Abstract:
An object is to provide a polymer having a high tumor/blood ratio. The present invention provides a polymer represented by the following formula (P1): wherein in the formula (P1), R represents any of a residue derived from a polymerization initiator, or a functional group; A may not be present, and when present, A represents any of a low-molecular compound, a dye, a reporter molecule, a target-binding molecule, a polymer or D; L represents a linker and L may not be present; n 1  represents an integer of 1 or more; and D represents a dye backbone of a dye having absorption in the near-infrared region.

Claim (Index 12):
A polymer represented by formula (P2), having a molecular weight of 8000 or more: wherein: n 2  represents an integer of 1 or more; L 0  is absent, or represents an alkylene group or an oxyalkylene group having 1 to 10 carbon atoms, R 0  represents a straight or branched alkyl group having 1 to 5 carbon atoms, or a group represented by formula (i3): wherein * represents binding to a nitrogen atom in the formula (P2), R 42  represents any of a Z group, a Boc group, a tosyl group and a nosyl group, and L 2  represents a straight alkylene group having 1 to 3 carbon atoms; and D 0  represents formula (d1-10): wherein ** represents binding to L 0 , or represents binding to a carbon atom at a terminal of a repeating unit in the formula (P2) when L 0  in the formula (P2) is absent.
