7 Claims

1. A polymer-containing composition comprising:

a (meth)acryl-based copolymer (A-1),

wherein the (meth)acryl-based copolymer (A-1) contains a constitutional unit (U11) represented by Formula (11), a constitutional unit (U12) represented by Formula (12), or both, and has a weight-average molecular weight of 1,000 to 5,000, and

the (meth)acryl-based copolymer (A-1) contains a constitutional unit (U3) in addition to the constitutional unit (U11), the constitutional unit (U12), or both, and

the constitutional unit (U3) contains 2% to 50% by mass of a constitutional unit derived from a monomer (u3-1) having a substituted or unsubstituted alicyclic functional group, based on a total mass of the constitutional unit (U3),

wherein a coating film hardness of the polymer-containing composition is equal to or higher than 2.5 N/mm²,

—(C═O)—O-M-O—(C═O)— (11)

—(C═O)—O-M-R³² (12)

wherein R³²represents an organic acid residue, and M represents a divalent metal atom.
