BLOCKED POLYISOCYANATE AND WATER-SOLUBLE CLEAR COAT COMPOSITION COMPRISING THE SAME

The present invention relates to a blocked polyisocyanate obtained from a polyisocyanate compound and a blocking agent and, more specifically, to a blocked polyisocyanate containing a first block isocyanate group in which an isocyanate group is blocked by a silane-based blocking agent, a second bloc...

Zusammenfassung:	The present invention relates to a blocked polyisocyanate obtained from a polyisocyanate compound and a blocking agent and, more specifically, to a blocked polyisocyanate containing a first block isocyanate group in which an isocyanate group is blocked by a silane-based blocking agent, a second block isocyanate group in which the isocyanate group is blocked by a polyalkylene polyol blocking agent, and a third block isocyanate group in which the isocyanate group is blocked by a pyrazole-based blocking agent. 본 발명은 폴리이소시아네이트 화합물 및 블로킹제로부터 얻어지는 블록 폴리이소시아네이트로서, 실란계 블로킹제에 의해 이소시아네이트기가 블록되어 있는 제1 블록 이소시아네이트기, 폴리알킬렌폴리올 블로킹제에 의해 이소시아네이트기가 블록되어 있는 제2 블록 이소시아네이트기, 및 피라졸계 블로킹제에 의해 이소시아네이트기가 블록되어 있는 제3 블록 이소시아네이트기를 함유하는 블록 폴리이소시아네이트에 관한 것이다.
