Abstract

The present invention provides a crosslinkable copolymer comprising structural units derived from the following monomers: monomer (A), which is a monomer of formula (I), a monomer of formula (II) or a combination thereof , in formula (I) and formula (II), A is C with hydroxyl 2 to C 6 Alkylene, R 1 is H or methyl, and R 2 , R 3 and R 4 each independently as C 1 to C 8 Alkyl; monomer (B), which is (meth)acrylic acid C 1 to C 18 Alkyl ester monomer; and monomer (C), which is a hydroxyl-containing copolymerizable monomer, wherein the monomer (B) does not have a hydroxyl group, and the monomer (B) and the monomer (C) do not have the formula ( I) or formula (II) structure. The present invention also provides a pressure-sensitive adhesive composition comprising the above-mentioned crosslinkable copolymer.

Description

【Technical field】 [0001] The present invention relates to a crosslinkable copolymer, a pressure-sensitive adhesive composition comprising the crosslinkable copolymer, and a protective film comprising the pressure-sensitive adhesive composition. The protective film can be applied to various optical elements . 【Background technique】 [0002] In recent years, display devices such as liquid crystal displays (LCDs) have been widely used in various fields. During the manufacturing process of the display device, a suitable protective film is generally required to provide temporary protection to various optical elements such as polarizers, so as to prevent the optical elements from being polluted or damaged during the manufacturing process. The protective film must be easy to remove after temporary protection and leave as little residue as possible on the surface of the optic. [0003] Generally speaking, the protective film includes a pressure-sensitive adhesive layer and a subst...
