INKJET PAPER FOR LASER PROCESSING, INK JET PRINTING AND ITS WORKPIECE

摘要

PROBLEM TO BE SOLVED: To provide inkjet paper for laser processing having excellent water resistance, bar code printability, ink dryability and printed part uniformity in full color printing in a high-speed ink jet system and having sufficient discoloration resistance in laser processing.SOLUTION: In the inkjet paper on which a surface treating agent containing a cationic material, a water soluble polymer and a styrene acrylic copolymer without a pigment is applied on both surfaces or one surface of base paper, an anion required amount of an extract extracted from the inkjet paper using distilled water is 5 μeq/L or more and 30 μeq/L or less.
