Abstract:
An ink imaging sheet comprising a base sheet and an ink imaging layer formed on at least one surface of the base sheet, wherein the base sheet is constituted of a tearable stretched styrenic resin sheet in which:the tearing strength of said stretched styrenic resin sheet is 0.05 to 0.25 Kgf/mm; the ratio of the tearing strength of a 130 &mgr;m-thick stretched specimen of said styrenic resin sheet (SST) to the tearing strength of a 100 im-thick polye thylene terephthalate film (SPET) is SST/SPET=0.01/1 to 0.7/1; and the draw ratios of said stretched styrenic resin sheet are 1.5 to 3 times lengthwise and 1.5 to 3 times widthwise, wherein said ink imaging layer comprises a cationic polymer comprising a cationic monomer and an alkoxysilyl group-containing crosslinking monomer, a hydrophilic polymer, and a particulate lubricant.
