CLEANING FILM FOR THE SCREEN PRINTING PLATE

摘要

PROBLEM TO BE SOLVED: To provide a printing cleaning sheet which keeps a balance of adhesive power and an absorbing amount of a solvent to a request for higher removal performance by solving a defect of a cleaning sheet caused by traditional material characteristics of an adhesive. SOLUTION: The cleaning film for a screen printing plate comprises a substrate and a cleaning layer provided on at least one side surface of the substrate, and the cleaning layer is provided by dispersing particles (preferably condensed silica particles) of≥100 ml/100g in an oiling amount by a measuring method based on JIS K5101 to be solidified. The cleaning layer should be preferable wherein a saturated absorbing amount to a solvent for screen printing ink is≥30 g/m2, an initial absorbing amount to the solvent for screen printing ink is≥15 g/m2in 1 s and adhesive power by a measuring method based on JIS Z0237 is≤0.1 N/25mm.
