Abstract

The invention discloses an ultraviolet curable resin composition, which comprises the following components by weight: 50-90 parts of ultraviolent sensitive prepolymer resin, 10-50 parts of active diluent monomer, 5-20 part of olefin modified resin, 1-20 parts of ultraviolent free radical photoinitiator and 1-2 parts of functional auxiliary agent. The ultraviolet curable resin composition prepared by the invention is better in mobility, more excellent in optical performance and bonding strength, lower in Shore hardness, and small in impedance corrosion for ITO (indium tin oxide), can be widely applied to plane or curved surface bonding of the transparent materials in the optical field, such as a touch screen, and is capable of effectively inhibiting unevenness display of laminated bodies caused by an internal stress and an external stress and stripping of cured resin; and furthermore, the operating process is simpler, reworking is easier and the product yield is high.

Description

technical field [0001] The invention relates to an ultraviolet light curable resin composition and its application in laminating a touch screen optical display laminate. Background technique [0002] With the continuous development of technology, touch screen technology is changing with each passing day. Thinner, lighter, brighter and clearer picture quality has always been the technical development direction of the touch display industry. At present, it has gradually changed from resistive screen technology to capacitive screen technology with higher sensitivity. For this reason, higher requirements are placed on the bonding adhesive layer between the optical material laminates. [0003] In the past, most of the sheet-like adhesive sheets with pressure-sensitive properties were used, which were mostly suitable for laminating optical plastic films or boards such as PMMA and PC for resistive screens. They were not easy to be crushed, but the adhesive layer is usually thick, w...
