摘要：
The present invention provides an optical recording material allows for obtaining excellent recording signal properties even at high-speed recording and is excellent in durability in both a single-sided single layer optical recording medium and a single-sided two-layer optical recording medium having a first recording layer and a second recording layer. The optical recording material contains a cyanine compound having a specific structure and a squarylium compound as dyes for optical recording layers.
