FIELD: microencapsulation technique. SUBSTANCE: invention relates to microencapsulation of organic solvents and solutions of coloration components, medical, and pharmaceutical preparations. Shell of microcapsule is formed from mutually penetrating lattices based on melamine-formaldehyde resin structured by ammonium salt of butyl acrylate/methacrylic acid copolymer and from hydrogel of polyvinyl alcohol cross-linked by orthoboric acid. EFFECT: facilitated microencapsulation procedure.
