摘要:
Activated clays are a color developer for the common use of carbonless copying paper. They reacts with crystal violet lactone, a leuco dye, to form bright blue quinoid colored group with a large π bond by capturing electron pair of functional group from lactone[1].However, there exist in this reaction a problem of color stability fading in the light[2]. It is important to understand the color developing nature of clays for overcoming this problem. But unfortunately, very little work has been reported on this area[2].
