THERMOSETTING COATING COMPOSITIONS

摘要

Disclosed are compounds of formula (1) wherein R is C4-C10 tertiary alkyl; R1 is C1-C6 alkyl or aryl; and A is a group of formula (2) or (3), wherein R2 is phenyl; or A is a C1-C10 hydrocarbyl radical, useful as crosslinking agents and a process for the preparation therefor. Also provided are novel enamel compositions containing the crosslinkers and coatings and articles coated with thermosetting coating compositions crosslinked with these novel crosslinkers.
