Polyisocyanate composition

A polyisocyanate composition, comprising isocyanurate having a structure A and isocyanurate having a structure B,

• wherein the structure A is:
• R′1, R′2 and R′3 are respectively selected from the following four structures, wherein at least one of R′1, R′2 and R′3 is selected from a structure (I) or a structure (II):
• one, two, or three group(s) among R1, R2, R3, R4, R5, R6 and R7 in the above structural formulae is/are CH3, and the rest are hydrogen;
• the structure B is
• Z1, Z2 and Z3 may be any one or both of the following two structures:
• and
• a molar ratio of the isocyanurate having the structure A to the isocyanurate having the structure B is in a range from 0.0005 to 0.03.
