Class Information
Number: 503/202
Name: Record receiver having plural interactive leaves or a colorless color former, method of use, or developer therefor > Having a colorless color-former, developer therefor, or method of use > Color developed by mere decomposition of color-former
Description: Subject matter in which the color-former is such that breaking up the color-former molecule) (e.g., by ionization, etc.) is sufficient to form a color without the need for the color-former molecule or fragment of it to react with another molecule.
