Abstract
A solid isocyanate-based composition having a glass transition temperature of at least 30° C. is produced by at least partially blocking the isocyanate groups of a polyisocyanate with a compound corresponding to the specified Formula I. This blocked isocyanate composition is useful in the production of powder coatings which are capable of being cured at temperatures of from 80 to 220° C.
