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.
本发明公开了一种新型的
1,3,5-三嗪化合物和含有该化合物的组合物,其中该化合物为一般式##STR1##的化合物,其中Y、Z和可选的X分别独立地选择公式(II)、(III)和/或(IV)式的一组。这些化合物和组合物特别适用于用作可固化组合物中的
交联剂,例如涂料,特别是与含有活性氢基团的材料相结合。本发明的
1,3,5-三嗪化合物在固化过程中不会释放
甲醛挥发物,其中某些化合物可用于可在相对较低温度下固化的可固化组合物。本发明还公开了制备这些化合物的过程,含有这些化合物的组合物,以及它们的其他用途。
