반응 단계
Separately, 81.4 parts of sec-butanol was added dropwise at less than 50° C. to 174 parts of tolylene diisocyanate (a mixture of 80% of 2,4-tolylene diisocyanate and 20% of 2,6-tolylene diisocyanate), and they were reacted at 60° C. until the isocyanate value of the produce became 148. Thus, a partially blocked diisocyanate having a molar ratio (tolylene diisocyanate/sec-butanol) of 1:1.1 was obtained. This product is referred to as an "isocyanate C".
