Abstract
There is provided a resin composition for soft relining material that can meet the performances required in a soft relining material for denture base, such as a proper softness and fitness between a denture base and an oral mucosa, without using a phthalate-based plasticizer widely used in the conventional art resin composition for soft relining material, which is pointed out to have a possibility for influencing living bodies as an endocrine disruptor. The soft resin composition for denture base is constructed of (a) a (meth)acrylate monomer having at least one unsaturated double bond; (b) an aliphatic acid ester-based plasticizer; (c) a (meth)acrylate polymer or copolymer; and (d) a polymerization initiator.
Claims5
A resin composition for soft relining material, comprising:
- 2 to 50% by weight of (a) a (meth)acrylate monomer having at least one unsaturated double bond;
- 20 to 80% by weight of (b) a plasticizer selected from the group consisting of diisobutyl adipate, diisobornyl adipate, dibutyl sebacate and tributyl citrate;
- 10 to 70% by weight of (c) a (meth)acrylate polymer or copolymer;
- and
- 0.005 to 5 parts by weight, based on 100 parts by weight of the total sum of the components (a), (b) and (c), of a polymerization initiator (d).
