Abstract: A resin is provided, wherein the resin is formed by reacting 1 part by mole of a multi-isocyanate core with 3 to 4.5 parts by mole of diol to form an intermediate, and then reacting the intermediate with 3 to 4.5 parts by mole of first diisocyanate. The multi-isocyanate core can be a multi-isocyanate compound with more than two isocyanate groups. Alternatively, the multi-isocyanate core can be formed by reacting a second diisocyanate with a multi-hydroxy compound, and the multi-hydroxy compound has more than two hydroxy groups.
