    摘要: This invention relates to washable coloring compositions comprising specific low-molecular weight styrene-maleic anhydride copolymers. Such copolymers provide excellent washability enhancing performance in association with colorants and inks. Also, these specific compounds exhibit low viscosities which allow for greater amounts of washability enhancing copolymers to be added within colorant and ink formulations while simultaneously permitting the retention of sufficiently low overall viscosities of the target compositions. Such copolymers provide highly effective prevention of permanent colorations to certain substrates, such as skin, clothing, and the like, by the inks, dyes, and the like, within the target compositions. Marker styluses, writing implements, and other colorant transfer devices, containing these inventive compositions, are also encompassed within this invention.
