First Claim
Patent Images
1. An optically clear laminate comprising:
- a first substrate having at least one major surface;
a second substrate having at least one major surface; and
a cloud point-resistant, optically clear adhesive composition situated 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 adhesive composition is derived from precursors that comprise;
from about 60 to about 95 parts by weight of an alkyl acrylate having 1 to 14 carbon atoms in the alkyl group;
from 0 to about 5 parts of a copolymerizable polar monomer; and
from about 5 to about 50 parts of a hydroxyl-containing monomer that has an OH equivalent weight of less than 400.

Abstract
Optically clear adhesives and laminates that include the adhesives are provided. The adhesives and laminates remain haze-free and are cloud point-resistant when placed in environments of high humidity and elevated temperature. The adhesives and laminates are useful in optical electronic display applications.
