Coating the protective layer, and then coating the coating composition of any one of items 1 to 4 . [Effect of the Invention] In the present invention, since the polyorganosiloxane of the component (B) is oriented on the surface layer of the coating film, 1275620 can form a coating film having high weather resistance, film forming property, water resistance, and freeze resistance. In the present invention, the component (B) is directly bonded to the oxime chain by the alkoxyalkyl group, and the indirect bonding of the sulfonium group to the sulfonium group is indirectly bonded to the oxime bond. Because of the non-branched chemical structure, it is not easy to affect the orientation of the coating film surface caused by steric obstacles. Further, the low polarity of the polyoxyalkylene and the difference in polarity of the component (A) promote the orientation on the surface of the coating film. Further, it is bonded to a moderately hydrophilic group, and can simultaneously have a smooth coating film having no coating film defects. Further, when the component (A) contains an alkoxyalkyl group, it reacts with the component (B), and the component (B) does not bleed out from the coating film over a period of time, and the weather resistance for a long period of time can be maintained. Therefore, the coating composition for a surface coating of the present invention is useful for the use of an exterior building material such as a building or a house, a roofing tile, or a building material such as an interior material, such as ceramic industrial building materials. [Embodiment] In the present invention, a conventionally known latex can be used as the copolymer latex (A), and is not particularly limited, and examples thereof include latexes such as acrylics, anthraquinones, polyamines, and fluorines, particularly from weather resistance and resistance. From the viewpoint of obstruction, etc., in the coexistence of water and an emulsifier, a latex obtained by emulsion polymerization of a polymerizable unsaturated monomer mixture in a multistage manner, a glass transition temperature of a copolymer of a central portion of the latex particles ( The TgA) is -40 to 35 t, preferably -30 to 20 ° C, and the copolymer of the outermost portion of the latex particles has a glass transition temperature (TgB) of 25 to 100 ° C, preferably 40 to 90 ° C. At °C, this TgB is at least 20 ° C higher than TgA, and more preferably a multilayered particulate latex having a height of 25 ° C or higher. 1275620 If the TgA is lower than -4 (TC, it is easy to block the coating film, if it is higher than 35 °C, its film forming property and low temperature physical property (freeze dissolution test) are less than ideal. Moreover, if TgB is lower than TgB At 25 °C, the formation of the coating film is prone to blockage. If it is higher than 100 °C, the film formation and low temperature physical properties (freeze dissolution test) are less than ideal, and if the TgB is not higher than TgA by at least 20 °C, Further, it is not preferable to have both an obstructive property and a film forming property to form a coating film, a low-temperature physical property (freeze dissolution test), etc. In the present specification, the glass transition temperature (°c) of the copolymer can be calculated according to the following formula. / Tg(°K) = (Wl / T1)+ (W2/T2) + *··

The multistage emulsion polymerization is carried out by subjecting a suitable mixture selected from the above polymerizable unsaturated monomers to a known emulsion polymerization as a first stage, and the obtained copolymer (corresponding to a core portion) is coexistent, in order The emulsion polymerization after the second stage is carried out. In the present invention, the above-mentioned multilayered particulate copolymer latex is a polymerizable unsaturated monomer containing 0 to 20% by weight of an alkoxyalkyl group-containing alkyl group, more preferably 0.1 to 15% by weight, 0%. 70% by weight of the cycloalkyl-containing polymerizable unsaturated monomer, preferably 0 to 50% by weight, 10 to 100% by weight, based on the other polymerizable unsaturated monomer, more preferably 35 to 99.9% by weight. In the coexistence of the acrylic copolymer (1) obtained by emulsion polymerization of the bulk mixture, a polymerizable unsaturated monomer having an alkoxyalkyl group content of from 〇20 to 1275620% by weight is added, preferably 0.1 to 15% by weight, 0~. 70% by weight of a cycloalkyl-containing polymerizable unsaturated monomer, more preferably 0 to 50% by weight, and 10 to 100% by weight of other polymerizable unsaturated monomer, more preferably 3 5 to 9 9 · 9 by weight The core/shell latex of the acrylic copolymer (ii) obtained by emulsion polymerization of the monomer mixture of the % composition is particularly preferable from the viewpoints of weather resistance, water resistance, and freeze resistance of the obtained coating film. In the core/shell emulsion described above, the alkoxyalkyl group-containing polymerizable unsaturated monomer is polymerized in both the core portion and the shell portion, and is preferably considered from the viewpoints of weather resistance and temperature resistance of the obtained coating film. Further, from the viewpoint of the balance between the reactivity and the storage property of the coating material, the alkoxy group of the alkoxyalkyl group-containing polymerizable unsaturated monomer is particularly preferably an ethoxy group. When the alkoxy group is a methoxy group, the storage property of the coating is poor due to a rapid condensation reaction. On the other hand, when the number of carbon atoms is more than a propoxy group, the effect of improving the weather resistance is not significant because the condensation reaction is slow. ideal. From the viewpoint of weather resistance, in the core/shell emulsion described above, the cycloalkyl group-containing polymerizable unsaturated monomer is preferably copolymerized in the shell portion, preferably in the above-mentioned core/shell portion. In the latex, the weight ratio of the core portion to the shell portion is 1 〇/90 to 90/10, preferably 20/80 to 80/20. If it is out of this range, the core portion will be less likely to cause film formation of the coating film to be lowered, and if the core portion is large, the anti-blocking property of the coating film is not preferable. The above-mentioned copolymer latex (A) is used as an emulsifier for emulsion polymerization, and may be, for example, sodium dialkyl sulfosuccinate, sodium dodecylbenzenesulfonate, sodium lauryl sulfate or polyepoxy resin depending on desired characteristics. Anionic emulsifiers such as sodium alkyl phenyl ether ether and sodium alkyl diphenyl ether disulfonate; non-ethylene oxide higher alcohol-12-1275620 ether and polyethylene oxide alkyl phenyl ether An ionic emulsifier, or an anionic or cationic reactive emulsifier containing a radically polymerizable double bond. When the above copolymer latex (A) is subjected to emulsion polymerization, it is particularly preferable to use an anionic reactive emulsifier such as a radical polymerization of a (meth)allyl group, a propenyl group or a butenyl group. Sodium sulfonate and sodium sulfonate amine salt of a polyunsaturated group and a polyalkylene oxide group, such as "Fujimu" (trade name, Kao (share) system), "Ermumir" (trade name) , Sanyo Chemical (share) system, "Children's Dragon" (trade name, first industrial pharmaceutical (share) system). In the above emulsion polymerization, it is preferred to carry out emulsion polymerization using a polymerization initiator in the presence of water and the above emulsifier, and a chain transfer agent such as a mercaptan may be used as needed. A polymerization initiator which can be used, for example, potassium peroxysulfate, sodium peroxodisulfate, ammonium peroxosulfate, azobiscyanovaleric acid, 2,2'-azobis[2-methyl(2-hydroxyethyl)di An organic azo compound such as ethyl ketone oxime, an organic peroxide such as benzoquinone or ditributyl hydroxy peroxide, or the like, which is obtained according to the above-mentioned copolymer latex (A). The average particle diameter is in the range of 0·02 〜0·5 μιη, 〇·1 〇 3·3 μιη. The polyorganosiloxane (Β) of the present invention is a polyoxyalkylene compound which is present in the surface layer after the coating film is formed, and is a polyoxyalkylene compound which is present in the surface layer after the formation of the coating film. Usually, the polyorganosiloxane is blended at the time of coating. In the above general formula, R1 and R2 are the same or different methyl or methoxy groups such as methoxy or ethoxy groups, and particularly preferably a methyl group. In the above general formula, R3 is an alkyl group having 1 to 4 carbon atoms or a glycidyl group. Alkyl groups such as methyl, ethyl, propyl, butyl and the like. Among them, at least one selected from the group consisting of ethyl, propyl, epoxypropyl and the like is preferable from the viewpoint of the storage stability of the coating material -13 - 1275620. In the above general formula, R4 is a R5(0 R6)n(〇R7)m〇Z (R5 is an alkylene group having 1 to 4 carbon atoms, R6 and R7 are an alkylene group having 2 to 4 carbon atoms, and Z is A hydrogen atom, an alkyl group or an acetate group, ❿ is 1,000~1,000, η is 0 to 1,000, and m + n22 . Further, m + n is 2 to 2,000, and 2 to 500 is more appropriate. Further, p is preferably 1 to 1,000, preferably 1 to 300, q is 1 to 1, and more preferably 1 to 300. If the P exceeds 1,000, the storage stability of the coating is low, and if it is less than 1, the coating film produced is less likely to be cracked. Further, if q exceeds 1, the storage stability of the coating is low, and if the coating is less than 1, the coating film is less likely to be cracked. The above polyorganosiloxane (B) has a weight average molecular weight of from 500 to 30,000, more preferably from 1,000 to 10,000. If the average molecular weight of the polymerization is less than 500, the storage stability of the coating is low. On the other hand, if it exceeds 30,000, it is difficult to localize the surface layer of the coating film, and the effect of improving the weather resistance of the coating film is not so remarkable. The weight average molecular weight is obtained by converting the molecular weight measured by colloidal chromatography based on the molecular weight of polystyrene. In the present invention, the amount of the above component (B) is from 〇·ΐ to 50 parts by weight, preferably from 0.5 to 30 parts by weight (solid content), relative to 100 parts by weight of the copolymer latex (A) (solid content). . If the amount is less than 0.1 part by weight, the effect of enhancing the weather resistance is not good, and if it exceeds 50 parts by weight, the film formability is liable to occur, and the storage stability of the coating is lowered. -14- 1275620 The method of adding the above-mentioned component (B) to a water-based paint is a method of directly adding and forcibly stirring and mixing, or dispersing water by using an emulsifier, but the method of the former is considered to be advantageous from the viewpoint of enhancing weather resistance. . In the coating composition for a surface coating of the present invention, a pigment such as a water-soluble or water-dispersible resin, a coloring pigment, and an extender pigment other than the above component (A), a dispersing agent, an organic solvent, and a pH may be appropriately blended as needed.

The specular reflectance is used as the initial gloss 値 (as the test start time of the gloss maintenance rate, that is, zero time). Then, using a daylight type aging tester (manufactured by Sijia Tester Co., Ltd.), an improved weather resistance test (rain cycle; 12 minutes/hour, black control panel temperature of 60 to 66 ° C) was carried out. 60 ° - 60 ° specular reflection after the test time of 500 hours was measured. -20 - 1275620 rate was used as the final gloss 値, and this enthalpy was divided by the initial gloss 値, and the enthalpy was calculated as the gloss retention. ◎: gloss retention rate is greater than 80%, no appearance change 〇: gloss retention rate is greater than 79~70%, no appearance change △: gloss retention is 69~50%, slightly discolored X: gloss retention is less than 50%, obvious discoloration (*2) Anti-blocking property: Two test panels were prepared in the same manner as in the above (*1). The two coating surfaces were brought into contact with each other, and an obstructive tester was applied at 40 ° C, and a weight of 1 kg/cm 2 was applied for 1 to 20 minutes to visually evaluate the appearance change of the coating film. 〇: No change △: Traces of slight resistance to residue X: Adhesion of the coating film cannot be separated (*3) Film-forming property: Using a thin coater ι〇〇μηη, on a glass plate (7 0 X 1 5 0 X 4 Mm) Each of the water-based paints of the upper coating examples and the comparative examples was dried in a constant temperature chamber at 5 ° C for 24 hours to prepare test test sheets for evaluation of film formation. The coating film of the test plate was placed under a magnifying lens of 10 times to observe the surface, and the state of the crack was evaluated. 〇: no cracks △: some cracks appear in part X: all cracks appear (* 4) Frost resistance: The same test method as above (* 1 ), the test panels prepared in the air are placed in the air at -2 The state of the coating film was evaluated by freezing at 0 °C for 2 hours and melting for 1 hour in 20 t of water for one cycle, and after each test plate was subjected to 300 cycles of the test -21 - 1275620. 〇: no cracks △: slight cracks appear in part X: all cracks appear [Table 3]
