A description is given of the use of naphthalene-1,8-dicarboxylic monoimides of the formula I
in which
R
1
is hydrogen, alkyl, alkenyl, cycloalkyl, cycloalkenyl, heterocycloalkyl, aryl or heteroaryl and
R
2
is a radical containing at least one π electron system containing a carbon atom and at least one further atom selected from carbon, oxygen, and nitrogen, with the proviso that the radical contains at least one atom other than carbon; to protect organic material from the damaging effects of light, of compositions which comprise at least one naphthalene-1,8-dicarboxylic monoimide of the formula I in an amount which provides protection from the damaging effects of light, and at least one organic material, and of new naphthalene-1,8-dicarboxylic monoimides I.
本文描述了萘-1,8-二羧酸单酰亚胺的使用,其化学式为I,其中R1为氢、烷基、烯基、环烷基、环烯基、杂环烷基、芳基或杂芳基,R2为至少包含一个π电子系统的基团,其中包含一个碳原子和至少另选自碳、氧和氮的一个原子,但基团至少包含一个非碳原子;用于保护有机材料免受光的损害,所述组合物包含至少一种萘-1,8-二羧酸单酰亚胺,其化学式为I,以提供免受光的损害的保护,并且至少含有一种有机材料,同时还提供了新的萘-1,8-二羧酸单酰亚胺I。
