Abstract
The present invention is a two-part adhesive layer including a first, optically clear adhesive composition and a second, light-blocking adhesive composition substantially surrounding the first, optically clear adhesive composition.
Claims18
A two-part adhesive layer comprising:
- a first, optically clear adhesive composition;
- and
- a second, light-blocking adhesive composition substantially surrounding the first, optically clear adhesive composition,
- wherein the first, optically clear adhesive composition has a luminous transmission of greater than about 90%, a haze of less than about 2%, and opacity of less than about 1% in the 400 to 700 nm wavelength range.
1 more element
A laminate comprising:
- a first substrate;
- a second substrate;
- and
- a two-part adhesive layer situation between and in contact with at least one major surface of the first substrate and at least one major surface of the second substrate, wherein the two-part adhesive layer comprises:
- a first, optically clear adhesive composition;
- and
- a second, light-blocking adhesive composition substantially surrounding the first, optically clear adhesive composition,
- wherein the first, optically clear adhesive composition has a luminous transmission of greater than about 90%, a haze of less than about 2%, and opacity of less than about 1% in the 400 to 700 nm wavelength range.
5 more elements
A method of forming a two-part adhesive layer comprising:
- dispensing a first adhesive composition, wherein the first adhesive composition is optically clear;
- and
- dispensing a second adhesive composition, wherein the second adhesive composition is light-blocking, substantially around the first adhesive composition,
- wherein the first, optically clear adhesive composition has a luminous transmission of greater than about 90%, a haze of less than about 2%, and opacity of less than about 1% in the 400 to 700 nm wavelength range.
