Abstract
A resin composition may include at least one urethane (meth)acrylate oligomer, at least one (meth)acrylate monomer, and at least one photoinitiator. The urethane (meth)acrylate oligomer may include a first urethane (meth)acrylate oligomer derived from a phosphate ester-containing polyol represented by Formula 1, and the first urethane (meth)acrylate oligomer may have a number-average molecular weight of about 805 to about 955. Accordingly, the resin composition may exhibit the characteristics of a low viscosity before being cured, and excellent or suitable shear modulus and peel strength after being cured.
Claims12
A resin composition comprising:
- at least one urethane (meth)acrylate oligomer;
- at least one (meth)acrylate monomer;
- and
- at least one photoinitiator,
- wherein the urethane (meth)acrylate oligomer comprises a first urethane (meth)acrylate oligomer derived from a phosphate ester-containing polyol, the phosphate ester-containing polyol being represented by Formula 1, and the first urethane (meth)acrylate oligomer has a number-average molecular weight of about 805 to about 955:
- and
- wherein, in Formula 1, n1 is 3 or 4.
A method of manufacturing an adhesive member, the method comprising:
- providing, on a substrate, a resin composition comprising at least one urethane (meth)acrylate oligomer, at least one (meth)acrylate monomer, and at least one photoinitiator;
- providing first light to the resin composition to form a preliminary adhesive member;
- and
- providing second light to the preliminary adhesive member to form an adhesive member,
- wherein the urethane (meth)acrylate oligomer comprises a first urethane (meth)acrylate oligomer derived from a phosphate ester-containing polyol, the phosphate ester-containing polyol being represented by Formula 1, and the first urethane (meth)acrylate oligomer has a number-average molecular weight of about 805 to about 955:
- and
- wherein, in Formula 1, n1 is 3 or 4.
