Description of the Invention: [Technical Field] The present invention relates to a touch containing a (meth) acrylate oligomer having a polyisoprene, a polybutadiene or a polyurethane on a skeleton and a softening component The control panel is followed by a photo-curing type composition; one containing the aforementioned (meth) acrylate oligomer, a softening component, and a specific (meth) acrylate monomer or thiol compound, and the cured product has a specific A photocurable type subsequent composition having an elastic modulus and an elongation at the time of rupture of the crucible; and a touch panel or a display panel which is bonded thereto. [Prior Art] In order to mount a touch panel on a display body such as an LCD, a resistive film type, an electrostatic capacity type, an electromagnetic induction type, an optical type, or the like can be used. On these touch panels, it may be necessary to fit a decorative panel for better design of the appearance, or to fit an Icon sheet that can specify a touch position. In addition, the ® capacitive touch panel is a structure in which a transparent electrode is formed on a transparent substrate and a transparent plate is attached thereto. Conventionally, the decorative board and the touch panel are bonded together, the icon sheet is attached to the touch panel, and the transparent substrate and the transparent plate are formed on the electrostatic capacitance type touch panel. It is carried out by using a flaky double-sided adhesive sheet or by adhering to one side of the object. In the technique of using such an adhesive material, there is a problem that the adhesion is incomplete or that air bubbles are mixed in the bonding surface. Among them, in particular, when printing is performed on the bonding surface, there is a problem that bubbles are likely to remain in the difference portion of the printed portion, that is, the printed portion. Further, in recent years, the glass of the display body of LCD or the like has become thinner, and when the glass is thinned, the problem of deformation of the LCD is liable to occur due to external stress. When a display body such as a thin glass LCD or an optical functional material such as an acrylic plate or a polycarbonate plate is bonded, the glass expands differently from propylene or the like, or an acrylic plate or a polycarbonate or the like. The deformation of the plastic molding material during molding causes the formation deformation to be alleviated or the moisture absorption/drying to occur in the heat resistance test or the moisture resistance test, and the surface precision such as dimensional change or bending changes. In the conventional adhesive (for example, Patent Document 1), in order to suppress such deformation, there are problems such as peeling of the surface, rupture of the LCD, or occurrence of spots on the LCD. CITATION LIST Patent Literature PATENT DOCUMENT 1: JP-A-2004-77 8 8 7 SUMMARY OF THE INVENTION PROBLEM TO BE SOLVED BY THE INVENTION The object of the present invention is to provide a continuation composition which is characterized in that it can be solved. : When the decorative panel and the graphic sheet are attached to the touch panel, or when the transparent substrate and the transparent plate on which the transparent electrode is formed on the electrostatic capacitance type touch panel are bonded together, sufficient adhesion is provided and no bubbles are provided. However, when the display body and the optical functional material are bonded together, the resulting surface peeling off, the display body -6-201026801 glass breakage, etc., the problem of the conventional technology . MEANS FOR SOLVING THE PROBLEMS The present inventors have found that in a photocurable type subsequent composition, a (meth) acrylate oligomer having polyisoprene, polybutadiene or polyurethane on a skeleton is contained.

The composition was analyzed for its characteristics by various tests as described below. The results are shown in Tables 3 to 5 - 25 - 201026801. In any of Examples A to I, no bubbles were present in the thermal shock test, the heat resistance test, and the moisture resistance test. The elastic modulus and elongation at break were measured using a material tester manufactured by Shimadzu Corporation using a JISZ 1 702 No. 3 bell test piece (thickness: 1 mmt) at a speed of 10 m/min. Further, the Yaling test piece was made by using a diffused metal halide lamp with a conveyor belt and hardened with an integrated light amount of 6000 mJ/cm2. The shrinkage rate is determined by nS-K-68 33 according to the liquid specific gravity and hardener ratio _ weight, and then the volume ratio of the two is calculated. The penetration rate is based on the reference side glass (1 mm thick), sample chamber. On the side of the 1 mm thick glass, the resin composition was hardened to a thickness of 1 mm to prepare a test piece, and then measured by a wavelength of 400 nm to 800 nm using a UV-visible spectroscope manufactured by JASCO Corporation. The measurement was also carried out in the same manner after 500 hours at 85 ° C and at a rate of 60 ° C / 90% after 500 hours. The refractive index was measured in a sheet having a thickness of 300 μm/m, and was measured by an Abbe's Abbe refractometer (D line, 25 ° C). © Thermal shock test, a 0.8 mxn thick acrylic sheet (MR-200 manufactured by Mitsubishi Rayon Co., Ltd.) and a 0.8 mm thick glass plate (30 x 40 mm), which are laminated to a hardened thickness using a photohardenable resin composition. ^m test piece (glass/propylene test piece): or '0.8 mm thick glass plate and 0.7 mm thick glass plate (30x40 mm), hardened thickness 100 4 using a photohardenable resin composition Sheet (glass/glass test piece).
