Embodiment 1

[0108]

[0109] In a reaction vessel equipped with a stirrer, a thermometer, a reflux condenser, and a nitrogen gas introduction pipe, 2,2'-isocyanurate containing 95 parts by mass of butyl acrylate (BA), 5 parts by mass of acrylic acid (AA), and a polymerization initiator A mixture of 0.2 parts by mass of nitrogen bisisobutyronitrile (AIBN) and 233 parts by mass of ethyl acetate as a solvent (reaction solution containing monomer components) was stirred at 60° C. for 7 hours under a nitrogen atmosphere (polymerization reaction). Thus, a polymer solution containing an acrylic polymer was obtained. The weight average molecular weight (Mw) of the acrylic polymer in this polymer solution was 600,000.

[0110]

[0111] To the above-mentioned polymer solution containing an acrylic polymer, an epoxy-based crosslinking agent (trade name "TETRAD C", 1,3-bis(N,N-di Glycidylaminomethyl) cyclohexane, manufactured by Mitsubishi Gas Chemical Co., Ltd.) 0.075 parts by mass, photoacid ge...

Embodiment 2～4

[0115] In the preparation of the adhesive composition, the compounding quantity of the antirust agent was set to 0.05 mass part (Example 2), 0.5 mass part (Example 3), or 1 mass part (Example 4) instead of 0.1 mass part Each PSA sheet of Examples 2-4 was produced in the same manner as the PSA sheet of Example 1 except that.

Abstract

The pressure-sensitive adhesive sheet (X) according to the present invention is provided with a pressure-sensitive adhesive layer containing a base polymer, an acid generator, a color-developing compound that develops color by reacting with an acid, and a rust inhibitor. The content of the rust inhibitor in the adhesive layer is less than 100 parts by mass relative to 100 parts by mass of the color-developing compound. This method for producing a member with an adhesive sheet comprises: a step for bonding an adhesive sheet (X) to a member; and a step for applying an external stimulus to an adhesive layer of the adhesive sheet (X) on the member, thereby developing a color of a color-developing compound.

Description

technical field [0001] The present invention relates to a method for producing an adhesive sheet and a member with the adhesive sheet. Background technique [0002] In an organic electroluminescence (EL) panel put into practical use as a display panel, a highly reflective metal electrode layer is provided as one or both of a pair of electrodes for making an organic EL element emit light spontaneously. In an organic EL panel in which elements including such a metal electrode layer are arranged to form a display screen, reflection of external light is likely to occur. [0003] As a method for preventing reflection of external light on an organic EL panel, it has been proposed to provide a layer (light-absorbing layer) having a visible light absorption capability to the extent that reflection of external light can be suppressed on the light emitting side of the organic EL element of the organic EL panel. Such a technique is described in, for example, Patent Document 1 below. ...
