〈産業上の利用分野〉
本発明は、着色顔料を含む、紫外線硬化可能
で、かつ厚膜で耐摩耗性等の優れた塗膜が得られ
る紫外線硬化型被覆組成物に関するものである。
〈従来の技術〉
近年、無公害、省資源などの社会的要請に伴
い、無溶剤もしくは、有機溶剤量の少ない紫外線
硬化型被覆組成物が、一部採用される傾向にあ
る。しかしながら、従来の紫外線硬化型被覆組成
物は、着色顔料を含まないクリヤーが主流であ
り、着色顔料を含むエナメルは、厚膜化出来ない
ため一部で実用化されているにすぎず、伸び悩み
の状況にある。
前述の如く、着色顔料を含有する紫外線硬化型
被覆組成物は、厚膜にすると紫外線が塗膜内部に
十分透過せず、そのため硬化不良を起し、塗膜膜
表面のみの硬化で、シワが生じたりして塗膜外観
が悪く、また塗膜膜性能も悪いものであつた。
そこで、着色顔料として紫外線を吸収しにくい
顔料を使用する方法、高反応性の紫外線重合性化
合物や光増感剤を使用する方法、紫外線ランプと
して長波長サイドの光線を発するランプを使用す
る方法等が提案されているが、いずれも膜厚が
30μ程度が限界であり、それ以上になると硬化不
良を起したり、また着色力、隠蔽力も通常のエナ
メルに比較し劣るものであつた。
〈発明が解決しようとする問題点〉
本発明は、以上の如き現状に鑑み、厚膜化出来
かつ耐摩耗性、耐衝撃性、耐スリ傷性、難燃性、
遮音性、密着性等の優れた塗膜が得られる紫外線
硬化型被覆組成物を提供することを目的とするも
のである。
〈問題点を解決するための手段〉
すなわち本発明は、
着色顔料を含有する紫外線硬化型被覆組成物に

かつ中心粒径100μ以下の透明な球状ガラスビー
ズを全被覆組成物固形分中に20〜80重量％含有せ
しめること
を特徴とする紫外線硬化型被覆組成物に関する。
本発明の紫外線硬化型被覆組成物は、着色顔料を
含有せしめているにもかかわらず、特定のガラス
ビーズを含有せしめたことにより、光エネルギー
が塗膜内部に伝播されそれ故、数百μというオー
ダーまで厚膜化しても、塗膜深部においても十分
硬化し、また従来の紫外線硬化型被覆組成物では
得られなかつた塗膜強度、耐摩耗性、難燃性等の
優れた塗膜が得られるという特徴を有しているも
のである。本発明においてガラスビーズを除く、
紫外線硬化型被覆組成物は、従来から通常使用さ
れているものが特に制限なく使用出来る。すなわ
ち本発明における紫外線硬化型被覆組成物は、紫
外線重合性化合物、光開始剤を必須成分とし、さ

るものである。
さらに詳しく説明すると、前記「紫外線重合性
化合物」としては、分子内にラジカル重合可能な
不飽和二重結合を有する化合物が用いられる。具

<Industrial Field of Application> The present invention relates to an ultraviolet curable coating composition containing a colored pigment, which can be cured by ultraviolet rays, and provides a thick coating film with excellent abrasion resistance. <Prior Art> In recent years, due to social demands such as non-pollution and resource saving, there has been a tendency to partially adopt ultraviolet curable coating compositions that are solvent-free or contain a small amount of organic solvent. However, the mainstream of conventional UV-curable coating compositions is clear, which does not contain colored pigments, and enamels containing colored pigments have only been put into practical use in some areas because they cannot be made into thick films. situation. As mentioned above, when an ultraviolet curable coating composition containing a colored pigment is formed into a thick film, the ultraviolet rays do not penetrate sufficiently into the coating, resulting in poor curing, and only the surface of the coating is cured, causing wrinkles. The appearance of the coating film was poor, and the performance of the coating film was also poor. Therefore, methods include using pigments that do not easily absorb ultraviolet rays as coloring pigments, using highly reactive ultraviolet polymerizable compounds and photosensitizers, and using lamps that emit light on the long wavelength side as ultraviolet lamps. have been proposed, but in both cases the film thickness is
The limit is about 30μ, and if it exceeds this, curing failure occurs, and the coloring power and hiding power are inferior to that of ordinary enamel. <Problems to be Solved by the Invention> In view of the above-mentioned current situation, the present invention has been developed to provide a film that can be thickened and has wear resistance, impact resistance, scratch resistance, flame retardancy,
The object of the present invention is to provide an ultraviolet curable coating composition that provides a coating film with excellent sound insulation and adhesion properties. <Means for Solving the Problems> In other words, the present invention provides an ultraviolet curable coating composition containing a colored pigment, in which the difference in refractive index between the ultraviolet curable coating composition excluding the colored pigment and the clear coating film is Within 0.3,
The present invention also relates to an ultraviolet curable coating composition, characterized in that the total solid content of the coating composition contains 20 to 80% by weight of transparent spherical glass beads having a center particle diameter of 100 μm or less.
Although the ultraviolet curable coating composition of the present invention contains a colored pigment, the inclusion of specific glass beads allows light energy to be propagated inside the coating film. Even when the film is made to be as thick as the order of magnitude, it is sufficiently cured even in the deep part of the film, and provides a film with excellent film strength, abrasion resistance, flame retardance, etc. that cannot be obtained with conventional UV-curable coating compositions. It has the characteristic of being In the present invention, excluding glass beads,
As the ultraviolet curable coating composition, any conventionally used coating composition can be used without particular limitation. That is, the ultraviolet curable coating composition of the present invention contains an ultraviolet polymerizable compound and a photoinitiator as essential components, and further contains extender pigments, solvents, additives, etc. as necessary. To explain in more detail, as the "ultraviolet polymerizable compound", a compound having an unsaturated double bond capable of radical polymerization in the molecule is used. Specifically, relatively low molecular weight polyester resin,
Alkyd resin, polyether resin, acrylic resin, epoxy resin, urethane resin, silicone resin, polybutadiene resin, acrylic oligomer or prepolymer, and 2-ethylhexyl (meth)acrylate, 2-hydroxyethyl (meth)
Acrylate, tetrahydrofurfuryl (meth)
Acrylate, dipropylene glycol mono(meth)acrylate, (meth)acrylamide, N
Typical examples include reactive monomers such as vinylpyrrolidone, triethylene glycol di(meth)acrylate, trimethylolpropane tri(meth)acrylate, and dipentaerythritol hexa(meth)acrylate, alone or in mixtures. Further, as ultraviolet polymerizable compounds, cationic ring-opening polymerizable vinyl-2-ethylhexyl ether, vinyldecyl ether, 1,2-epoxycycloxane, dicyclopentadiene dioxide, sorbitol polyglycidyl ether, etc. can be used. Examples of the "photoinitiator" include carbonyl compounds such as benzoin, benzophenone or their esters, benzoyl peroxide, azobisisobutyronitrile, diphenyl disulfide, N-methyldiethanolamine, 2,5
Typical examples include -diethoxy-4-(p-littlethio)benzenediazonium hexafluorophosphate. Typical extender pigments include silica sand, silicates, talc, kaolin, barium sulfate, calcium carbonate, glass in powder, flake, and fiber shapes, and resin powders such as polyurethane, polyester, polyethylene, and polystyrene. It will be done. Furthermore, typical examples of the "solvent" include toluene, xylene, acetone, methyl ethyl ketone, ethyl acetate, and the like. The ultraviolet curable coating composition of the present invention is a clear composition having the above composition, mixed with a colored pigment and glass beads. As the coloring pigment, ordinary inorganic and organic dyes and pigments can be used. Specifically, titanium oxide, zinc sulfide, zinc white, lead white, lithopone, carbon black, oil smoke, dark blue, phthalocyanine blue, gun blue,
Carmine FB, yellow lead, zinc yellow, Hansa yellow,
Typical examples include ocher, red iron oxide, and insoluble metal-containing azo dyes. In particular, in the present invention, zinc sulfide, oil smoke,
Suitable dyes include Gunsei, phthalocyanine blue, carmine FB, yellow lead, ocher, red iron, and insoluble metal-containing azo dyes. In the present invention, glass beads are used as described above. Such glass beads must have the ability to propagate light energy into the coating film, and therefore must satisfy the following conditions. (a) The center particle size is 100μ or less, preferably 10 to 60μ. If the center particle size exceeds 100 μm, the coating film curing properties are not affected, or the glass beads become noticeable in the resulting coating film, resulting in roughness and the like, which is unfavorable in terms of coating film appearance. In addition, a decrease in physical properties such as tensile strength is observed. On the other hand, the lower limit of the particle size is not particularly limited, but it is set within the above range since the transmittance tends to decrease substantially. (b) Transparent and spherical. Note that the spherical glass beads function as lenses and have the effect of increasing transmittance. Other shapes are not suitable because they tend to cause diffused reflection, and the light energy that causes retroreflection and hardens the coating is significantly attenuated in the deep part of the coating. (c) The refractive index of the glass beads is within 0.3 of the refractive index of the clear coating film of the ultraviolet curable coating composition excluding colored pigments. It should be noted that if the difference in refractive index exceeds 0.3, the light energy for curing the coating film will be significantly attenuated in the deep part of the coating film when the film is thickened, which is not suitable, as this will result in poor curing. The glass beads used in the present invention can be used without particular limitations as long as they satisfy the above conditions. Usually, the refractive index N D of a clear coating film of an ultraviolet curable coating composition is about 1.4 to 1.6 . Glass, potash/lead glass, potash/soda/lead glass, borosilicate glass,
Specific examples include high alumina glass and potash/soda/barium glass, but it is obvious that the glass is not limited to these. The ultraviolet curable coating composition of the present invention consists of the above-mentioned components, and the proportion of glass beads is 20 to 80% by weight, particularly preferably 30 to 70% by weight, based on the solid content of the total coating composition. The ultraviolet polymerizable compound is 10 to 60% by weight, particularly preferably 20 to 50% by weight,
The content of the colored pigment is 40% by weight or less, and the lower limit is arbitrarily determined depending on the hiding power and coloring power desired for the resulting coating film. In addition, if the number of glass beads is less than the above range,
The propagation of light energy by the glass beads in the coating film becomes poor, resulting in poor curing of the coating film, and conversely, if it is too large, the physical strength of the coating film deteriorates, which is not preferable. In addition, if the amount of the UV polymerizable compound is less than the above range, the physical strength of the coating film will deteriorate, and if it is too much, the amount of glass beads will be relatively reduced when the color pigment is used, resulting in poor curing of the coating film. Undesirable. Furthermore, if the amount of coloring pigment is more than the above-mentioned range, the amount of glass beads will be relatively reduced and the coating film will tend to be poorly cured, and even if a large amount is added, the hiding power and coloring power of the coating film will not improve much. The ultraviolet curable coating composition of the present invention is coated or printed on a coated substrate using a conventional coating means or printing means, and then irradiated with ultraviolet rays to induce a photopolymerization reaction and cure the coating film. Note that as a light source used for irradiating ultraviolet rays, a low pressure mercury lamp, a high pressure mercury lamp, a metal halide lamp, a carbon arc lamp, a xenon lamp, a chemical lamp, etc. are used. Furthermore, the coating can be applied to various base materials such as metal, wood, plastic, gas, ceramics, concrete, and paper. In particular, since a coating film excellent in abrasion resistance, impact resistance, scratch resistance, flame retardance, and sound insulation performance can be obtained, it can be suitably used for architectural interiors. <Effects of the Invention> Since the ultraviolet curable coating composition of the present invention contains specific glass beads, it has a coating composition of several hundred microns (e.g.
Even a film as thick as 500 μ) can be sufficiently cured by UV irradiation, and can be made thicker, providing coatings with hiding and coloring power, which is revolutionary in practical terms. It is. In addition, since glass beads are mixed, the resulting coating film has abrasion resistance, impact resistance, scratch resistance, flame retardancy,
It has excellent sound insulation and adhesion properties, and it also does not easily generate heat when irradiated with ultraviolet rays, so it can be applied to heat-sensitive substrates, and it also has the characteristics of preventing wrinkles in the coating film due to heat. I have it. The present invention will be explained below using examples. In the examples, "parts" and "%" are expressed on a weight basis.
