To provide a bio-inactive encapsulated microcapsules having a thermal and mechanical stability, and a light resistance; and a wall membrane suitable for them.
Encapsulated microcapsules which encapsulate a core substance inside the space formed by the wall membranes and which has a wall membrane of an organopolysiloxane are produced by the direct polycondensation of one or several kinds of compounds (B) selected from among compounds (B) group given by the formula: RnSi(OH)mY(4-m-n) [wherein (m) is 1-4; (n) is 0-3; m+n≤4; R is an organic group, n-pieces of R can be the same or different; and (4-m-n) pieces of Y is at least one group selected from the group consisting of alkoxy, hydrogen, and siloxy] [among them, at least in one kind, m=2 or 3, and a compound (B) having at least one affinitive R to at least one of a continuous phase or a dispersed phase].
