摘要
The invention concerns microcapsules with aqueous core containing at least an oxidation-reduction enzyme selected among the oxidoreductases with 2 electrons, the oxidoreductases with 4 electrons and the peroxidases, and with a polymer coating consisting of at least a polymer selected among polycaprolactone, poly(3-hydroxybutyrate), poly(ethylene adipate), poly(butylene adipate), cellulose esters and at least a C1-C4 carboxylic acid, styrene and maleic anhydride copolymers, styrene and acrylic acid copolymers, styrene-ethylene/butylene-styrene block terpolymers, styrene-ethylene/propylene-styrene block terpolymers, and ethylene, vinyl acetate and maleic anhydride terpolymers. The invention also concerns a method for preparing said microcapsules and oxidation dyeing compositions containing same.
