Abstract
A functional substance releasing agent is provided, comprising: a silicic acid ester of formula (I) wherein n is 2 to 50; wherein each R1 is independently selected from the group consisting of H, C1-22 alkyl groups, a —CNH2 group, a —R2CNH2 group, a —CNHR3 group, a —CNHR3 group and a —R2CNR3 group; wherein each R2 is independently a divalent group having 1 to 22 carbon atoms per molecule; and wherein each R3 is independently selected from a residual group from a functional molecule; wherein the functional molecule is selected from the group consisting of an aldehyde, a ketone and mixtures thereof.
