| abstract |
The present invention is the following general formula (I)n n n n n n n n (R represents an alkyl group or hydroxyalkyl group having 1 to 30 carbon atoms, or an alkenyl group having 2 to 30 carbon atoms, n represents an integer of 1 to 4, and when n = 1, R 1 represents 1 carbon atom) A group represented by an alkyl group of -22, an alkenyl group of 2 to 22 carbon atoms or the following general formula (III),n n n n n n n n (R is the same as R above),n n n When n = 2 to 4, R 1 represents an organic group having 2 to 20 carbon atoms having n-valent carbon atoms), and when used in a synthetic resin or paint, gives a long-term stabilizing effect, Excellent resistance to extraction by acid rain or chemicals. |
