2085123 9201027 PCTABS00010 An edge-padding adhesive is provided having a VOC content of less than 250 grams per liter less water and less exempt solvents. This edge-padding adhesive comprises by weight a) from 7.5 to 27 % dry weight of a water-based latex adhesive polymer; b) from 0.5 to 15 % of a water-dispersible transport agent comprising at least one poly(alkyleneoxide)mono-alkyl ether having alkyl groups of from 4 to 12 carbon atoms and alkylene groups of from 2 to 4 carbon atoms; and c) water. The composition contains a much lower proportion of volatile organic compounds as compared to prior edge-padding adhesive compositions for carbonless copy paper. A method of adhesively edge padding a stack of sets of collated carbonless copy paper sheets to permit the stack to be fanned apart into individual sets is also provided.
