• 22
• wherein each R3, R4 and R5 is independently an alkyl group, an alkenyl group, an alkynyl group, an aryl group or a heterocyclic group, provided that R5 includes a group represented by Formula (α):
• 23
• wherein Z is OR2, X, or OH;
• n is an integer of 1 to 3;
• each R1 and R2 is independently an alkyl group, an alkenyl group, an alkynyl group, an aryl group or a heterocyclic group;
• and X is a chlorine atom or a bromine atom,
• 24
• wherein Z2 is OR22, X2, or OH;
• n2 represents an integer of 1 to 3;
• each R21 and R22 is independently an alkyl group, an alkenyl group, an alkynyl group, an aryl group or a heterocyclic group, provided that R21 contains at least one primary amino group or at least two selected from the group consisting of primary and secondary amino groups;
• and X represents a chlorine atom or a bromine atom.
