キを発生する事が問題となつていた。High-grade paints such as automobile paints, pre-coat metal paints (hereinafter abbreviated as PCM), home appliances paints, general baking paints, etc. that are applied by industrial line painting have excellent anticorrosion performance as well as aesthetic appeal. A sophisticated finish is required. Therefore, it is indispensable for the finished coated surface to have a smooth appearance without cissing, craters, textures, or cloudiness. Actually, various surface modifiers such as a leveling agent, a defoaming agent, an anti-armpitting agent, a gloss-imparting agent, and an anti-cratering agent are used as additives for coatings to satisfy this performance. Conventionally, atomization coating such as spraying and high-speed continuous coating such as roll coater have been performed in line coating. In these coating methods, the mist of oil used in a compressor or roll coater machine or the mist of the paint itself may adhere to the object to be coated, which causes cissing due to these mist problems. I was told.

なる等の欠点がある。As an additive for solving the problem of cissing due to these external factors, its effect is exerted on conventional leveling agents, defoaming / leveling agents, defoaming agents, etc., whose main component is an acrylic polymer. Not recognized, but the effect is recognized only for additives containing silicone or its modified product as a main component. However, although this silicone-based additive is also excellent in cissing prevention effect against mist containing silicone oil, it has almost no effect on mist such as spindle oil, machine oil, and compressor oil. There is a defect that the mist of the added paint itself causes further cissing.
また、この種の添加剤はリコート性を害する欠点もある
ため、当業界ではこれらの欠点を解決し、ミストを原因

剤（表面調整剤）を提供することを目的とする。Further, since this kind of additive also has a drawback of impairing recoatability, in the art, an additive capable of solving these disadvantages, excellent in cissing resistance due to mist, and capable of improving leveling is strongly desired. It was Therefore, it is an object of the present invention to provide an anti-repellent agent (surface modifier) which prevents cissing due to mist and gives a smooth coating film.

Polymers having an average molecular weight of 1000 to 20000 obtained by polymerizing two or more of them have cissing prevention effect and smoothing effect by various mists, and have the disadvantages of the above-mentioned silicone additives. I found that not.

Alternatively, the average molecular weight obtained by polymerizing two or more thereof is 1,000 to 2,000.
0 polymers are provided. This polymer causes these external factors even when it is added to baking paint, especially automobile paint or PCM paint, even when the surface of the object to be coated is contaminated by oil, paint mist, polishing dust, etc. It is characterized by preventing repelling and improving smoothness, and does not cause deterioration of recoatability as seen in silicone additives.

る。The polymer can be produced by any of a bulk polymerization method by ionic polymerization and a solution polymerization method. As an example of a specific polymerization method, for example, in order to stop the polymerization after dropping the monomer in the presence of a polymerization initiator in a suitable solvent and reacting at −78 ° C. to 80 ° C. for 1 to 48 hours. A method of adding a polar solvent to stop the reaction is mentioned. As the solvent for the polymerization, for example, a solvent such as n-hexane, xylene, toluene, ethylene chloride, carbon tetrachloride or the like can be used.
Examples of the polymerization initiator include iodine, ZnCl 2 , SnCl 4 , Al
In addition to Cl 3 , BF 3 O (C 2 H 5 ) 2, etc., a Grignard reagent represented by the general formula RMgX (R is an alkyl group, X is a halogen group), an ionic polymerization initiator such as C 2 H 5 AlCl 2 is used. I can do things.

が本発明に於いて、特に好ましい。The polymer thus obtained has an average molecular weight of 1000 to 2000.
Must be in the 0 range. The reason is that when the average molecular weight is less than 1000, the effect of preventing cissing due to the external factor of interest is weak, and when the average molecular weight is 20,000 or more, the effect of preventing cissing due to the external factor of interest is obtained. Not only is this difficult, but the paint itself to which this is added is prone to cissing and craters, which is not desirable. Further, among these polymers, a polymer having an average molecular weight of 2000 to 8000 is particularly preferable in the present invention.

化塗膜にベタツキ等の弊害が生じるので好ましくない。The cissing inhibitor for external factors of the present invention is generally 0.01 to 2% by weight, preferably 0.05 to 0.5% by weight in the paint.
It is necessary to add it so that the concentration is less than this lower limit concentration, the desired effect is not observed when it is less than the lower limit concentration, while when it is more than the upper limit, cratering prevention effect is recognized, but stickiness etc. This is not preferable because it causes harmful effects.

併用が好ましい場合もある。Further, the cissing inhibitor due to the external factor of the present invention, even if adjusted or used in combination so as to be mixed and added with other surface modifiers and additives, the addition amount of the polymer is within the above range. As long as there is a desired cissing prevention effect, there is no problem. Especially when used in combination with a silicone compound, it is preferable to use it in combination with silicone because it has the effect of preventing cissing of oil mist, which is not effective with silicone compounds, and can further reduce the amount of silicone that impairs recoatability.
