A method for producing a copolymer-containing varnish, a method for producing a composition, a method for producing a coating film, and a method for producing a coating film using a monomer having a specific unsaturated bond, which does not cause a problem of gelation, preferably having compatibility with biomaterials (such as biomaterial adhesion inhibition ability or cells To provide a method for producing a coating film (having a culture promoting property). Equations (1) and (2) below: (in formula (1), R 1 represents a hydrogen atom or a methyl group, R 2 represents an alkylene group having 1 to 6 carbon atoms, n represents an integer of 1 to 30, and in formula (2), R 11 is a hydrogen atom or a methyl group, and A 1 represents a monovalent organic group having cationic property) in a solvent for polymerization in the presence of a radical polymerization initiator. As a manufacturing method, the mass % of the compound represented by Formula (1) in the phosphorus containing compound contained in the said monomer mixture is 70 mass % or more, The manufacturing method. |
