  • Heat, Physical Properties, Physical Change, Molecular Structure, Monomer, Polymers | High School

    Access is an AACT member benefit. Video: Ingenious Video 7: The World has a Receipt Problem Mark as Favorite (9 Favorites)

    The receipts you take home from the store – or stuff in your bag, or lose in your car -- employ a printing method that’s been around since the 1970s. Thermal printing involves heat-sensitive inks called leuco dyes that show up when they react with an acid developer embedded in the paper. Not only do these inks fade easily, but receipts that use them aren’t recyclable, and could even be dangerous to your health. Taking a cue from a failed experiment, scientists are developing a new kind of receipt paper that will use the same thermal printers without leuco dyes. Instead of acid developers, this paper is coated in reflective microspheres that collapse under heat, allowing regular ink underneath to show through.

  • Heat, Physical Properties, Physical Change, Molecular Structure, Monomer, Polymers | High School

    Access is an AACT member benefit. Activity: Ingenious: The World Has a Receipt Problem Video Questions Mark as Favorite (6 Favorites)

    In this activity, students will answer questions while watching the video The World has a Receipt Problem from the Ingenious series produced by the American Chemical Society.

This episode investigates the process of thermal printing on receipts, and the limitations related to the paper that currently prints using leuco dyes. This heat-sensitive ink appears when it reacts with an acid developer embedded in the paper. Scientists are working to develop a new kind of thermal receipt paper, that can use the same printers, however it offers many additional benefits and potential uses.
