Claims6
A phosphorus-based (meth)acrylate compound represented by Formula (I) below:
- wherein Y1, Y2, Y3 and Y4 are each independently a hydrogen atom, a halogen atom, a nitro group an amino group, a carboxyl group, a hydroxyl group, an alkyl group, an aryl group, an aralkyl group, an acyl group or an ally! group;
- A and Z are each independently an ethylene group or an isopropylene group;
- n and in are each independently 0, 1 or 2, and when n or m is 2, two As or Zs are the same as or different from each other;
- and R1 and R2 are each independently a hydrogen atom or a (meth)acryloyl group, in which at least one of R1 and R2 is a (meth)acryloyl group.
