Claim 1:
2. The additive according to claim 1, wherein the cationic polymerization initiator is a compound having a chemical structure of general formula (I):, wherein,
Y represents a single bond or CR85;
Z represents a single bond or CR86;
R72, R73, R75, R76, R77, R78, R85, and R86 are each independently selected from the group consisting of hydrogen atom, C1-6 alkyl, C1-6 alkoxy, C1-6 alkyl carbonyl, phenyl, and hydroxy, wherein the C1-6 alkyl, C1-6 alkoxy, C1-6 alkyl carbonyl and phenyl may further be substituted with one or two substituents selected from the group consisting of C1-6 alkyl, C1-6 alkoxy, C1-6 alkyl carbonyl, phenyl, and hydroxy;
R72 and R73 may further each independently represent adamantyl or C1-6 alkyl substituted with Si(OCH3)2(CH3);
or R75 and R76, or R77 and R78 may together form —(CH2)3-5—;
R81, R82, R83, and R84 are substituents selected from the group consisting of C1-4 alkyl, C1-4 alkyl carbonyl, and C1-3 alkoxy, wherein the C1-4 alkyl may be substituted with one C1-3 alkoxy group;
R71 and R74 are each independently a C1-3 alkyl group; and
Xf− is a counter anion.
