(Problems to be Solved by the Invention) However, conventionally known squarylium compounds cannot be used in limited solvents such as aprotic polar solvents such as N-dimethylformamide, N-methylpyrrolidone, N-dimethylacetamide, and formamide. Not only are compounds only soluble, but some compounds, such as Compound A6 described in JP-A No. 59-129954, have very poor solubility. Also,
Many of these have problems such as the maximum absorption wavelength in solution deviating significantly from the oscillation wavelength of semiconductor lasers of 780 nm, 830 nm, or 850 nm, and furthermore, they have insufficient light resistance and lack stability. Due to this, there are limitations in the field of application, and in particular, it is not satisfactory for use as various information materials using laser light as a light source.
