DETAILED DESCRIPTION OF THE INVENTION

[0001]

2. Description of the Related Art Conventionally, as a method of forming a transparent colored coating film on the surface of a base material such as plastic, glass, and metal, there are known methods.
Generally, a dye is used as a coloring material, but the dye has poor weather resistance and is not suitable for outdoor use. On the other hand, paints using pigments have the disadvantages of being excellent in weather resistance, but having a large particle size of several tens of μm or more, and having low chroma and poor clarity and transparency due to irregular reflection.

[0003] Therefore, as described in JP-A-5-7830, a coating composition containing a finely dispersed pigment obtained by heat-melting and dispersing a specific pigment into primary particles is added. Thus, a design effect equivalent to that of the dye can be obtained, and a coating film having much better weather resistance than the dye can be formed. However, in this method, the finely dispersed primary particles are re-agglomerated, and the resin is fixed around the pigment. Therefore, in a thin film having a thickness of 20 μm or less, the coarse particles of the pigment partially protrude on the surface of the coating film, which is preferable in appearance. Absent.

Further, as described in JP-A-6-287488, a colored transparent coating film having excellent weather resistance is formed by blending a transparent iron oxide pigment with a color clear paint containing a dye. be able to.

However, these methods are all aimed at improving the transparency and the weather resistance, and the concealing property cannot be ensured with a thin film.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The colored coating material of the present invention comprises:
It is composed of a coloring material, an additive and a resin. The coloring material contains a dye and a pigment, and the additive contains a leveling agent and a dispersant.

As the dye, a dye soluble in a resin and an organic solvent can be used. Known dyes can be used as the dye. As the dye, for example, azo dye, anthraquinone dye, indigoid dye, phthalocyanine dye, diphenylmethane dye, triphenylmethane dye, xanthene dye, quinoline dye,
Perinone dyes and the like can be mentioned. Each of these dyes can be used alone or in combination of two or more. As the dye, an oil-soluble dye, for example, an azo-based, phthalocyanine-based or anthraquinone-based oil-soluble dye is more preferable because of its excellent compatibility with the resin.

The pigment has a particle size of 0.05 to 10 μm.
m, preferably from 0.1 to 3 μm, can be used. As the fine pigment, various pigments used for paints and inks can be used. Examples of the fine pigments include azo pigments, phthalocyanine pigments,
There are polycyclic pigments, etc., by changing the structure variously,
Characteristics such as color tone and durability can be changed.

Examples of the fine pigments include pigments used in coloring compositions for color filters, for example, Color Index Pigment Red (C.I.
tRed) 9, 97, 122, 149, 177, 215
Color Index Pigment Green 7, 36, etc.
Color Index Pigment Blue (CIPi
gment Blue) 15: 6, 22, 60, etc.
It is more preferable because it has excellent color tone and weather resistance, and further has a small average particle size and a narrow particle size distribution.

As the fine pigment, inorganic pigments such as barium sulfate, titanium oxide, red iron oxide, ultramarine, navy blue and carbon black can be used. One type of fine pigment can be used alone, or two or more types can be used in combination.

A fine pigment having a particle size of 0.05 to 10 μm, preferably 0.1 to 3 μm can form a coating film having excellent concealing properties and coloring properties even in a thin film.

The weight ratio of the dye to the fine pigment is 1:99 to 3
0:70, preferably 3:97 to 10:90. When the weight ratio of the dye is small, the sharpness tends to decrease, and when it is large, the weather resistance tends to decrease. The content of the coloring material can be appropriately changed according to the required color characteristics, but is from 5 to 80% by weight, and preferably from 10 to 40% by weight, from the viewpoint of coloring and hiding properties.

As the resin, a resin selected from the group consisting of an acrylic resin, a urethane resin, an epoxy resin, a silicone resin, a vinyl resin, a melamine resin and a polyester resin can be used without particular limitation.

Examples of the acrylic resin include homopolymers and copolymers of acrylic monomers (for example, acrylic acid, methacrylic acid, acrylic acid esters, methacrylic acid esters, etc.), acrylic monomers and other monomers. Copolymers with monomers (eg, acrylonitrile, styrene, etc.) can be used.

Examples of urethane resins include polyurethane acrylates and polyols (eg, polyester polyols and acrylic polyols) mainly composed of urethane and polyisocyanates (eg, methylene diisocyanate (MDI), tolylene diisocyanate (TDI), hexamethylene Diisocyanate (HM
DI), isophorone diisocyanate (IPDI), etc.).

As the epoxy resin, for example, a two-pack type epoxy resin which cures at room temperature using an amine containing a condensate of bisphenol A and epichlorohydrin as a curing agent, and a heat-curable epoxy resin used in combination with an amino resin or a phenol resin Epoxy resin or the like can be used.

As the silicone resin, for example, silicone-based silicone acrylate, a copolymer of methylphenyl silicone and silicone acrylate, a copolymer of methyl ethyl silicone and acrylate, and the like can be used.

As the vinyl resin, for example, polyvinyl chloride, polyvinyl acetate, polyvinyl chloride-vinyl acetate copolymer, polyvinyl butyral, polyvinyl alcohol and the like can be used.

As the melamine resin, for example, phenol-modified alkyd resin, amino alkyd resin, nitrocellulose alkyd resin, silicone alkyd resin and the like can be used.

As the polyester resin, for example, unsaturated polyester and the like can be used.

The content of the resin can be, for example, 95 to 40% by weight, preferably 90 to 50% by weight. When the content of the resin is small, the coating film tends to be cracked and peeled, and sufficient coating film strength tends not to be obtained. When it is large, the strength, abrasion resistance and concealing property tend to be inferior.

Examples of the leveling agent include a fluorine-based leveling agent, a silicone-based leveling agent (eg, methyl silicone oil, ethyl silicone oil, phenyl silicone oil, etc.), a polymer ether-based leveling agent, and a nonionic type containing halogen or a fluorine compound. A nonionic leveling agent such as a surfactant can be used, but a silicone leveling agent is particularly preferred from the viewpoint of uniform dispersibility.

The content of the leveling agent is, for example, 0.1.
When the content is from 01 to 29.9% by weight, preferably from 0.01 to 10% by weight, more preferably from 0.3 to 1% by weight, the leveling property of the colored coating material can be ensured, and the surface of the coated film is smooth. Can be formed. When the content of the leveling agent increases, the coating properties such as adhesion and hardness tend to decrease, and when it is too low, a smooth surface tends not to be obtained.

Examples of the dispersant include carboxylic acid surfactants (eg, non-silicone long chain carboxylic acid amine salts, carboxylic acids containing high boiling point ethers, etc.), nonionic surfactants, and hydrocarbon surfactants. , A cationic surfactant, an alkyl phosphate ester, a polyethylene glycol derivative, and a polyester polymer compound having an amino functional group in a molecule. Among them, a nonionic surfactant containing a fluorine compound can be used. Is preferable because the dispersibility and the flowability of the coating material are further improved.

The content of the dispersant is, for example, 0.01 to
It can be 29.9% by weight, preferably 0.01 to 10% by weight, more preferably 0.1 to 5% by weight. When the content of the dispersant is large, the film forming property tends to decrease, and the film strength tends to decrease. When the content is too small, secondary aggregation of the coloring material tends to occur, and the dispersing effect tends to decrease.

As an additive, for example, an anti-settling agent can be used in addition to the leveling agent and the dispersant. By using the anti-settling agent, the settling and floating of the pigment can be prevented, and the storage stability can be ensured. As the anti-settling agent, for example, an aliphatic polyamide-based anti-settling agent, a polyethylene oxide-based anti-settling agent, a polyacrylic acid-based anti-settling agent, a synthetic wax, an organic bentonite-based anti-settling agent, and ultrafine silica are used. Can be. By using the aliphatic polyamide-based anti-settling agent, the sedimentation and floating of the pigment can be prevented, and the storage stability of the paint can be ensured.

The content of the antisettling agent can be 0.01 to 30% by weight, preferably 0.01 to 10% by weight, more preferably 0.1 to 3% by weight. If the content of the antisettling agent is too large, the film strength tends to decrease, and if it is too small, the storage stability tends to decrease.

The colored coating material of the present invention is prepared by, for example, blending a pigment, a resin, and an additive, pulverizing the pigment using a pulverizer (eg, a sand grinder, an Ultra Viscomil, etc.), and dispersing each component. Thereafter, it can be produced by adding a dye and, if necessary, a resin to the obtained dispersion.

The grinding and dispersing are carried out, for example, by a grinder,
Particle size 1 mmφ or less, preferably 0.25 to 0.5 mmφ
About 85% of the medium.
If the particle size of the media is too large, sufficient pulverization tends to be impossible, and if it is too small, the impact force is small and dispersion tends to be impossible. Also, the disk peripheral speed is 5-10m
/ S, and it is preferable to repeat the number of passes 1 to 4 times. By using zirconia media, the amount of contamination can be reduced.

The colored coating material of the present invention is made of glass,
After coating on plastic, metal, etc. by spin coater, spray coating, etc.
By performing baking for a minute, a colored coating film can be formed.

Mie) (BM-1000) and an aliphatic polyamide-based anti-settling agent (W001 made by DEFRA) were added and dispersed with an Ultraviscomil to give a colored coating material.

The material composition ratio in the colored coating material was such that 40% by weight of a coloring material (dye and pigment), 1% by weight of an additive, and the remainder was a resin.

The colored coating material produced as described above was sprayed by spraying and dried at 120 ° C. for 30 minutes to form a coating film of about 10 μm. With respect to the obtained coating film, hiding properties, accelerated weather resistance, flatness, and coloring property were evaluated by the following methods.

The concealing property was determined by applying a 10 μm coating on each of a white coating film and a black coating film, drying the coated surface for a predetermined period of time, measuring the Y value of the coated surface, and concealing by the following formula. The rate was calculated. When the concealment ratio was 90% or more, the concealability was judged to be good. Hiding ratio = (Y value of coated surface on black coating film) / (Y value of coated surface on white coating film) × 100 The accelerated weather resistance was measured using a sunshine carbon arc lamp type weather resistance tester for 200 hours. I left it. The color difference (△ E) indicates how much the color changed compared to the initial sample after standing.
Was evaluated. When the color difference was 3.0 or less, no discoloration was observed, and it was judged as good.

As for the flatness, the surface roughness was measured by a surface roughness meter such as a stylus type, and those having a surface roughness smaller than 0.5 μm were evaluated as good, and the surface roughness was 0.5 to 2.0 μm. The sample having a surface roughness of greater than 2.0 μm was evaluated as poor, and the sample having a surface roughness larger than 2.0 μm was evaluated as poor. If it is Δ or more, it can be preferably used as a colored coating material.

The colorability was evaluated by using a pigment having a particle size of 10 μm and a color difference (ΔE) from a standard plate formed with a film thickness of 40 μm. When the color difference was 3.0 or less, no discoloration was observed, and it was judged to be good.
