Abstract
A resin composition includes a urethane (meth)acrylate oligomer. When the resin composition is cured with an ultraviolet light and loaded a shear force of about 2,000 Pa, the difference between the shear strain of the cured resin composition about 5 seconds after the loading and a shear strain of the cured resin composition about 300 seconds after the loading is less than about 5% A shear strain of the cured resin composition about 30 seconds after the shear force is removed from the cured resin composition is less than about 2%.
Claims20
A resin composition comprising:
- a urethane (meth)acrylate oligomer, wherein
- when the resin composition is cured with an ultraviolet light and loaded with a shear force of about 2,000 Pa, a difference between a shear strain of the cured resin composition about 5 seconds after the loading and a shear strain of the cured resin composition about 300 seconds after the loading is less than about 5%, and
- a shear strain of the cured resin composition about 30 seconds after the shear force is removed from the cured resin composition is less than about 2%.
An adhesive member comprising:
- a polymer derived from a resin composition including a urethane (meth)acrylate oligomer and having a viscosity of about 20 mPa·s or less at about 30° C. to about 50° C., wherein
- when the adhesive member is loaded with a shear force of about 2,000 Pa, a difference between a shear strain of the adhesive member about 5 seconds after the loading and a shear strain of the adhesive member about 300 seconds after the loading is less than about 5%, and
- a shear strain of the adhesive member about 30 seconds after the shear force is removed from the adhesive member is less than about 2%.
A display device comprising:
- a display panel;
- a window disposed on the display panel;
- and
- an adhesive member disposed between the display panel and the window, wherein
- the adhesive member is derived from a resin composition including a urethane (meth)acrylate oligomer,
- when the adhesive member is loaded with a shear force of about 2,000 Pa, a difference between a shear strain of the adhesive member about 5 seconds after the loading and a shear strain of the adhesive member about 300 seconds after the loading is less than about 5%, and
- a shear strain of the adhesive member about 30 seconds after the shear force is removed from the adhesive member is less than about 2%.
