Embodiment 1

[0092] In a reaction vessel equipped with a cooling tube, a nitrogen tube, a thermometer, and a stirring device, 68 parts by weight of butyl acrylate, 29 parts by weight of methyl methacrylate, and 3 parts by weight of 2-hydroxyethyl acrylate are added as a polymerization initiator. 0.1 parts by weight of 2,2'-azobis(2-amidinopropane) dichloride, 1.5 parts by weight of sodium dodecylbenzene sulfonate as an emulsifier, and 100 parts by weight of water, emulsion polymerization 5 at 80°C After hours, the pH was adjusted to 7.0 with 15% by weight ammonia water to obtain a copolymer emulsion having a solid content of 50% by weight.

[0093] The emulsion is salted out with hydrochloric acid, washed with water, and dried to obtain an acrylic copolymer. The acrylic copolymer was dissolved in toluene, and 3 parts by weight of trimethylolpropane benzylidene diisocyanate was added to the solution with respect to 100 parts by weight of the solid content of the acrylic copolymer, and mixed to ...

Abstract

An object of the present invention is to provide a surface protecting film which dramatically improves an efficiency of transporting and storing a mother glass, has better peelability from an adherend when peeled without polluting a mother glass surface, and gives reinforcing effect, and use thereof, by using a pressure-sensitive adhesive protecting film. There is provided a film for protecting a mother glass for a flat panel display, characterized in that a rear side is unevenly-processed, and a pressure-sensitive adhesive side is smoother than a rear side.

Description

Technical field [0001] The present invention relates to a sample glass protective film for flat panel displays for protecting the surface of sample glass used in the manufacture of various display devices and the like, and its use, and is particularly useful as a technique for transporting and protecting sample glass. Background technique [0002] Glass substrates are used in the manufacture of flat panel displays such as liquid crystal displays, plasma display panels, and organic EL displays, but glass plates manufactured in factories are distributed (transported) as sample glass and processed into glass substrates. When the glass surface is damaged due to the transportation and storage of the sample glass, and the transportation of the sample glass, the customer’s storage, etc., it becomes the cause of the decrease in the effective utilization rate and the adverse effect on the quality. Therefore, it is usually possible to make the glass surface Keep the shape in contact with e...
