原因となっていた。[Prior art] Acrylic fibers have excellent dyeing clarity, light resistance,
In terms of bulkiness, it has superior properties not found in polyamide and polyester fibers, which are general-purpose clothing fibers, so it is widely used for clothing and interior decoration such as curtains and mats. However, in applications such as curtains and parasols that require light resistance, those colored using basic dyes, disperse dyes, and acid dyes have the disadvantage of poor light resistance. In order to improve the above-mentioned drawbacks, a method is known in which a pigment solution containing an acrylonitrile polymer or a surface-treated pigment is dispersed in a solvent, filtered, and then added to the dope (for example, JP-A-61 -6701
Publication No. 4). However, although pigments added to the spinning stock solution can be spun without coarse particles immediately after dispersion, depending on the type of pigment, they aggregate and settle within a few hours or days, and the aggregates clog the filter of the spinning nozzle, causing pressure This causes problems during spinning, such as the inability to spin and yarn breakage.

る。尚例中の部および%はすべて重量基準である。[0007] The liquid colorant of the present invention contains 0.5 to 150 parts by weight of the pigment per 100 parts by weight of the liquid dispersion medium, and if the amount of pigment exceeds 150 parts by weight, the viscosity of the liquid colorant increases. As a result, the supply performance by the quantitative feeder deteriorates, which is not preferable. In order to obtain the liquid colorant of the present invention, a predetermined amount of pigment and a liquid dispersion medium are blended and mixed using a mixer such as a homo mixer or a disper mill, and then kneaded using a general kneader such as a 3-roll or sand mill. to disperse the pigment. The viscosity of the obtained liquid colorant is preferably 10 to 300 poise at 25°C (BM type rotational viscosity, rotor No. 4, 20 rpm). The liquid colorant of the present invention can be used for acrylic fibers spun from a dimethylcarbamyl solution of an acrylic resin. The amount of liquid colorant added is 0.00 parts per 100 parts of solid content of the acrylic resin.
1 to 15 parts by weight is preferred. Examples will be explained below. All parts and percentages in the examples are based on weight.

After stirring in a dissolver for 10 minutes, the mixture was passed through a 15-liter horizontal sand mill three times to obtain a liquid colorant with coarse particles of 25 μm or less and a viscosity of 2.8 poise/25° C. Immediately after filtering this liquid colorant with a 5μ cartridge filter, 10 parts of this liquid colorant was added and dissolved in 100 parts of the acrylonitrile solution used in Example 1 using a quantitative feeder, and the same procedure as in Example 1 was carried out. This was spun to obtain 1.5 denier acrylic fiber. Table 1 shows the results of the short fibers obtained.

る。[Effects of the Invention] The liquid colorant for molded acrylic resin of the present invention uses a liquid dispersion medium with excellent pigment dispersibility, so it has excellent pigment dispersibility and dispersion stability. Therefore, it can be used as a coloring agent for base material, especially added to a dimethylcarbamyl-based solution of an acrylic resin, and a resin molded article with excellent coloring power can be obtained. Furthermore, when used as a coloring agent for acrylic fibers, it is possible to produce acrylic fibers with excellent appearance without adversely affecting spinnability, drawability, etc.
