실험 절차
To 100 parts of an aqueous solution of pH 4.0 containing 5% of a styrene-maleic anhydride copolymer and a small amount of sodium hydroxide was added a mixed solution consisting of 10 parts of dodecyl gallate, 30 parts of a polyoxypropylene glycol monoether, 0.3 part of benzoin ethyl ether and 59.7 parts of an epoxy acrylate type photocurable resin (brand name: RIPOXY, manufactured by Showa Highpolymer Co., Ltd.), and they were emulsified. 10 parts of melamine, 25 parts of a 37% aqueous formaldehyde solution and 65 parts of water were adjusted to pH 9 with sodium hydroxide and then heated to 60° C. In 15 minutes, the mixture became transparent and a melamine-formaldehyde precondensate was obtained. This precondensate was added to the emulsion prepared previously. The resulting mixture was continuously stirred at 60° C. The formation of microcapsules was confirmed in 30 minutes and the microcapsule fluid was cooled to room temperature.
