An adhesive latex composition which is water-insoluble when dried comprising: A) a pressure sensitive adhesive latex which is alkali-dispersible when dried, such as a copolymer of n-butyl acrylate, methacrylic acid and hydroxyethyl acrylate; B) a pressure sensitive adhesive latex which is non-alkali-dispersible when dried, such as n-butyl acrylate based copolymer latex, and, optionally, one or more tackifiers. The tackifier, if used, may be a mixture of at least one tackifier having a softening point of less than 55 °C and at least one tackifier having a softening point between 55 °C and 150 °C. Paper containing the water-insoluble adhesive latex composition can be readily recycled into good quality paper. |
