Abstract
The present invention is to provide a photocurable fluorinated copolymer composition which is uniform and excellent in transparency, and a coating film layer obtainable by using it, is excellent in heat resistance and abrasion resistance and exhibits a particularly excellent weather resistance performance. The photocurable fluorinated copolymer composition comprises a specific fluorinated copolymer (A), a specific hydrolysable silane compound (B), an epoxy resin (C) having a cyclohexane ring structure, and a photoreaction initiator (D).

A photocurable fluorinated copolymer composition comprising the following fluorinated copolymer (A), hydrolysable silane compound (B) and epoxy resin (C), and a photoreaction initiator (D):
- Fluorinated copolymer (A):
- a copolymer containing repeating units (a-1) derived from a fluoroolefin, repeating units (a-2) derived from a monomer represented by the following formula (1), and repeating units (a-3) derived from a monomer having at least one functional group selected from the group consisting of a hydroxy group, a carboxy group and an alkoxysilyl group:
- (in the formula (1), R1 is a hydrogen atom or a C1-6 alkyl group which may have an etheric oxygen atom, and A is a group selected from a vinyl group, an allyl group, an isopropenyl group and a (meth)acryloyl group),
- Hydrolysable silane compound (B):
- a hydrolysable silane compound represented by the following formula (2):
- Si(OR2)aR34-a (2)
- (in the formula (2), each of R2 and R3 which are independent of each other, is a C1-10 alkyl group, and a is an integer of from 2 to 4),
- Epoxy resin (C):
- an epoxy resin having a cyclohexane ring structure.
