[0108]

[0109] Butyl acrylate (412.7 g), methyl acrylate (117.9 g), and acrylic acid (10.4 g) were weighed and mixed well as monomers to obtain a polymerizable monomer mixture (A1). 160 g of ethyl acetate and 300 g of the polymerizable monomer mixture (A1) were charged into the flask. In addition, 300g of the polymerizable monomer mixture (A1), 16g of ethyl acetate and 0.15g of Naipa-BMT-K40 (polymerization initiator, produced by NOF Co., Ltd.) were added to the dropping funnel, and fully mixed to make a solution for dropping. Mixture (A2). While blowing nitrogen gas at 20ml / min, the temperature in the flask was raised to 95°C, and the polymerization initiator Naipa-BMT-K40 (0.15g) was put into the flask to initiate the polymerization reaction. The dropping mixture (A2) was dropped from the dropping funnel over 90 min. After completion of dripping the mixture for dripping (A2), aging was performed for 6 hours while diluting with ethyl acetate according to the increase in ...

Abstract

The invention provides a bonding type optical film and an adhesive composition. The invention provides a method for improving the endurance of pigments in a bonding layer having a diimide pigment. The bonding type optical film includes a near infrared ray absorbability bonding layer having a acrylic acid series polymer and diimide pigment, and a base material layer. Needle-shaped aggregates are scattered in the near infrared ray absorbability bonding layer.

Description

technical field [0001] The present invention relates to an adhesive optical film and an adhesive composition. More specifically, the present invention relates to an adhesive optical film having a near infrared absorbing adhesive layer and an adhesive composition for forming the adhesive layer thing. Background technique [0002] In terms of its light-emitting principle, the plasma display can emit electromagnetic waves, neon light, and near-infrared rays while emitting visible light. Due to the adverse effects of these rays, it is necessary to shield them. Therefore optical films are used. [0003] In addition to the above-mentioned functions, in order to improve image quality by providing multiple functions such as preventing reflection on the audience side and improving contrast, an optical film laminated with multiple layers is used. However, in recent years, there is a demand for simplifying these optical films, and there is a tendency to reduce the cost by simplifyin...
