Provided are a composition for forming a coating film, a coating film and a substrate having the coating film, which have excellent compatibility with biological substances, as well as a method for producing the same. A composition for forming a coating film having the ability to inhibit adhesion of biological substances, the composition comprising a copolymer and a solvent, wherein the copolymer is obtained by subjecting a monomer mixture to polymerization, wherein the monomer mixture comprises compounds represented by the following formulae (1), (2), and (3):

Biological material adhesion inhibitor

The invention provides a composition for forming a coating film containing a phosphoric acid group-containing polymer capable of forming a film on a substrate by a simple process and capable of maintaining film properties under a solvent environment containing water, and a coating film which is a cured product of the composition. In particular, the composition for forming a coating film contains (a) a polymer (P) containing a hydroxyl group, and the hydroxyl group is derived only from a phosphoric acid group, (b) a polycarbodiimide (C) containing a structure represented by the following formula (c-1):—N═C═N—  (c-1),and (c) a solvent.
