Embodiment

[0294] Hereinafter, specific examples of the present invention will be described together with comparative examples, but the present invention is not limited to the following examples. In addition, in the following examples and comparative examples, "parts" and "%" represent "parts by weight" and "% by weight", respectively.

[0295]In addition, "weight average molecular weight (Mw)" and "number average molecular weight (Mn)" are values ​​measured using a gel permeation chromatograph "HLC-8220GPC" manufactured by Tosoh Co., Ltd., and a separation column: Tosoh Four "TSK-GELSUPERH5000", "TSK-GELSUPERH4000", "TSK-GELSUPERH3000", and "TSK-GELSUPERH2000" manufactured by Cao Co., Ltd. were connected in series, and tetrahydrofuran at a temperature of 40°C was used for the mobile phase at a rate of 0.6ml / min. The polystyrene-equivalent weight average molecular weight and the number average molecular weight measured at the flow rate of .

[0296] In addition, in this specification, c...

Synthetic example 1

[0337]

[0338] Add polytetramethylene glycol (manufactured by Hodogaya Chemical Co., Ltd.: PTG850, hydroxyl value 127.1 mgKOH / g) 81.6 parts and 41.4 parts of isophorone diisocyanate were heated up to 60 degreeC, introducing dry air. 0.05 part of dibutyltin dilaurate was added thereto, and reaction was performed for 1 hour. Separately, 27.0 parts of 4-hydroxybutyl acrylate and 0.15 parts of hydroquinone monomethyl ether were put into the dropping funnel, and were added dropwise to the separate flask over 1 hour. After completion of the dropwise addition, stirring was continued at 80° C. for 3 hours, and the reaction was terminated when no absorption peak of the isocyanate group was confirmed in the infrared absorption spectrum, and an oligomer 2 was obtained. The weight average molecular weight of the product was 4000.

[0339] In addition, the measuring method of the hydroxyl value of this invention is as follows. Accurately measure about 1 g of a sample in a stoppered E...

Description

technical field [0001] The present invention relates to a novel active energy ray polymerizable resin composition suitable for an adhesive or a coating agent, and a laminate using the composition. Background technique [0002] Since the active energy ray polymerizable resin composition has a high polymerization rate and can usually be used in a solvent-free state, it has characteristics such as excellent workability and extremely low energy required for polymerization. Typically, the active energy ray polymerizable resin composition contains a resin component polymerizable by active energy rays and a monomer component having an α,β-ethylenically unsaturated double bond group. [0003] The resin component utilizes polyester resins, polyurethane resins, polyepoxy resins, and polyacrylic resins with low molecular weight and α, β-ethylenically unsaturated double bond groups at molecular ends. Polymer. The monomer component is polymerized together with the resin component by th...
