A microchannel device, including a homogenization chamber, a deceleration-cooling channel, an acidity regulation channel, a microchannel reaction chamber, and an ultrafiltration desalination chamber. A method for preparing high-oil-load microcapsules using the aforementioned microchannel device, including: preparing an aqueous phase and an oil phase; feeding the aqueous phase and the oil phase to the homogenization chamber to form a first emulsion; cooling the first emulsion; adjusting pH of the first emulsion with dilute hydrochloric acid; feeding the first emulsion to the microchannel reaction chamber to form a second emulsion with a core-shell structure; removing Na.sup.+ and Cl.sup.− from the second emulsion; and subjecting the second emulsion to spray drying to obtain the high-oil-load microcapsule powder.

The wet adhesion of a coating composition may be improved through the use of voided latex particles as opacifying agents which contain a hollow interior as well as an outer shell of a polymer containing functional groups such as amino, 1,3-diketo, urea or ureido. Other types of functional groups may be introduced to the outer shell polymer in order to vary other desired characteristics of the coating. The voided latex particles are non-film-forming.
