Abstract:
PURPOSE: To obtain excellent thermal response and coloring sensitivity by adding a specific compound.
CONSTITUTION: A compound expressed by a formula, that is, dithioacetal compound is added. In the formula, R is aralkyl and aryloxyalkyl groups and may have a substitution group (e.g. alkyl, alkoxy and halogen atoms) over such aromatic rings.
