[0222] Hereinafter, the present invention will be described in more detail through examples and comparative examples, but the present invention is not limited to them, and appropriate changes can be implemented within the range that can be adapted to the above-mentioned and following gist, and they are all included in the technical scope of the present invention. Inside. In addition, "part" and "%" in a following Example and a comparative example mean a weight part or weight%.
[0223] In addition, the measurement and test in the following manufacture example, an Example, and a comparative example were performed as follows.
[0224] [1] Measurement of average particle diameter of polymer particles
[0225] The volume average particle diameter (Mv) of the polymer particle dispersed in the aqueous latex was measured using Microtrac UPA150 (made by Nikkiso Co., Ltd.). As a measurement sample, polymer particles diluted with deionized water were used.

manufacture example 1-1
[0264] Production Example 1-1: Preparation of Polybutadiene Rubber Latex (R-1)
[0265] Put 200 parts of deionized water, 0.03 parts of tripotassium phosphate, 0.25 parts of potassium dihydrogen phosphate, 0.002 parts of disodium ethylenediaminetetraacetic acid (EDTA), 0.001 parts of ferrous sulfate into the pressure-resistant polymerizer. Heptahydrate salt (Fe) and 0.15 parts of sodium dodecylbenzenesulfonate (SDS), while stirring, fully carry out nitrogen replacement and remove oxygen, then drop 100 parts of butadiene (BD) into the system, and heat up to 45°C. Putting in 0.015 pairs of Alkane hydroperoxide (PHP), followed by adding 0.04 parts of sodium formaldehyde sulfoxylate (SFS), to start polymerization. At 4 hours from the start of the polymerization, 0.3 part of SDS, 0.01 part of PHP, 0.0015 part of EDTA and 0.001 part of Fe were charged. Furthermore, 0.4 part of SDS was injected|thrown-in at the 7th hour from the start of polymerization. At the 10th hour of the p...
manufacture example 1-2
[0266] Production Example 1-2: Preparation of Organosiloxane Rubber Latex (R-2)
[0267]251 parts of deionized water, 1.8 parts of dodecylbenzenesulfonic acid, 100 parts of octamethylcyclotetrasiloxane, 2 parts of tetraethoxysilane, 2 parts of γ-acryloyloxypropane The mixed solution of oxydimethoxymethylsilane was stirred at 10000 rpm for 5 minutes with a homomixer to prepare latex. This latex was passed twice through a high-pressure homogenizer set at a pressure of 30 MPa. The obtained latex was stirred, and put all at once into a 5-port glass container equipped with a reflux cooler, a nitrogen blowing port, an additional port for monomers and emulsifiers, and a thermometer. The system was heated up to 80° C. over about 40 minutes while stirring, and then reacted at 80° C. for 6 hours. Thereafter, after cooling to 25° C. and leaving for 20 hours, the pH of the system was returned to 6.8 with sodium hydroxide to terminate the polymerization, and a latex containing organosilo...
