Abstract

PURPOSE:To provide a brightened resin which is freed from the problems of ununiform brightening and spotting, by brightening a resin with a mixture of two or more bisbenzoxazolylstilbene compds. CONSTITUTION:A resin molding or an unmolded resin is brightened with a mixture of at least two, pref. at least three benzoxazolylstilbene compds. of formula I (wherein A is a benzene nucleus; R1, R2 are each 3C or higher alkyl; R3, R4 are each H, 3C or higher alkyl). Examples of the compds. of formula I are those of formulas II, III, IV, etc. Examples of the resins are natural resins and synthetic high-molecular compds. such as polyamide, polyethylene, polyvinyl chloride or polyurethane. Only when at least two symmetric or unsymmetrical alkylbenzoxazolylstilbene compds. wherein the alkyl group is 3C alkyl or higher are present in a mixed state in an org. solvent including a plasticizer and a liquid resin, the solubility can be greatly improved.

However, alkylbenzoxasilylstilbene compounds, including these products, generally have poor solubility in organic solvents or compatibility with resin materials, making it impossible to whiten the compounds by dissolving them in organic solvents or plasticizers. Compounds precipitate in the whitened resin material over time, causing uneven whitening and spots, necessitating considerable restrictions on its uses and usage.

In fact, the use of two or more types of bisbenzoxasilylstilbene compound-based fluorescent brighteners for whitening is prohibited under the Japanese Patent Publication No. 43.
Although it is described in Japanese Patent No. 4202, it is merely intended to increase the brightness by 8 degrees, and the disadvantages of this type of brightener as described above still exist. # In the whitening process,
Problems such as spots appearing after a few weeks or even months on a completely whitened product can have serious consequences.

As a result of intensive studies in order to eliminate such drawbacks of bisbenzoxasilylstilbene compounds, the present inventor has developed a benzoxasilylstilbene compound having an alkyl group having 3 or more carbon atoms in the benzene nucleus constituting the benzoxasilyl group. From K, it is preferable to mix more than one type, preferably three or more types, and moreover, each compound accounts for about 1 to 80% (in terms of molar ratio) of the total bisbenzoxasilylstilbene compound, preferably 4 to 50 parts (in terms of molar ratio). It was discovered that when mixed, the solubility of bisbenzoxasilylstilbene compounds in organic solvents, plasticizers, resins, etc. increases dramatically compared to single compounds and mixtures of two or more types containing lower alkyl. However, based on this knowledge, we have succeeded in removing the limitations on the use and usage of bisbenzoxasilylstilbene compounds in whitening, and in particular, in preventing the occurrence of unevenness over time.

Conventionally, as a fluorescent brightener mixture, there is an invention described in Japanese Patent Publication No. 43-4202 aimed at increasing the brightness by 8 degrees, but the methyl group and butyl group, hydrogen and methyl group,
The solubility of bisbenzoxasilylstilbene compounds consisting of methyl and ethyl groups does not improve significantly in organic solvents, plasticizers, resins, etc. It is not possible to use a whitening method that uses a dissolved whitening agent, and there is no way to prevent the generation of mold after whitening. For example, in a single compound with 2 or less carbon atoms and a single compound with 3 or more carbon atoms, no matter how you change the alkyl group, the increase in solubility is within the range of 2 to 3 times at most; Even if one alkyl group of bisbenzoxasilyl has 3 or more carbon atoms and the other has 2 or less carbon atoms, the solubility is the same, It does not exhibit large solubility as disclosed in the present invention.

% or more, the present invention has a high solubility in the plasticizer, so the brightening agent does not harden over time, and an excellent whitening effect can be obtained immediately after whitening. and without causing spots after several weeks or months. In addition, when producing a brightened resin composition by dissolving a fluorescent brightener in a liquid or liquid initial polymer such as polystyrene, acrylic resin, or unsaturated polyester and then polymerizing it, Since the whitening agent is sufficiently dissolved, a resin composition containing it will not become partially yellowish, and a whitened resin composition can be obtained. Similarly, an excellent whitening resin composition can also be obtained by a method in which a fluorescent brightener is completely dissolved in a solution consisting of a polymer compound and an organic solvent, and then the organic solvent is removed to obtain a whitened polymer composition. can be obtained. Therefore, the present invention makes it possible to apply alkylbisbenzoxasilylstilbene-type fluorescent brighteners, which have strong brightening power and light fastness but could not be applied due to their low solubility, to a wide range of fields. The value above is extremely high.
