[0067] Hereinafter, the present invention will be described in further detail by way of examples. In the following description, "part" and "%" mean "part by mass" and "% by mass".
[0068]
[0069] In a reaction vessel equipped with a stirrer, a reflux condenser, a thermometer, a UV lamp, and a nitrogen gas inlet, the acrylic monomers of the composition (%) shown in Table 1 were charged, and further added to 100 parts of the total monomers as a photopolymerization initiator. 0.01 part of an acetophenone-based initiator (manufactured by BASF Japan, trade name DAROCUR1173) and 0.01 part of n-dodecyl mercaptan as a chain transfer agent. Then, UV light was irradiated in a nitrogen atmosphere to perform partial polymerization by a bulk polymerization method, and solventless syrupy acrylic resin compositions a to c were obtained. Table 1 shows the weight average molecular weight (Mw) and concentration (%) of the polymers in the composition.

Embodiment 2
[0085] A solventless curable resin was prepared in the same manner as in Example 1, except that 0.03 part of n-dodecanethiol (nDSH) as a chain transfer agent was further added to 100 parts of syrupy acrylic resin composition a. composition to produce an adhesive sheet.
Embodiment 3
[0087]With respect to 100 parts of syrupy acrylic resin composition a, 0.03 parts of n-dodecanethiol (nDSH) as a chain transfer agent and an epoxy-based silane coupling agent (manufactured by Shin-Etsu Chemical Co., Ltd., trade name KBM-403) were further added ), except that, it carried out similarly to Example 1, and prepared the solvent-free curable resin composition, and produced the adhesive sheet.
