LIGHT-RESISTANT MARKING SHEET

摘要

PURPOSE:To obtain the subject sheet having excellent light-resistance and weather resistance by printing a sheet substrate with an ink composed of a specific pigment and a binder resin having ester bond group and forming a coating film having a specific thickness on the substrate. CONSTITUTION:The objective sheet having excellent long-term storage stability can be produced by printing a sheet substrate (preferably polyacrylate sheet, polyester sheet, etc.) with an ink containing (A) pigments consisting of (i) an azo pigment and/or an azo compound nickel complex pigment having N- substituted sulfamoyl group as a yellow ink pigment, (ii) a quinacridone pigment as a magenta ink pigment and (iii) a phthalocyanine pigment as a cyan ink pigment and (B) a binder resin having an ester bond group at a weight ratio (A:B) of 0.01-2.00. The thickness of the coating layer on the sheet is 0.01-30mum.
