Patent ID: 7763360

Claim:
A laminate article comprising at least one transparent interlayer, wherein the transparent interlayer is obtained from a resin composition consisting essentially of copolymerized units of ethylene and from 20 to 23 wt % of copolymerized units of a carboxylic acid monomer selected from acrylic acid or methacrylic acid, wherein 20% to 35% of the acid groups are neutralized; and the resin has a melt index of about 60 g/10 min or less prior to neutralization, and wherein the laminate article has a haze of 3% or less after heating to a temperature of at least 120° C. and cooling to 40° C. at a rate of less than 1° C./min; and further wherein the peel strength of the laminate article is from 16 to 47 lbs/inch when measured at an angle of 90° at a peel rate of 1 inch/min, provided that the transparent interlayer is an extruded sheet having a moisture level of 0.066 wt % or less; and further wherein said transparent interlayer has an adhesion to glass of at least 200 J/m 2 , when measured by Double-Cantilever Beam testing; and said transparent interlayer has an impact toughness of at least 300 J/m 2 , when measured according to ASTM 1822.
