having a molecular weight of 10,000 to 200,000. Additional limitations are described in
the following illustrative claim.
THE CLAIM
Claim 1 is illustrative of appellants’ invention and is reproduced below:
1. A UV curable resin composition for coating which comprises at least the
coating film forming components:
(a) 10 - 70 % by weight of a mono- or bi- functional monomer having a
molecular weight of 130 - 700, and having an ether bond and one or two
acryloyloxy groups per molecule,
(b) 5 - 60 % by weight of an aliphatic urethane acrylate oligomer,
(c) 10-30 % by weight of a methyl methacrylate polymer having a
molecular weight of 10000 to 200000,
and which also includes as necessary ingredients, relative to 100 parts by weight of
said coating film forming components:
(e) 2 - 10 parts by weight of a photopolymerization initiator, and
(f) 2 - 20 parts by eight of a UV absorber.
