Embodiment 1

[0112] The acrylic polymer is produced by polymerizing a second mixture of 87% by weight of 2-ethylhexyl acrylate (2-EHA) as the first monomer, 10% by weight of butyl acrylate (BA) monomer, 2.5% by weight 2-hydroxyethyl acrylate (2-HEA) as the third monomer and 0.5% by weight 4-hydroxybutyl acrylate (4-HEA) as the fourth monomer -HBA) obtained by mixing.

[0113] Thereafter, an oligomer-containing additive comprising a polymer of a first mixture by adding 30 parts by weight of methoxypolyethylene glycol methacrylate ( MPEGMA), 30 parts by weight of dicyclopentenyl methacrylate (DCPMA) as a second hydrophilic monomer, and 40 parts by weight of a fluorine-based monomer (Viscoat 13f).

[0114] Next, prepare the adhesive composition that is used for protective film, described adhesive composition is the acrylic polymer that comprises 100 weight parts, the bis(trifluoromethanesulfonyl) acrylic acid as antistatic agent of 0.2 weight part Lithium imide (LiTFSI), 0.5 parts by weight...

Embodiment 2

[0117] An adhesive sheet for a protective film was manufactured in the same manner as in Example 1 except that an adhesive composition for a protective film was prepared such that the content of the oligomer-containing additive therein was 0.3 parts by weight.

Embodiment 3

[0119] An adhesive sheet for a protective film was manufactured in the same manner as in Example 1 except that an adhesive composition for a protective film was prepared such that the content of the oligomer-containing additive therein was 0.5 parts by weight.

Abstract

The present invention relates to an adhesive composition for a protective film, an adhesive comprising the same, and an adhesive sheet obtained using the same. The present invention relates to an adhesive composition, and more particularly, to an adhesive composition which can have improved low-speed peel strength with respect to a hydrophobic adherend and reduced peel electrostatic voltage by containing an oligomer-containing additive, an adhesive comprising the same, and an adhesive sheet obtained using the same, the oligomer-containing additive is a polymerization product of a mixture comprising a hydrophilic monomer and a fluorine-based monomer.

Description

technical field [0001] This application claims the benefit of the filing date of Korean Patent Application No. 10-2020-0036047 filed with the Korean Intellectual Property Office on March 25, 2020, the entire contents of which are incorporated in this application. The present invention relates to an adhesive composition for a protective film, an adhesive containing the same, and an adhesive sheet obtained using the same, and particularly relates to an adhesive composition which can have improved resistance to hydrophobicity by including an oligomer-containing additive. The low-velocity peel strength of the object and the adhesive composition of the reduced electrostatic peeling voltage, the adhesive comprising the same and the adhesive sheet obtained using the same, the oligomer-containing additive is comprising a hydrophilic monomer and based on Polymerization product of a mixture of fluorine monomers. Background technique [0002] In order to prevent product surfaces from ...
