Claim 2:
3. The curable fluorinated composition of claim 1, wherein component (B) is a fluorinated acrylic compound having the general formula (2):, wherein RfB is a divalent perfluoropolyether group,
Z1 is independently a linking group in the form of a C1-20 divalent hydrocarbon group which may contain at least one heteroatom selected from oxygen, nitrogen, and silicon, which may contain a cyclic structure therein, and in which some carbon-bonded hydrogen may be substituted by fluorine,
Q1 is independently a (a+1)-valent linking group containing at least (a+1) number of silicon atoms, which may take a cyclic structure,
“a” is an integer of 2 to 5,
Z2 is each independently a C1-100 divalent hydrocarbon group which may contain oxygen and/or nitrogen, and which may contain a cyclic structure therein,
R1 is independently hydrogen or a C1-8 monovalent hydrocarbon group,
R2 is independently hydrogen or a monovalent organic group having a (meth)acryloyl group, which may contain oxygen and/or nitrogen,
with the proviso that there are contained at least two monovalent organic groups R2 at each end of the molecule and on the average 4 to 10 monovalent organic groups R2 per molecule.
