Abstract
The present invention relates to articles comprising a retroreflective sheeting, a release liner and an adhesive layer sandwiched between the substrate and release liner and methods of manufacturing such articles. The release liner has a relatively high coefficient of friction and has shrinkage properties that are substantially the same as or greater than the retroreflective sheeting. The article exhibits good roll stability, being substantially free of defects when supplied in a roll form.
Claims17
An article comprising an adhesive layer disposed between retroreflective sheeting and a polymeric liner, the liner having an adhesive-facing surface releasably adhered to the adhesive;
- wherein the adhesive-facing surface has a coefficient of friction of at least about 0.30;
- the retroreflective sheeting exhibits shrinkage such that (1-L/LO) is greater than 0.05% at 10 days according to Shrinkage Test Method B;
- and the liner exhibits shrinkage at 10 days according to Shrinkage Test Method B ranging from substantially the same as to greater than the retroreflective sheeting.
