涂膜保护片
摘要：
本发明提供高度防止对涂膜的胶糊残留的涂膜保护片。涂膜保护片(1)，在作为支撑基材(10)的聚烯烃类树脂薄膜上具有由非交联的粘合剂构成的粘合剂层(20)。支撑基材(10)中至少与粘合剂层(20)邻接的表面部分(12)由满足以下两个条件的树脂材料构成：(1)25℃的压痕弹性模量Er(25)为200MPa～1100MPa；和(2)-5℃的压痕弹性模量Er(-5)为400MPa～2400MPa。
摘要（英）：

A paint film-protecting sheet (1) is provided which effectively prevents adhesive transfer to the paint film. The paint film-protecting sheet (1) has a pressure-sensitive adhesive layer which is comprised of a non-crosslinking pressure-sensitive adhesive (20) adjacent a polyolefin-based resin film serving as a supporting substrate (10). At least a surface portion (12) of the supporting substrate that adjoins the pressure-sensitive adhesive layer satisfies the following conditions: (1) it has an indentation modulus at 25 DEG C. (Er(25)) of from 200 MPa to 1,100 MPa and (2) it has an indentation modulus at -5 DEG C. (Er(-5)) of from 400 MPa to 2,400 MPa.
