Abstract
Official abstract text for this publication.
Described is a pressure-sensitive adhesive (PSA) polymer formed from (i) 50%-95% by weight of n-butyl acrylate, (ii) 1%-20% by weight of ethyl acrylate, (iii) 1%-20% by weight of vinyl acetate, (iv) 0.1%-5% by weight of at least one ethylenically unsaturated acid or ethylenically unsaturated acid anhydride, and (v) 0% to 30% by weight of other ethylenically unsaturated compounds different from the monomers (i) to (iv). The PSA polymer can be used for producing self-adhesive articles, more particularly paper labels or film labels.
First claim
Opening claim text (preview).
The invention claimed is: 1. A pressure-sensitive adhesive polymer, comprising in a polymerized form: (i) from 55.25% to 85.25% by weight of n-butyl acrylate, (ii) from 5% to 7% by weight of ethyl acrylate, (iii) from 5% to 7% by weight of vinyl acetate, (iv) 0.2-3% by weight of (meth)acrylic acid, and (v) 4% to 34% by weight of at least one monomer selected from the group consisting of 2-ethyl hexyl acrylate, styrene, and hydroxypropyl acrylate, wherein the pressure-sensitive adhesive polymer exhibits a quickstick value of from 6.1 N/25 mm to 8.7 N/25 mm at 5° C. when applied to paper and bonded to polyethylene. 2. A pressure-sensitive adhesive dispersion, comprising an aqueously dispersed pressure-sensitive adhesive polymer according to claim 1 , which is prepared by emulsion polymerization. 3. A self-adhesive article obtained by coating a carrier material with the pressure-sensitive adhesive polymer according to claim 1 . 4. A self-adhesive label, comprising the self-adhesive article according to claim 3 . 5. A self-adhesive paper label or film label, comprising the self-adhesive article according to claim 3 . 6. A self-adhesive article obtained by coating a carrier material with the pressure-sensitive adhesive dispersion according to claim 2 . 7. A self-adhesive label, comprising the self-adhesive article according to claim 6 . 8. A self-adhesive paper label or film label, comprising the self-adhesive article according to claim 6 .
