Embodiment 1

[0059] In a glass container, 62 parts by weight of ethylhexyl acrylate, 5 parts by weight of methyl acrylate, 15 parts by weight of isobornyl acrylate, 15 parts by weight of hydroxyethyl acrylate, 3 parts by weight of acryloyl morpholine and 2,2-dimethoxy-2-phenylacetophenone ( 651, Ciba Japan K.K.) mixed. The mixture was polymerized by ultraviolet irradiation using a low-pressure lamp (Sylvania BL Lamp), thereby obtaining a (meth)acrylic copolymer having a viscosity of 2,000 cP at 25°C. A (meth)acrylic acid copolymer was mixed with 0.2 parts by weight of 1,6-hexanediol diacrylate (HDDA) as a crosslinking agent and 0.3 parts by weight of a polymerization initiator ( 651) mixing, thereby preparing the adhesive composition. The adhesive composition was coated onto a polyester film having a thickness of 50 μm as a release film to form an adhesive film having a thickness of 175 μm. The opposite surface of the release film was irradiated for 6 minutes using a low-pressure lamp...

Embodiment 2

[0061] Adhesive film was prepared in the same manner as in Example 1, except that instead of adding 5 parts by weight of methyl acrylate, 63 parts by weight of ethylhexyl acrylate, 15 parts by weight of isobornyl acrylate, 20 parts by weight of of hydroxyethyl acrylate and 2 parts by weight of acryloyl morpholine.

Abstract

A UV curable adhesive composition includes a morpholine group-containing (meth)acrylic copolymer.

Description

technical field [0001] The present invention relates to an adhesive composition, an adhesive film comprising the composition, a method for producing the adhesive film, and a display member using the adhesive film. More particularly, the present invention relates to an adhesive composition that enhances durability and cuttability of the adhesive, minimizes corrosion of ITO, and improves overfilling properties by adding unsaturated morpholine to an acrylic copolymer. The present invention also relates to an adhesive film, a method for producing the adhesive film, and an optical component using the adhesive film. Background technique [0002] A capacitive touch panel is bonded to a window or film with an optically clear adhesive to detect changes in electrostatic capacitance in the window or film. The window can be formed of glass, PMMA or PC and suffers from separation, bubble generation, curing or ITO pattern exposure depending on the change of its material to the environmen...
