Dyes conforming to the structure: ##STR1## wherein R.sub.1 is (CH.sub.2).sub.n or ##STR2## n is an integer from 0-5 and each R is independently selected from the group consisting of straight- and branched-chain alkyl groups of about 1-6 carbon atoms, have a high extinction coefficient at 488 nm and are compatible with common binders such as cellulose-nitrate. These dyes are useful in deformable recording compositions for optical recording elements, e.g., video discs.
符合结构 ##STR1## 其中 R.sub.1 是 (CH.sub.2).sub.n 或 ##STR2## n 是0-5之间的整数,每个R独立选择自由基团,包括约1-6个碳原子的直链和支链烷基,具有在488nm处高的消光系数,并且与常见的粘合剂如硝化纤维素相容。这些染料在可变形记录组合物中是有用的,用于光学记录元件,例如视频光盘。
