[0232] Synthetic examples, examples and comparative examples are given below by way of illustration, not by way of limitation. All parts and percentages are by weight unless otherwise indicated. The viscosity is measured at 25° C. according to JIS Z8803. Mw refers to the weight average molecular weight measured by gel permeation chromatography using polystyrene as a standard.
[0233] [(2-A) Surface-coated composite oxide nanoparticle dispersion]
[0234] Surface-coated composite oxide nanoparticle dispersions as shown below were used as UV shielding agents.
[0235] A-1: ZNTANB15wt%-E16 (2) from C.I.Kasei Co., Ltd (C.I.Kasei Co., Ltd) (add silicon dioxide to zinc oxide nanoparticles, and the zinc oxide nanoparticles are prepared by DC arc plasma method, Surface treatment with methyltrimethoxysilane and dispersed in alcohol mixture with the help of dispersant, particle concentration: 15%, particle size distribution measured by NanotracUPA-EX150 (Nikkiso Co., Ltd.): figure ...
Synthetic example 1
[0243] A 2-L flask was charged with 287 g (2.11 Si-mol) of methyltrimethoxysilane and cooled to a liquid temperature of approximately 10°C. After the flask is cooled, add 211g of SnowtexO (Nissan Chemical Co., Ltd., water-dispersed silica gel, average particle size 15-20nm, SiO2 content of 20%) and 93g of 0.25N acetic acid aqueous solution so that the internal temperature will not exceed 40°C , allowing hydrolysis to proceed. After the dropwise addition, the solution was stirred for 1 hour below 40° C., followed by 3 hours at 60° C. to allow complete hydrolysis.
[0244] Thereafter, 300 g of cyclohexanone was poured into the reaction mixture, heated under atmospheric pressure until the liquid temperature reached 92° C., thereby distilling off methanol produced by hydrolysis, and allowing condensation to proceed. 400 g of isopropanol diluent, 1.6 g of acetic acid and 1.6 g of 25% aqueous tetramethylammonium hydroxide (TMAH) were added to the reaction mixture. The mixture was ...
Synthetic example 2-9
[0247] Eight silicone resin coating compositions (II-b) to (II-i) were prepared as in Synthesis Example 1, except for the type and amount of the surface-coated composite oxide nanoparticle dispersion, and the amount of leveling agent have changed, as shown in Table 2.
