Abstract:
New classes of 1,3,5-triazine compounds and compositions containing the same are disclosed, which compounds are of the general formula ##STR1## wherein each of Y, Z and optionally X are independently selected from a group of the formula (II), (III) and/or (IV) ##STR2## These compounds and compositions are particularly suitable for use as crosslinking agents in curable compositions such as coatings, particularly in combination with active hydrogen groups-containing materials. The 1,3,5-triazine compounds of the present invention do not release formaldehyde as a volatile by-product during cure, and certain of these compounds may be used in curable compositions which may be cured at relatively low temperature. Processes for preparing such compounds, compositions containing the same, as well as additional uses thereof, are also disclosed.
