Weakly basic hindered amines compounds having carbonate skeletons, synthetic resin compositions and coating compositions

摘要

Hindered amines represented by the general formula (I): (wherein R is an alkyl or hydroxyalkyl group having 1 to 30 carbon atoms or alkenyl having 2 to 30 carbon atoms; n is an integer of 1 to 4; when n is 1, R1 is alkyl having 1 to 22 carbon atoms, alkenyl having 2 to 22 carbon atoms, or a group represented by the general formula (III): (R is as defined above), while when n is 2 to 4, R1 is an n-valent organic group having 2 to 20 carbon atoms). When added to synthetic resins or coating materials, the amines can impart long-period stabilizing effect to the resins or the materials and exhibit excellent resistance to extraction with acid rain or chemicals.
