Abstract
Official abstract text for this publication.
Provided is a pressure sensitive adhesive article comprising (a) a substrate (Sa), (b) in contact with said substrate (Sa), a layer (Lb) of a tackifier-free composition (Cb) that comprises one or more acrylic polymer (POLb) having Tg of −10° C. or lower, and (c) in contact with said layer (Lb), a layer (Lc) of a tackifier-containing composition (Cc) that comprises one or more tackifier and one or more hydrocarbon polymer (POLc) having Tg of −10° C. Also provided is a bonded article made by a process comprising contacting a substrate (Sd) with such a pressure sensitive adhesive article, wherein said substrate (Sd) is in contact with said layer (Lc).
First claim
Opening claim text (preview).
1 . A pressure sensitive adhesive article comprising (a) a substrate (Sa), (b) in contact with said substrate (Sa), a layer (Lb) of a tackifier-free composition (Cb) that comprises one or more acrylic polymer (POLb) having Tg of −10° C. or lower, and (c) in contact with said layer (Lb), a layer (Lc) of a tackifier-containing composition (Cc) that comprises one or more tackifier and one or more hydrocarbon polymer (POLc) having Tg of −10° C. 2 . The article of claim 1 , wherein the amount of said tackifier in said article is 12% or less by weight, based on the sum of the weights of said composition (Cb) and said composition (Cc). 3 . The article of claim 1 , wherein said acrylic polymer (POLb) comprises polymerized units of n-butyl acrylate, iso-octyl acrylate, or a mixture thereof. 4 . The article of claim 1 , wherein said tackifier is incompatible with said acrylic polymer (POLb). 5 . A bonded article made by a process comprising contacting a substrate (Sd) with the article of claim 1 , wherein said substrate (Sd) is in contact with said layer (Lc).
