Zusammenfassung:	PURPOSE:To obtain titled sheet useful for removing dusts, etc. through sticking, by first coating on a specific substrate a weak tackifier comprising each specific amount of natural (or synthetic) rubber and tackifying resin followed by laminating a releasing film constituted by thermoplastic resin. CONSTITUTION:The objective sheet can be obtained by first coating on (A) a substrate constituted by thermoplastic resin (e.g., polypropylene) sheet, (B) a weak tackifier comprising (i) 60-90wt% of natural or a synthetic rubber (e.g., a styrene-butadiene-styrene block copolymer) and (ii) 10-40wt% of a tackifying resin (e.g., rosin or a derivative therefrom), followed by laminating on a thermoplastic resin film, a releasing film made by baking a silicone. EFFECT:Giving high weatherability, etc. USE:Applicable to mats for sickroom, computer-operating room and various laboratory entrances, and to brushes for clothes and shoes.
