Abstract
PURPOSE: To improve deterioration by light, by adding a hydroxycoumarin derivative to polyurethane.
CONSTITUTION: 0.01W10wt% (based on the amount of polyurethane) hydroxycoumarin derivative of the formula (wherein R is H, 1W3C alkyl, phenyl; R1, is H, halogen, lower alkyl, alkylenecarboxyl group, alkylenecarboxylalkyl ester group, phenyl, benzyl; R2 is H, lower alkyl; n is 1,2) is added to polyurethane. Examples of the hydroxycoumarin derivatives are 7-hydroxycoumarin, ethyl 7-hydroxy-4- methylcoumarin-3-acetate, and 5-hydroxy-3-butyl-4,7-dimethylcoumarin.
