This disclosure provides a family of compounds that absorb and fluoresce in the short wave infrared region (SWIR, optionally 1000 nm to 1300 nm), including hydrophilic compounds that exhibit absorption and emission spectral profiles in aqueous solutions substantially similar to those observed in organic solvents such as methanol or DMSO. The compounds can be chemically linked to biomolecules including proteins, nucleic acids, and therapeutic small molecules. The compounds are useful for imaging in a variety of medical, biological and diagnostic applications, including SWIR in vivo imaging of regions of interest within a mammal.

With a colored composition of the related art, elution resistance within a practical range is not obtained. Therefore, an object of the present invention is to provide a colored composition having better elution resistance (less dye elution) than that of the colored composition of the related art.

The present invention relates to a compound represented by the following general formula (1), a colored composition comprising the compound, and the like.

##STR00001##

{In the formula, Dye represents a dye residue, R.sub.1 represents a hydrogen atom or a methyl group, Y.sub.0 represents a single bond or the like, Y.sub.1 and Y.sub.2 each independently represent O or the like, A.sub.1 represents a specific alkylene group or the like, A.sub.2 represents an alkylene group which may have O in a chain and has a group represented by the following general formula (2) in the chain or on the terminal of the chain, and n represents 1 or 2;

##STR00002## (in the formula, R.sub.1 and Y.sub.2 are the same as described above, R.sub.3 represents a group represented by the following general formula (2-1) or the like, and A.sub.3 represents a specific alkylene group or the like;

##STR00003## [in the formula, R.sub.1, A.sub.3, and Y.sub.2 are the same as described above.].).}
