preparation example Construction

[0061]The preparation method of the above-mentioned adhesive composition is not particularly limited as long as it includes the above-mentioned components. From the viewpoint of process simplification, it is preferably prepared by the following method: first, prepare a dispersion liquid of metal nanoparticles and an aromatic low-molecular-weight polymer The solids obtained by mixing and drying the solutions of the solids were then dissolved in the monomer components. The dispersion medium of the metal nanoparticle dispersion liquid is water or an organic solvent, and the solution of the aromatic low-molecular polymer can be used in the form of a solution in an organic solvent such as toluene, ethyl acetate, or methyl ethyl ketone. A mixture of a metal nanoparticle dispersion and an aromatic low-molecular polymer solution is usually dried at room temperature without heating to obtain a solid by removing the solvent. In addition, at the time of preparation of the adhesive compos...

Embodiment 1

[0089] 100 parts of n-butyl acrylate, 1 part of 4-hydroxybutyl acrylate, 0.05 parts of a photopolymerization initiator (manufactured by Ciba Corporation of Japan, Irgacure 651) and 0.4 parts of a photopolymerization initiator (manufactured by Ciba Corporation of Japan, Irgacure 184) After mixing and fully replacing nitrogen, intermittently irradiate for 5 minutes with a high-pressure mercury lamp (UVA illuminance: 0.271W / cm 2 ) to obtain a viscous slurry. The degree of polymerization of monomers in this slurry was 12.5%. 1.0 parts of trimethylolpropane triacrylate and 20 parts of styrene low-molecular weight polymer (SX-85, weight average molecular weight Mw=1550, manufactured by Yasuhara Chemical Co., Ltd.) were blended into the slurry, and uniformly mixed to prepare an ultraviolet curing type Adhesive composition. Apply this ultraviolet curable adhesive composition to the polysiloxane-treated, 38 μm polyethylene terephthalate (PET) film (DIAFOIL MRN38, manufactured by Mits...

Embodiment 2

[0091] Except that the styrene low-molecular-weight polymer in Example 1 was changed to a styrene low-molecular-weight polymer (SX-100, Mw=2000, manufactured by Yasuhara Chemical Co., Ltd.), the adhesive sheet was produced in the same manner as in Example 1.

Abstract

Provided is an adhesive agent composite in which an aromatic low-molecular-weight polymer and metal nanoparticles are stably mixed. An adhesive agent layer having a low haze value can be formed and desired adhesive properties can be obtained without going through a complicated process. The ultraviolet-curable adhesive agent composite is characterized in that the haze value when said composite has become an adhesive layer is no greater than 10%, and is further characterized by containing: a monomer component containing acrylic monomers; an aromatic low-molecular polymer having a weight-average molecular weight of at least 500 and no greater than 4000, as measured by gel permeation chromatography; and a photopolymerization initiator. The ultraviolet-curable adhesive agent composite preferably also contains metal nanoparticles having a mean diameter of no more than 20 nm.

Description

technical field [0001] The present invention relates to an ultraviolet-curable adhesive composition containing an aromatic low-molecular polymer and metal nano-ions, which can be used in various applications, an adhesive layer formed from the adhesive composition, and a substrate on a support. An adhesive sheet having the adhesive layer on at least one side of the present invention and a method for producing the same. Background technique [0002] Attempts are being made to improve the physical properties of adhesives or polymer compositions represented by mechanical strength by mixing aromatic low-molecular-weight polymers and various nanoparticles in adhesives or polymer compositions that can be used in a wide range of applications . Regarding the mixing of nano ions, the generally adopted method is to perform surface treatment of the nanoparticles, or to process the composition with various dispersing machines, so that the nanoparticles are uniformly dispersed in the com...
