The present invention relates to a composition formulated to prevent discoloration and fading of a polymeric material containing a pigment. More specifically, the present invention relates to a polymer material composition containing a UV absorber, which is a light stabilizer, and a piperidine derivative. The purpose is to maintain the initial color tone of the polymer molded article containing the pigment. Polymer materials have excellent physical and chemical properties, making them ideal for molded products, tapes, etc.
It is consumed in large quantities for textiles, films, etc., and the demand for it is increasing year by year. These polymeric materials are characterized by the fact that they can be easily colored with pigments, dyes, etc., and when they are consumed as molded products, tapes, fibers, films, etc., they are usually colored with pigments, dyes, etc. There are many. However, pigments and paints blended into polymeric materials have the disadvantage that their color tone changes during storage and use due to sunlight, ultraviolet rays, etc., and this change in color tone impairs their commercial value. Therefore, it is extremely important industrially to prevent changes in the initial color tone of polymeric materials containing pigments, dyes, etc. Conventionally, inorganic pigments containing cadmium, lead, chromium, etc., which are known to be effective against such defects, are extremely excellent and are not easily affected by sunlight or ultraviolet rays. , chromium, etc. are harmful, and there are problems when incinerating or disposing of polymeric materials containing inorganic pigments containing cadmium, lead, chromium, etc. after use, and restrictions on their use are becoming increasingly strict. ing. The present invention replaces inorganic pigments containing cadmium, lead, chromium, etc., which have excellent discoloration and fading effects due to sunlight or ultraviolet rays, with inorganic and organic pigments, especially organic pigments, that do not contain cadmium, lead, chromium, etc. This objective is attempted to be achieved by combining and simultaneously blending a known ultraviolet absorber and a light stabilizer, which is a piperidine derivative, to counteract the discoloration and fading that occurs in such cases. A light stabilizer added to a polymeric material to prevent discoloration and fading of inorganic and organic pigments that do not contain cadmium, lead, chromium, etc. in the composition of the present invention. As a UV absorber, the following formula (A) (However, in the formula, R 1 , R 2 and R 3 are hydrogen atoms,
It represents a hydroxyl group, a halogen atom, an alkyl group having 1 to 6 carbon atoms, or an alkoxy group having 1 to 12 carbon atoms. ) A benzophenone derivative represented by the following formula (B) (However, in the formula, R 4 , R 5 and R 6 are hydrogen atoms, halogen atoms, alkyl groups having 1 to 6 carbon atoms, cycloalkyl groups, or 7 to 12 carbon atoms.

One or two selected from piperidine derivatives per 100 parts by weight of the total amount of UV absorbers
In the case of one or more species, 5 to 300 parts, preferably 20 parts
~100 copies, in the case of two or more types, the total is 20-600 copies,
It is preferably blended at a concentration of 30 to 200 parts. This ratio is preferable because it is less than 5 and 20 parts or
This is because a sufficient synergistic effect is not observed when the amount exceeds 300 and 600 parts. The light stabilizer combination is used in a concentration of 5 to 200 parts, preferably 10 to 100 parts per 100 parts by weight of pigment.

Polyolefins such as propylene homopolymers, copolymers of propylene and ethylene, other olefins, etc. are suitable. The inorganic and organic pigments and light stabilizers that do not contain cadmium, lead, chromium, etc. of the present invention can be easily added to polymeric materials using known methods such as mixing rolls, Banbury mixers, mixers, extruders, etc. It is done. Alternatively, a highly concentrated masterbatch may be prepared in advance and blended. Furthermore, in the present invention, combinations with commonly used additives such as oxidation stabilizers, neutralizing agents, fillers, vulcanization accelerators, lubricants, antistatic agents, antiblocking agents, copper damage inhibitors, resin plasticizers, etc. It is okay to use it. The present invention will be explained in detail below using examples, but these examples are intended to simplify the understanding of the present invention and are not intended to limit the scope of the invention. Examples 1 to 4, Comparative Example 1 Polypropylene powder (Sumitomo Chemical, intrinsic viscosity
2.0), along with the pigments, light stabilizers, and piperidine derivatives shown in Table 1 (other than pigments are indicated by the numbers attached to the above compounds), 100 parts by weight of polypropylene was added for the purpose of preventing significant deterioration of the resin in the extruder. 0.2 parts by weight of 2,6-di-tert-butyl-4-methylphenol, 0.2 parts by weight of distearyl thiodipropinate, and 0.2 parts by weight of calcium stearate were added to the mixture and mixed for 10 minutes using a Henschel mixer. This mixture was heated to a cylinder temperature of 220℃, L/D=
The mixture was melt-kneaded and granulated using an extruder with a diameter of 18 and 30 mm. The pellets were preheated for 5 minutes using a hot press at 220°C, pressed for 5 minutes (100 kg/cm 2 ), and cooled for 2 minutes using a water-cooled press at 30°C to produce a pressed sheet with a thickness of 1 mm. The chromaticity of this press sheet was measured using a color difference meter manufactured by Koon Seisakusho, and the yellowness index (YI) was calculated using the following formula (1). YI=100(1.28x-1.06z)/y (1) (However, x, y, and z are the tristimulus values of the test piece in standard light C.) This value is taken as the initial yellowness. In addition, this press sheet was irradiated for 500 hours using a Shimadzu weather tester, and then the yellowness was calculated using the same method. The larger the yellowness value, the more yellow it is. If there is a difference of 3.0 or more in this value, it can be clearly identified with the naked eye. Therefore, the smaller the difference in yellowness between the initial stage and after irradiation with the weather tester, the less change in color tone.

The chromaticity of this press sheet was measured using a color difference meter manufactured by Koon Seisakusho, and the whiteness (W) was calculated using the following formula (2). This whiteness is taken as the initial whiteness. W=100−√( 2 + 2 )+(100−) 2 (2) (L is the lightness, a is the chromaticity along the red-green axis, and b is the chromaticity along the yellow-blue axis. ) This press sheet was irradiated for 500 hours using a weather tester manufactured by Toritsu Seisakusho, and the whiteness was calculated using the same method. The larger the whiteness value, the closer to pure white it is. All examples show that there was no change in color tone compared to the comparative example.
