Abstract

An aqueous adhesive composition including a certain emulsion polymer and an epoxysilane wherein the adhesive composition is substantially free from crosslinking agent is provided. A method for providing a substrate bearing a paper label, the adhered label having ice water resistance, and a method for removing the paper label from the substrate are also provided.

What is claimed is: 
     
         1 . An aqueous adhesive composition comprising:
 a) an emulsion polymer comprising, as copolymerized units, from 10% to 35%, by weight based on the weight of said emulsion polymer, carboxylic acid monomer and at least one second ethylenically unsaturated monomer; and   b) from 0.1% to 4%, by weight based on said emulsion polymer dry weight, epoxysilane;   
       wherein said adhesive composition is substantially free from crosslinking agent. 
     
     
         2 . A method for providing a substrate bearing a removable paper label comprising
 (a) forming the aqueous adhesive composition of  claim 1 ;   (b) applying said aqueous adhesive composition to a paper label;   (c) drying, or allowing to dry, said applied adhesive composition; and   (d) applying said label-bearing adhesive to said substrate.   
     
     
         3 . A method for removing a paper label from a substrate bearing a removable paper label comprising:
 (a) providing the substrate bearing a removable paper label of  claim 2 ; and   (b) contacting said removable label with an alkaline solution for a time and at a temperature sufficient to remove said label.
