Description

The present invention relates to heterocyclic compounds, their production and a process for dyeing or printing hydrophobic fiber materials therewith. More particularly, the present invention relates to benzodifuranone compounds useful for dyeing or printing hydrophobic fiber materials, for example, those such as polyester fibers and fiber materials containing the same, in a blue color.

Disperse dyes useful for dyeing or printing hydrophobic fiber materials have been increasingly desired to have much superior dyeability and capability of giving dyed or printed products excellent in various fastness properties with consumers' trend toward higher grade clothings. Answering such trend to increase the added value of dyed or printed products of hydrophobic fibers or hydrophobic fiber containing fiber materials, they are often subjected to various after-finish treatments such as softening finish, antistatic finish, feel-improving finish and the like. However, these after-finish treatments usually carried out at relatively high temperatures encounter problems of dye bleed, so that the dyed or printed products deteriorate in their wet fastness properties, particularly those such as washing fastness.

So far, many attempts to develop a blue disperse dye capable of giving dyed or printed products excellent in washing fastness have been directed mainly toward azo compounds, so that many azo compounds have been proposed therefor. However, those known azo compounds are not yet sufficient to solve the problem such that the washing fastness of dyed or printed products becomes markedly poor after the finish treatments.

There are other attempts to develop benzodifuranone compounds useful for dyeing or printing hydrophobic fiber materials, as disclosed in, for example, JP-A-52-109526 and 2-151663. However, the benzodifuranone compounds are also insufficient to satisfy both the dyeability and the fastness properties at the same time, and still awaiting for improvements.

It is the object of the present invention to provide disperse dye compounds having excellent dye properties for dyeing or printing hydrophobic fiber materials, particularly those such as polyester fiber materials, and capable of giving dyed or printed products bright in color and excellent in fastness properties such as light fastness, sublimation fastness and wet fastness, particularly those such as washing fastness.

The compounds of the formula (I) are useful for dyeing or printing hydrophobic fiber materials, particularly those such as polyester fiber matereils. In utilizing the present heterocyclic compound in such field, the compounds (I) can be finely pulverized in an aqueous medium together with a suitable dispersant such as naphthalenesulfonic acid/formaldehyde condensate, lignin sulfonic acid or the like, thereby obtaining a liquid dye dispersion. The liquid dye dispersion can be used as it is for the dyeing or printing of fiber materials, or dried with, for example, a spray drier to be made in a powder form.

Dyeing can be carried out by a high temperature dyeing method wherein hydrophobic fiber materials are dipped in an aqueous dye bath and heated to a temperature of 105.degree. C. or higher, preferably 110.degree. to 140.degree. C. under increased pressures, a carrier dyeing method wherein dyeing is carried out in the presence of a carrier such as o-phenylphenol, trichlorobenzene or the like at a relatively high temperature, for example, water-boiling temperature, or a thermosol method wherein the fiber materials are padded with an aqueous dye dispersion and dry-heated at a temperature of 150.degree. to 230.degree. C. for 30 to 60 seconds.

Printing can be carried out by mixing the aqueous dye dispersion with a suitable stock paste to obtain a color paste, padding fiber materials with the color paste and then steaming or thermosol-treatment.

In addition, the fiber materials can also be dyed by a solvent dyeing method wherein an organic solvent such as trichloroethylene, perchloroethylene or the like is used as a dyeing medium. The dyed or printed products thus obtained can be subjected, if desired, to after-finish treatments such as softening finish, water-repelling finish, feel-improving finish, antistatic finish and sanitary finish in a conventional manner. The various fastness properties, especially washing fastness do not deteriorate even after the after-finish treatments.

The present heterocyclic compounds of the formula (I) can be characterized by the facts such that hydrophobic fiber materials, particularly those such as polyester fiber materials, can be dyed or printed in a usual manner using the present compound (I), thereby obtaining dyed or printed products of a brilliant blue color excellent in various fastness properties such as light fastness, sublimation fastness and wet fastness and such fastness properties do not deteriorate even after heat-set treatment and after-finish treatments.

The present heterocyclic compounds of the formula (I) can be characterized also by superior dyeability, so that dyed or printed products of a deep color without unevenness of dyeing can be readily obtained, with superior build-up property and superior dye bath stability (low pH sensitivity).

In consideration of the characteristic features described above, the heterocyclic compounds of the present invention can be advantageously used particularly for the dyeing of apparels such as sportswear, which are required to be dyed usually in a deep color and to have superior washing fastness because they are to be washed again and again. Moreover, a compound of the present invention can be used in combination with other dyes to improve the dye performance and to obtain a variety of color.

The present invention is illustrated in more detail with reference to the following Examples, which are only illustrative but not limitative for the scope of the present invention. In the Examples, part and % are by weight.

EXAMPLE 1

The resulting dye dispersion was dried to form powder. Polyester cloth (10 parts, Tetron jersey, a product of Teijin Limited, in Japan) was dipped in a dyebath containing the powder (0.6 part), and dyeing was carried out for 60 minutes at 130.degree. to 135.degree. C. under increased pressures. The dyed cloth was subjected to reduction-rinsing treatment at 85.degree. C. for 10 minutes in a solution of sodium hydroxide (3 parts), hydrosulfite (3 parts) and a betaine amphoteric surfactant (3 parts) in water (3000 parts), washed with water and then dried, thereby obtaining a dyed product of a brilliant blue color superior in light fastness, sublimation fastness and wet fastness.

The resulting dyed product was subjected to softening and anti-static finishing by the following method.

The dyed product was dipped in a padding liquor containing a soft-finishing agent (10 g/l, Sumitex Softener LK-1, a product of Sumitomo Chemical Co., Ltd., in Japan) and an anti-static agent (5 g/l, Sumistat F-1, a product of Sumitomo Chemical Co., Ltd., in Japan), squeezed uniformly at a pick-up of 80%, again dipped in the same padding liquor as above, squeezed at the same level as above, pre-dried at 80.degree.

The thus after-finished dyed product was found to have a superior washing fastness.

EXAMPLE 3

The compound of the formula (I) obtained in Example 1 (1.3 part) was finely pulverized with the aid of lignin sulfonic acid (3.7 parts). To the resulting dispersion were added hot water (35 parts) and a half emulsion paste (60 parts) having the following composition.

C. for 6 hours and thereafter, ammonium persulfate (2.34 parts) was added to the reaction mixture. The resulting mixture was kept at 100.degree. C. for additional 1 hour. The reaction mixture was cooled to room temperature and thereafter, the procedure of Example 1 was repeated to obtain a compound of the following formula (2). ##STR25## The solution of this compound in DMF had a greenish blue color.
