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 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 composition (Cc) that comprises one or more acrylic polymer (POLc) that comprises 20% to 90% polymerized units of one or more high-aliphatic vinyl monomer, by weight based on the weight of said polymer (POLc). Also provided is a bonded article made by a process of 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).
The invention claimed is: 1. A pressure sensitive adhesive article comprising (a) a substrate (Sa), (b) in contact with said substrate (Sa), a layer (Lb) of a pressure-sensitive adhesive 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 composition (Cc) that comprises one or more acrylic polymer (POLc) that comprises 20% to 90% polymerized units of one or more high-aliphatic vinyl monomer, by weight based on the weight of said polymer (POLc), wherein said high-aliphatic vinyl monomer is selected from the group consisting of structure (I), structure (II), and mixtures thereof, wherein structures (I) and (II) are wherein R 1 is hydrogen or methyl, and R 2 is selected from iso-butyl, tert-butyl, 2-ethylhexyl, alkyl groups having 8 to 18 carbon atoms, stearyl, isobornyl, and mixtures thereof; wherein said acrylic polymer (POLb) comprises 10% or less by weight of said high-aliphatic vinyl monomer. 2. The article of claim 1 , wherein said high-aliphatic vinyl monomer is a structure (I). 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. A bonded article made by a process of contacting a substrate (Sd) with the article of claim 1 , wherein said substrate (Sd) is in contact with said layer (Lc). 5. The bonded article of claim 4 , wherein said substrate (Sd) is a polyolefin.
