| abstract | PURPOSE:To obtain uniform microcapsules by emulsifying a hydrophobic substance in an acidic aqueous solution in the presence of a specified anionic polymer electrolyte and then forming a condensation-polymerized wall membrane of an aminoplast pre-condensate. CONSTITUTION:A hydrophobic substance is emulsified in an acidic aqueous solution in the presence of an anionic polymer electrolyte essentially containing vinylpyrrolidone, alpha,beta-ethylenic unsaturated carboxylic acid, a monomer having phosphoric acid group, and/or a monomer having sulfonic acid group. Then, a condensation-polymerized wall membrane of an aminoplast pre-condensate is formed, so that microcapsules containing the hydrophobic substance in the insides are obtained. The aminoplast pre-condensate is preferably 10-100 pts.wt. per 100 pts.wt. of the hydrophobic substance to be contained in the microcapsules. Examples of the hydrophobic substance, include dyes for thermal recording paper, agricultural chemicals, medication, insecticides, etc. |
