PROBLEM TO BE SOLVED: To prevent different color inks from being mixed or dispersed, fouling due to its outflow, bleeding of printing image surface under high humidity conditions, and stickiness of image surface by having a recording layer consisting mainly of a high polymeric compound being constituted by a repeating unit indicated by a predetermined formula. SOLUTION: The recording sheet includes a recording layer consisting mainly of a polymeric compound being constituted of a repeating unit shown by formula I. In formula I, a mark A consists of formula II and formula III, and its additional form is formula IV. The repeating numbers (m), (n), (p) are positive numbers that are 1 or more. Also, a weight ratio calculated by the repeating numbers (m), (n), (p) is set in 44(m+p)/72n=80/20-90/10. The mark X is a residue moiety of an organic compound having two active hydrogen groups, and the mark R2 is a dicarboxylic acid compound residue moiety or a diisocyanate compound residue moiety. The polymer compound is made into a film so as to subsequently be adhered to a polyethylene terephthalate sheet treated with urethane in its surface. |
