Patent ID: 8178614

Claim:
A laminate comprising a backing material having a solvent resistant adhesive composition applied thereto, the adhesive composition including: (i) a hydroxyl terminated or urea terminated or hydrocarbon terminated unsaturated polyurethane or polyurethane-urea derived from a polyisocyanate and a hydroxyl-terminated vinyl-containing branched butadiene polymer, wherein the butadiene polymer has a molecular weight (Mn) of from 500 to 10,000, an average content of copolymerized additional monomer of from 0 to 50 weight percent, hydroxyl groups per polymer of from 2.4 to 2.8 and terminal hydroxyl groups bonded to carbon atoms adjacent to double bonded carbon atoms, and (ii) a peroxide capable of generating free radicals or a silicone hydride providing SiH, wherein components (i) and (ii) are present in amounts sufficient to provide a molar ratio of the unsaturated sites of component (i) relative to the SiH or the free radicals of component (ii) between 514 and 824 wherein the silicone hydride of component (ii) is a substantially linear hydrogen siloxane having a formula selected from the group consisting of MD e D′ f M, MD′ f M, MD e D′ f M′, M′D e D′ f M′ and M′D e M′, wherein M is defined as R 3 SiO 1/2 M′ is defined as H g R 3-g SiO 1/2 D=RRSiO 2/2 , and D′=RHSiO 2/2 where each R is independently a monovalent hydrocarbon radical of from about 1 to 40 carbon atoms, the subscripts e and f may be zero or positive wherein the sum of e and f ranges from about 10 to about 100, with the proviso that the sum of f and g is at least 2; and wherein the peroxide is one or more compound selected from the groups consisting of di-tert-butyl peroxide, dicumyl peroxide, cumene hydroperoxide, tert-butyl hydroperoxide, tert-butyl perbenzoate, tert-butyl per-3,5,5-trimethylhexanoate, tert-butyl per-2-ethylhexanoate, and benzoyl peroxide.
