent to a considerably high concentration. However, simple addition of highly-concentrated ultraviolet absorbent only results in a coloring problem. There are some ultraviolet absorbents that are irritative to skin and accumulate in the body among the benzophenone- and benzotriazole-based ultraviolet absorbents, and thus, intensive care should have been given to these compounds in use. Further, JP-A-60-170842 and JP-B-49-11155 (“JP-B” means examined Japanese patent publication) each describe five-membered ring compound containing two sulfur atoms. The ultraviolet absorbent contained in the ultraviolet absorbent composition of the present invention has a sharp waveform, and is able to absorb ultraviolet light up to a long-wavelength range. Accordingly, the ultraviolet absorbent used in the present invention has an advantage that there is no possibility of coloring, when compared to known ultraviolet absorbents described above. 
     Various kinds of additives are added to polymer materials or resins to prevent them from deterioration. The deterioration of the polymer material is essentially caused by autoxidation. In many polymer materials, inhibition of the autoxidation has been tackled by adding thereto several kinds of additives selected from an ultraviolet absorbent, an antioxidant, a peroxide decomposer, a radical inhibitor, a metal deactivator, an acid trapping agent and the like (JP-A-2008-52041 and JP-A-2004-117997). However, it is known that when an ultraviolet absorbent and other additives are simply added to a polymer material, reduction of compatibility with the polymer generally causes such a phenomenon that particles come up to the polymer surface, namely “bleed out”. In the ultraviolet absorbent used in the present invention that is able to absorb ultraviolet light up to a long-wavelength ultraviolet range (UV-A), problems also arise that when the ultraviolet absorbent is simply mixed with other proper additives to form a mixture, compatibility of the formed mixture at the time of addition to the polymer and solubility of the formed mixture at the time of dissolution to a solvent become insufficient, and consequently solid deposits, which results in a powder-mottled polymer material.

Hammett in 1935 for quantitatively considering the effect of substituents on the reaction or equilibrium of benzene derivatives, and the appropriateness thereof is now widely recognized. The substituent constant determined in the Hammett&#39;s rule involves σ p  value and σ m  value. These values can be found in a multiplicity of general publications, and are detailed in, for example, “Lange&#39;s Handbook of Chemistry” 12th edition by J. A. Dean, 1979 (McGraw-Hill), “Kagaku no Ryoiki” special issue, No. 122, pp. 96 to 103, 1979 (Nankodo) and Chem. Rev., vol. 91, pp. 165 to 195, 1991.

Rev., 1991, vol. 91, pp. 165 to 195.

     X B1 , X B2 , X B3  and X B4  each independently represent a hetero atom. Examples of the hetero atom include a boron atom, a nitrogen atom, an oxygen atom, a silicon atom, a phosphorus atom, a sulfur atom, a selenium atom, and a tellurium atom. X B1 , X B2 , X B3  and X B4  each are preferably a nitrogen atom, an oxygen atom or a sulfur atom; more preferably a nitrogen atom or a sulfur atom; and particularly preferably a sulfur atom. 
     X B1 , X B2 , X B3  and X B4  may be different from each other, but the combination of X B1  and X B2  and the combination of X B3  and X B4  are preferably the same as each other. Most preferably, all groups each represent a sulfur atom. 
     Typical favorable examples of the combination of X B1  and X B2  or the combination of X B3  and X B4  are shown in the following Table 3, but the present invention is not restricted thereby. Ac represents an acetyl group in the present description. The wavy line in the Table indicates the binding site on the carbon atoms in formula (B-I) to which R B1  and R B2  or R B3  and R B4  bind.

     The ultraviolet absorbent represented by formula (B-I) is preferably an ultraviolet absorbent represented by formula (B-Ia). 
     
       
         
         
             
             
         
       
     
     In formula (B-Ia), R Ba1 , R Ba2 , R Ba3  and R Ba4  each represent a monovalent substituent. However, at least one of R Ba1 , R Ba2 , R Ba3  and R Ba4  represents a cyano group, an alkoxycarbonyl group having 1 to 20 carbon atoms (preferably 1 to 10 carbon atoms), an aryloxycarbonyl group having 6 to 20 carbon atoms (preferably 6 to 10 carbon atoms), a carbamoyl group having 1 to 20 carbon atoms (preferably 1 to 10 carbon atoms), an alkylcarbonyl group having 1 to 20 carbon atoms (preferably 1 to 10 carbon atoms), an arylcarbonyl group having 6 to 20 carbon atoms (preferably 6 to 10 carbon atoms), an alkylsulfonyl group having 1 to 20 carbon atoms (preferably 1 to 10 carbon atoms) or an arylsulfonyl group having 6 to 20 carbon atoms (preferably 6 to 10 carbon atoms). 
     It is preferable that R Ba1 , R Ba2 , R Ba3 , and R Ba4  are a monovalent substituent by which at least one of the combination of (R Ba1 , R Ba2 ) and the combination of (R Ba3 , R Ba4 ) form no ring. 
     It is especially preferable that each of R Ba1 , R Ba2 , R Ba3 , and R Ba4  is a monovalent substituent by which neither the combination of (R Ba1 , R Ba2 ) nor the combination of (R Ba3 , R Ba4 ) forms a ring. 
     Absence of ring formation provides such advantages that the ultraviolet absorbent is able to exhibit an excellent long-wavelength ultraviolet absorption capability, and also a self-yellow color development of the ultraviolet absorbent can be prevented. Further, absence of ring formation provides such advantages that the ultraviolet absorbent is excellent in solubility in a solvent and compatibility with a polymer, compared to the case of ring formation. 
     In the present specification, examples of the monovalent substituent that does not form any ring include a straight-chain or branched alkyl group having 1 to 20 carbon atoms (preferably 1 to 10 carbon atoms) (e.g., methyl, ethyl), an aryl group having 6 to 20 carbon atoms (preferably 6 to 10 carbon atoms) (e.g., phenyl, naphthyl), a cyano group, an alkoxycarbonyl group having 1 to 20 carbon atoms (preferably 1 to 10 carbon atoms) (e.g., methoxycarbonyl), an aryloxycarbonyl group having 6 to 20 carbon atoms (preferably 6 to 10 carbon atoms) (e.g., phenoxycarbonyl), a substituted or unsubstituted carbamoyl group having 1 to 20 carbon atoms (preferably 1 to 10 carbon atoms) (e.g., carbamoyl, N-phenylcarbamoyl, N,N-dimethylcarbamoyl), an alkylcarbonyl group having 1 to 20 carbon atoms (preferably 1 to 10 carbon atoms) (e.g., acetyl), an arylcarbonyl group having 6 to 20 carbon atoms (preferably 6 to 10 carbon atoms) (e.g., benzoyl), a nitro group, a substituted or unsubstituted sulfamoyl group having 0 to 20 carbon atoms (preferably 0 to 10 carbon atoms) (e.g., sulfamoyl, N-phenylsulfamoyl), an alkylsulfonyl group having 1 to 20 carbon atoms (preferably 1 to 10 carbon atoms) (e.g., methansulfonyl), an arylsulfonyl group having 6 to 20 carbon atoms (preferably 6 to 10 carbon atoms) (e.g., benzenesulfonyl), and a four- to seven-membered (preferably five- to six-membered) heterocyclic group (e.g., pyridyl, morpholino). The substituent may be further substituted, and multiple substituents, if present, may be the same as or different from each other. 
     Herein, at least one of the monovalent substituents R Ba1 , R Ba2 , R Ba3  and R Ba4  is a cyano group, an alkoxycarbonyl group having 1 to 20 carbon atoms (preferably 1 to 10 carbon atoms), an aryloxycarbonyl group having 6 to 20 carbon atoms (preferably 6 to 10 carbon atoms), a carbamoyl group having 1 to 20 carbon atoms (preferably 1 to 10 carbon atoms), an alkylcarbonyl group having 1 to 20 carbon atoms (preferably 1 to 10 carbon atoms), an arylcarbonyl group having 6 to 20 carbon atoms (preferably 6 to 10 carbon atoms), an alkylsulfonyl group having 1 to 20 carbon atoms (preferably 1 to 10 carbon atoms) or an arylsulfonyl group having 6 to 20 carbon atoms (preferably 6 to 10 carbon atoms). 
     R Ba1 , R Ba2 , R Ba3  and R Ba4  each are particularly preferably selected from a cyano group, an alkoxycarbonyl group having 1 to 20 carbon atoms (preferably 1 to 10 carbon atoms), an aryloxycarbonyl group having 6 to 20 carbon atoms (preferably 6 to 10 carbon atoms), a carbamoyl group having 1 to 20 carbon atoms (preferably 1 to 10 carbon atoms), an alkylcarbonyl group having 1 to 20 carbon atoms (preferably 1 to 10 carbon atoms), an arylcarbonyl group having 6 to 20 carbon atoms (preferably 6 to 10 carbon atoms), an alkylsulfonyl group having 1 to 20 carbon atoms (preferably 1 to 10 carbon atoms) or an arylsulfonyl group having 6 to 20 carbon atoms (preferably 6 to 10 carbon atoms). It is more preferable that a pair of R 1a  and R 2a , and a pair of R 3a  and R 4a  are the same in terms of combination of the members in each pair. 
     R Ba5  and R Ba6  each represent an alkoxy group having 1 to 20 carbon atoms (preferably 1 to 10 carbon atoms), an acyloxy group having 6 to 20 carbon atoms (preferably 6 to 10 carbon atoms), an acyloxy group having 1 to 20 carbon atoms (preferably 1 to 10 carbon atoms), an alkoxycarbonyloxy group having 1 to 20 carbon atoms (preferably 1 to 10 carbon atoms), an aryloxycarbonyloxy group having 6 to 20 carbon atoms (preferably 6 to 10 carbon atoms), a carbamoyloxy group having 1 to 20 carbon atoms (preferably 1 to 10 carbon atoms), an amino group having 0 to 20 carbon atoms (preferably 0 to 10 carbon atoms), an acylamino group having 1 to 20 carbon atoms (preferably 1 to 10 carbon atoms), or a carbamoylamino group having 1 to 20 carbon atoms (preferably 1 to 10 carbon atoms). 
     R Ba5  and R Ba6  may further have a substituent. Examples of the substituent include the monovalent substituents described above. Examples of a bivalent substituent include a carbonyl group and an imino group. Multiple substituents, when present, may be the same as or different from each other. The substituents may bind to each other, forming a fused ring or a spiro ring. 
     Hereinafter, typical examples of the ultraviolet absorbent represented by formula (B-I) or (B-Ia) that can be used in the present invention will be described below, but the present invention is not restricted thereby. 
     
       
         
         
             
             
         
       
       
         
         
             
             
         
       
       
         
         
             
             
         
       
       
         
         
             
             
         
       
       
         
         
             
             
         
       
       
         
         
             
             
         
       
       
         
         
             
             
         
       
       
         
         
             
             
         
       
       
         
         
             
             
         
       
       
         
         
             
             
         
       
       
         
         
             
             
         
       
       
         
         
             
             
         
       
       
         
         
             
             
         
       
       
         
         
             
             
         
       
       
         
         
             
             
         
       
       
         
         
             
             
         
       
     
     The ultraviolet absorbent represented by formula (B-I) or (B-Ia) above can be synthesized by any method.

In addition, even if a mixture of the geometrical isomers is formed in the preparative or purification process, only a typical isomeric structure is shown in the present specification. When the compound is a geometrical isomer mixture, the abundance ratio is arbitrary between 0:1 to 1:0. 
     The ultraviolet absorbent represented by any one of formulae (2), (3), (4), (5), (B-I) and (B-Ia) that can be used in the present invention may have a tautomer, depending on its structure and the environment to which the compound is exposed. In the present specification, only a typical tautomer is described, but other tautomers different from that described in the present specification are also included in the ultraviolet absorbent that can be used in the present invention compound. 
     The ultraviolet absorbent represented by any one of formulae (2), (3), (4), (5), (B-I) and (B-Ia) that can be used in the present invention may have an isotopic element (such as  2 H,  3 H,  13 C,  15 N,  17 O, or  18 O).

R 97 , R 98 , and R 99 , which may be the same as or different from each other, each independently represent an alkyl group, an alkenyl group, an aryl group, an alkoxy group, an alkenyloxy group, or an aryloxy group. —X 91 — represents —O—, —S—, or —N—(R 100 )—, in which R 100  has the same meaning as R 91 . R 92 , R 93 , R 94 , R 95  and R 96 , which may be the same as or different from each other, each independently represent a hydrogen atom, or a substituent. However, all of R 91 , R 92 , R 93 , R 94 , R 95 , R 96  and R 100  cannot simultaneously represent a hydrogen atom, respectively, and the total number of carbon atoms is 10 or more. 
     When the group in the present specification contains an aliphatic moiety, the aliphatic moiety may be straight chain-like, branched chain-like, or cyclic, and saturated or unsaturated. Examples of the aliphatic moiety include alkyl, alkenyl, cycloalkyl, and cycloalkenyl moieties, each of which may be non-substituted, or substituted with a substituent. Further, when the group contains an aryl moiety, the aryl moiety may be a single ring or a fused ring, each of which may be non-substituted, or substituted with a substituent. Further, when the group contains a heterocyclic moiety, the heterocyclic moiety contains a hetero atom (for example, a nitrogen atom, a sulfur atom, an oxygen atom) in the ring, and may be a saturated ring, or an unsaturated ring, and may be a single ring or a fused ring, each of which may be non-substituted, or substituted with a substituent. The substituent may bind with a hetero atom, or a carbon atom in the ring. 
     The substituent used in the present invention is not particularly limited, as long as it is a replaceable group. Examples thereof include an aliphatic group, an aryl group, a heterocyclic group, an acyl group, an acyloxy group, an acyl amino group, an aliphatic oxy group, an aryloxy group, a heterocyclic oxy group, an aliphatic oxycarbonyl group, an aryloxycarbonyl group, a heterocyclic oxycarbonyl group, a carbamoyl group, an aliphatic sulfonyl group, an arylsulfonyl group, a heterocyclic sulfonyl group, an aliphatic sulfonyloxy group, an arylsulfonyloxy group, a heterocyclic sulfonyloxy group, a sulfamoyl group, an aliphatic sulfonamido group, an arylsulfonamido group, a heterocyclic sulfonamido group, an aliphatic amino group, an arylamino group, a heterocyclic amino group, an aliphatic oxycarbonylamino group, an aryloxycarbonylamino group, a heterocyclic oxycarbonylamino group, an aliphatic sulfinyl group, an arylsulfonyl group, an aliphatic thio group, an arylthio group, a hydroxy group, a cyano group, a sulfo group, a carboxyl group, an aliphatic oxyamino group, an aryloxyamino group, a carbamoylamino group, a sulfamoylamino group, a halogen atom, a sulfamoyl carbamoyl group, a carbamoyl sulfamoyl group, a phosphinyl group, and a phosphoryl group.

R 97 , R 98 , and R 99  may be the same as or different from each other. R 97 , R 98 , and R 99  each represent an alkyl group (e.g., a methyl group, an ethyl group, a t-butyl group, a benzyl group), an alkenyl group (e.g., an allyl group), an aryl group (e.g., a phenyl group), an alkoxy group (e.g., a methoxy group, a butoxy group), an alkenyloxy group (e.g., an allyloxy group) or an aryloxy group (e.g., a phenoxy group). It is not preferable that the group is a phosphinotolyl group or a phosphinyl group because these groups are inferior in solubility in a solvent and compatibility with a polymer. 
     —X 91 — represents —O—, —S— or —N(—R 100 )—. R 100  has the same meaning as that of R 91 , and preferable ranges thereof are also the same. R 92 , R 93 , R 94 , R 95  and R 96 , which may be the same as or different from each other, each independently represent a hydrogen atom or a substituent. Examples of the substituent include a hydrogen atom, an alkyl group (including a cyclic alkyl group such as a cycloalkyl group, a bicycloalkyl group and a tricycloalkyl group), an alkenyl group (including a cyclic alkenyl group such as a cycloalkenyl group, a bicycloalkenyl group and a tricycloalkenyl group), an alkynyl group, an aryl group, a heterocyclic group, a cyano group, a hydroxyl group, a nitro group, a carboxyl group, an alkoxy group, an aryloxy group, a silyloxy group, a heterocyclic oxy group, an acyloxy group, a carbamoyloxy group, an alkoxycarbonyloxy group, an aryloxycarbonyloxy group, an amino group (including an anilino group), an acylamino group, an aminocarbonylamino group, an alkoxycarbonylamino group, an aryloxycarbonylamino group, a sulfamoylamino group, an alkyl- or aryl-sulfonylamino group, a mercapto group, an alkylthio group, an arylthio group, a heterocyclic thio group, a sulfamoyl group, a sulfo group, an alkyl- or aryl-sulfinyl group, an alkyl- or aryl-sulfonyl group, an acyl group, an aryloxycarbonyl group, an alkoxycarbonyl group, a carbamoyl group, an aryl- or heterocyclic-azo group, an imido group, a phosphino group, a phosphinyl group, a phosphinyloxy group, a phosphinylamino group and a silyl group.

     It is not preferable that R 91  and R 92 , or R 100  and R 96 , or R 91  and R 100  bind together with each other to form a 5- to 7-membered ring (for example, a chromane ring, a morpholine ring) because these rings are inferior in solubility in a solvent and compatibility with a polymer. Further, it is also not preferable from viewpoints of solubility and compatibility that R 92  and R 93 , or R 93  and R 94  bind together with each other to form a 5- to 7-membered ring (for example, a chromane ring, an indane ring), a spiro ring or a bicycle ring. However, all of R 91 , R 92 , R 93 , R 94 , R 95 , R 96  and R 100  are not a hydrogen atom at the same time. The total number of carbon atoms is 10 or more, and preferably 16 or more.

     When the ultraviolet absorbent composition contains two or more compounds represented by the formula (TS-I) or (TS-II), the two or more compounds may be selected from the same family (for example, that is the case where the two compounds represented by the formula (TS-II) are used), or alternatively each of the two or more compounds may be selected from different families (for example, that is the case where one compound represented by the formula (TS-I) and another compound represented by the formula (TS-II) are used in combination). It is preferable that the two or more compounds, each of which is selected from different families, are used in combination. 
     In the present invention, two or more kinds of ultraviolet absorbents represented by formula (2) or (B-I) different in structure may be used in combination.

Two kinds (preferably three kinds) of ultraviolet absorbents when used in combination absorb ultraviolet ray in a wider wavelength range.

     From the consideration of the latitude of the molar extinction coefficient, benzotriazole-based, benzophenone-based, salicylic acid-based, acrylate-based and triazine-based compounds are preferable.

     Example 1 
     Preparation of Ultraviolet Absorbent Composition-Containing Polymer Film 
     Exemplified compound (S-01) was added to 50 g of polyethylene terephthalate so that transmittance at 400 nm is 1% at the time of 50 μm film production. Further, to the polyethylene terephthalate mixture, exemplified compound (TI-56) was added at a mass ratio of 1:1. After melt-kneading at 275° C., followed by cooling and centrifuging, UV agent-containing film (sample 1) was prepared. Similarly, sample films were prepared in accordance with combinations of the ultraviolet absorbents and exemplified compounds and mass ratio shown in Table 4 set forth below. Further, in the same way, sample films were prepared by using comparative compound (TX-1), (TX-2), or (TX-3), and in accordance with the compositions constructed of combinations shown in the following Table 4.

     Each of these sample films was photoirradiated by a xenon lamp at an illuminance of 170,000 lux for 40 hours, and the residual amount of the ultraviolet absorbent after irradiation was determined. The residual amount was calculated according to the following Formula: 
       Residual amount (%)=100×(100−Transmittance after irradiation)/(100−Transmittance before irradiation) 
     Herein, the transmittance in the light toughness test is a value measured at 425 nm. The results are shown in Table 4. The residual amount of each of samples 13 and 18 in Table 4 was not measured because these samples contain no ultraviolet absorbent. 
     As is apparent from the results in Table 4, it is understood that light toughness of each of samples 12 and 17 each free of the compound represented by the formula (TS-I) or (TS-II) is less than 80% in terms of residual ratio of the ultraviolet absorbent, whereas in each of the samples 1 to 11 of the present invention, the residual ratio of the ultraviolet absorbent in the ultraviolet absorbent composition is high. 
     In addition, it is found that even in the samples 14 to 16 and 19 to 21 each containing the comparative compound that does not fall within the formula (TS-I) or (TS-II), the residual ratio of the ultraviolet absorbent is also high. However, these samples caused coloring as shown in the below-described Examples 2 and 4. Further, these samples were inferior in compatibility as shown in the below-described Example 5. 
     Example 2 
     Preparation of Molded Plates 101 to 120 
     One (1) kg of a polymethyl methacrylate resin (PMMA) and 0.1 g of the composition sample 1 were agitated in a stainless steel tumbler for 1 hour. The resultant mixture was melted and blended by a vent extruder at 230° C. and extruded into pellets for molding by an ordinary method. The pellets were dried at 80° C. for 3 hours, and then, molded into molded plate 101 having a thickness of 3 mm by an injection molding machine. 
     Molded plates 102 to 111 were prepared in a similar manner to the molded plate 101, except that the composition sample 1 was replaced with each of the composition samples 2 to 11 in preparation of the molded plate 101. 
     Alternatively, molded plates 112, 114, 115, 117, 119 and 120 were prepared in a similar manner to the molded plate 101, except that the composition sample 1 was replaced with each of the composition samples 12, 14, 15, 17, 19 and 20 respectively in preparation of the molded plate 101. 
     (Evaluation) 
     The photo-irradiated molded plates were visually observed, and evaluated according to the following criterion: 
     ∘: No coloration is observed
 
Δ: A little coloration is observed
 
x Coloration is apparently observed
 
     The thus-obtained results are shown in Table 5.

     Example 3 
     Preparation of PET Films 201 to 211 
     A transparent coating consisting of 100 g of DIANAL LR-1065 (trade name, manufactured by Mitsubishi Rayon Co., 40% methylethylketone (MEK) solution of an acrylic resin) and 0.5 g of the composition sample 1 was applied on a 100 μm polyethylene terephthalate (PET) film to be a dry film thickness of approximately 30 μm with a bar coater, and dried to give PET film 201 having an ultraviolet-absorbing layer. 
     PET films 202 to 208 were prepared in a similar manner to the PET film 201, except that the composition sample 1 was replaced with each of the composition samples 2 to 8 respectively in preparation of the PET film 201. 
     Alternatively, PET films 213 and 218 were prepared in a similar manner to the PET film 201, except that the composition sample 1 was replaced with the composition sample 13 or 18 in preparation of the PET film 201. (Evaluation) 
     A solid image in magenta color was printed on an inkjet-recording paper and dried sufficiently by using an inkjet printer (PIXUS iP1500, trade name, manufactured by Canon), and the PET film prepared above was superposed and fixed thereon so that the ultraviolet-absorbing layer is the outermost layer. The film was adhered to a southward window glass with its PET film facing the light and left as it was for 12 weeks for a light-resistance test. 
     Significant discoloration was confirmed in the comparative PET films 213 and 218 by visual observation. In contrast, each of the PET films 201 to 208 having the ultraviolet-absorbing layer containing each of the ultraviolet absorbent composition samples 1 to 8 according to the present invention retained a color tone almost similar to that immediately after printing. It is understood that the polymer material according to the present invention containing the ultraviolet absorbent composition according to the present invention is also excellent as an ultraviolet-absorbing film for protection of a light-labile compound for an extended period of time. 
     Example 4 
     Preparation of PET Film (Samples 301 to 304) 
     Samples in which 1 g of each of the composition samples 5, 9, 14, and 19 was added to 150 g of polyethylene terephthalate were kneaded respectively at 270° C. by means of MiniLab melt-kneading machine manufactured by Haake. After that, these samples were pressed at 270° C. by means of a hot press machine to give PET film samples 301 to 304. The thus-prepared PET films were visually observed, and evaluated according to the following criterion: 
     ∘: No coloration is observed
 
Δ to x: Coloration is observed
 
     The thus-obtained results are shown in Table 6,

     As is apparent from the results in Table 7, it is understood that samples 401 to 411 of the present invention are superior in compatibility with a resin to comparative samples 412 and 417 in each of which a single ultraviolet absorbent is used; comparative samples 413 and 418 in each of which a single compound is used, but the ultraviolet absorbent is not contained; and comparative samples 414 to 416 and 419 to 421 in each of which the comparative compound is contained. Especially, it is understood that when the mixing ratio of the ultraviolet absorbent represented by the formula (2) or (B-1), and the compound represented by the formula (TS-I) or (TS-II) is 1:1, the resin has more uniform surface on which no particles are observed (evaluation ⊚). Further, it is understood that when a combination of the ultraviolet absorbent and the compound represented by the formula (TS-II), that is a more preferable embodiment of the present invention, is used, the resin has also more uniform surface on which no particles are observed (evaluation ⊚). 
     Example 6 
     Evaluation of Compatibility with Acrylic Resin 
     Transparent coating samples in which 5 g or 25 g of the composition sample 1 was added to 100 g of DIANAL LR-1065 (trade name, manufactured by Mitsubishi Rayon Co., 40% methylethylketone (MEK) solution of an acrylic resin) were coated on an 80 μm-polyethylene terephthalate (PET) film to be a dry film thickness of approximately 30 μm with a bar coater, and dried to give PET films (samples 501 and 502) each having an ultraviolet absorbing layer. PET films each having an ultraviolet absorbing layer (samples 503 and 504) were prepared in the same manner, except that the composition sample 1 was replaced by the composition sample 16. The thus-prepared PET films were visually observed to evaluate compatibility. 
     In the below-described Table 8, “∘” denotes a clear film, “Δ” denotes a film in which granular powder is slightly observed on the surface, and “x” denotes a film in which granular powder is apparently observed on the surface.

     As is apparent from the results in Table 8, it is understood that the ultraviolet absorbent composition of the present invention, when the proportion of which is 5% in the polymer, gives the PET film (sample 501) in which no granular powder is observed on the surface (evaluation ⊚). Further, it is understood that the sample 502 having an increased proportion of the ultraviolet absorbent composition (the proportion of the ultraviolet absorbent composition in the polymer is 25%), thereby enhancing ultraviolet-shielding capacity, also forms a film in which no bleed out is observed. In contrast, when the composition using the comparative compound not belonging to the present invention was mixed in a polymer, granular powder was observed on the polymer surface in spite of a low concentration (sample 503, evaluation x). Further, the high concentration of the ultraviolet absorbent composition gave a more powder-deposited film (sample 504, evaluation xx). 
     INDUSTRIAL APPLICABILITY
