。The polyethylene resin powder used in the present invention includes powder obtained by pulverizing the above-mentioned polyethylene resin by various pulverizing means, and powder produced by polymerization. The powder pulverized by the pulverizing means is, for example, the polyethylene resin and, if necessary, pigments, colorants, and other additives. After heating, melting and kneading using
Manufactured by pulverization methods such as frozen pulverization and room-temperature mechanical pulverization. In the case of chemical pulverization, the above-mentioned components are mixed in a solvent and then powdered to produce υ. - Powder produced by polymerization refers to powder produced directly by the above-mentioned suspension polymerization or gas phase polymerization. Powder may also be used. In particular, as the non-colored powder in the present invention, it is preferable to use the powder produced by the polymerization because it is economical due to the omission of the pulverization process, and the powder shape is spherical and has good powder coating properties. It is preferable in some respects. In addition, such powder is 100TL

。When a mixed powder made by simply blending powders of two or more colors is made into a coating film, each colored powder 2, 2 is mixed on the surface of the coating film as shown in Figure vX1.
′ fuses together and becomes opaque, so the powder inside the coating cannot be seen and the result is only a flat, mottled pattern, and the mottled pattern becomes dense, making it difficult to make beautiful windows. It is possible to mix more uncolored powder, especially powder with a haze value of 30% or less in a 50μ thick sheet, than the above-mentioned colored powders of two or more colors, Figure 2. The colored powder 2, 2' is floating in the uncolored resin powder 1, resulting in a coating film with a mottled pattern and a sense of depth. If the blending ratio of the resin composition in the present invention is within the above range, but the total amount of colored powders of two or more colors is large, the resulting coating film will have a planar pattern with poor sense of depth, which is undesirable. - If the total amount is less than the above range, the powders of two or more colors will become less noticeable, resulting in a state similar to that of a mere uncolored coating, which is not preferable.

た粉体を得た。On the other hand, 100 parts of the above polyethylene and 1.5 parts of titanium flour were melt-kneaded using an extruder to obtain white pellets. Similarly, red pellets were obtained from 100 parts of the above polyethylene and 1.5 parts of ultramarine red. Each of these colored pellets was mechanically crushed at room temperature, and the particle size was determined to be SOOμ.
A white and red colored powder was obtained which was very fine and had an average particle size of 200 μm.

ン系樹脂粉体組成物を得た。75 parts of the above uncolored powder, 10 parts of white powder, 15 parts of red powder and 0.8 part of finely ground dibenzylidene sorbitol were mixed using a Henschel mixer to obtain a bulk density of o, as y/CC, Angle of repose 37°, particle size 500μ
A polyethylene resin powder composition for powder coating with finer particles having an average particle size of 200 μm was obtained.
この粉体を用いて、実施例１と同様に流動浸漬を行なり
之が、塗膜は奥行き感のきわめて優れたまだら模様にな
シ美麗であった。Using this powder, fluid dipping was carried out in the same manner as in Example 1, and the coating film had a beautiful mottled pattern with an excellent sense of depth.

施例４の優秀さには及ばなかった。Comparative Example 3 Except for not mixing dibenzylidene sorbitol,
The same operation as in Example 4 was repeated. The resulting coating film gave a mottled pattern with a sense of depth, but the sense of depth was not as good as that of Example 4.
