Definitions

  • the color developing layer in this invention is formed by using the semi-synthetic solid acid as color developer and using cojointly the zinc compound and the phenol compound.
  • this invention has been successful in providing a pressure-sensitive recording system unprecedentedly markedly improved in all the color forming rate, formed color density, fastness of the formed color image (to light, water, humidity, plasticizer, oxidizing gas, etc.), and stability (retention of color developing ability, resistance to yellowing) of the image-less areas (blank areas).
  • the formed color density, the retention thereof under high humidity conditions, and the fastness of the formed color image to NOx are improved, the fading with light is reduced, and the blank areas do not undergo the yellowing.
  • samples were prepared without adding either benzyl p-hydroxybenzoate or zinc oxide (sample A), without adding benzyl p-hydroxybenzoate but with adding the same amount of zinc oxide (sample C), and without adding zinc oxide but with adding the same amount of benzyl p-hydroxybenzoate (sample B) were prepared in the same manner as the above.
