To provide a material to be recorded thereon having excellent water resistance, light-resistance and electroconductivity.
The material to be recorded thereon comprises a water-soluble cationic polymer having a structural unit of 1-100 mole % represented by general formula (1), wherein A is a 3-8C linear chain alkylene group or a 4-8C alkoxymethylene group; R1, R2 and R3 are each a hydrogen atom, an alkyl group, an alkoxy group, or a saturated or an unsaturated hydrocarbon group which may be substituted with an amino group, or a saturated or an unsaturated ring containing one or more heteroatom(s) together with two or three among R1, R2 and R3, and nitrogen atoms bonding them; X is a pair of ions which are an ammonium group coordinate; and the ring a may be further substituted, or may be condensed with the other aromatic ring) on a base surface or in a coated layer on the base.
