Abstract
A method for preparing a pressure sensitive paper label is provided. The method is particularly useful on filled papers, especially papers filled with inorganic fillers containing multivalent cation. The pressure sensitive adhesive contains from 0.1 percent to 5 percent of a selected acid monomer, and 99.9 percent to 95 percent of at least one ethenically unsaturated monomer. Paper labels made by the method of this invention have superior age-resistance properties, and may be applied to a wide variety of substrates such as paper, metal, glass, wood, painted surfaces, corrugated board and plastic.
