Claim 7:
8. The surface treatment agent according to claim 1, wherein the fluorine-free monomer (A2) is at least one monomer selected from the group consisting of a compound of the formula:

CH2═C(—X1)—C(═O)—Y1—R1 

wherein X1 is a hydrogen atom, a monovalent organic group or a halogen atom,
Y1 is —O— or —NH—, and
R1 is a hydrocarbon group having 7 to 40 carbon atoms;, a compound of the formula:

CH2═C(—X2)—C(═O)—Y2—Z1(—Z2—R2)p 

wherein X2 is a hydrogen atom, a monovalent organic group or a halogen atom,
Y2 is —O— or —NH—,
Z1 is a direct bond, or a divalent or trivalent hydrocarbon group having 1 to 5 carbon atoms,
Z2 each is independently a direct bond, or a divalent to tetravalent linking group having at least one group selected from —O— and —NH—,
R2 each is independently a hydrocarbon group having 7 to 40 carbon atoms, and
p is 1 or 2; and, a compound of the formula:

R22—C(═O)—NH—R23—O—R21 

wherein R21 is an organic residue having an ethylenically unsaturated polymerizable group,
R22 is a hydrocarbon group having 7 to 40 carbon atoms, and
R23 is a hydrocarbon group having 1 to 5 carbon atoms.
