PROBLEM TO BE SOLVED: To stably obtain a sheet having a good feel to the touch while hardly allowing a resinous deposit to appear during extrusion sheeting by forming, on a sheet, a surface layer contg. a thermoplastic elastomer, elastic fine particles, and a specified amt. of a specific lubricant. SOLUTION: This sheet has a surface layer contg. 100 pts.wt. thermoplastic elastomer [e.g. PN3429 (a thermoplastic urethane elastomer produced by Asahi Glass Co., Ltd.)], elastic fine particles [e.g. Burnock CFB 2000-40 (thermosetting polyurethane beads produced by Dainippon Ink and Chemicals, Inc.)] pref. having an average particle size of 1-50μm and pref. in an amt. of 20-200 pts.wt., and 0.1-5 pts.wt. lubricant mainly comprising a substance represented by the formula: R (COCn H2n+1 )m (wherein R is a hydrolyzable deriv.; n is 1-35; and m is 1-4) and having a mol.wt. of 700-1,500 (e.g. a butyl glycol ester of montanic acid). |
