Description

[Technical Field]

[0001] The present disclosure relates to an active energy ray-curable resin composition and a laminate. [Background technology]

[0002] Conventionally, various plastics and the like have been used in a wide range of fields, such as the bodies and remote controls of home appliances such as refrigerators, televisions, and air conditioners, the housings and displays of information terminals such as mobile phones, smartphones, tablets, and personal computers, automobile parts, and automobile interior materials. Plastics and the like have advantages such as processability, transparency, light weight, and low cost, but have the disadvantage of being relatively susceptible to scratches.

[0003] In order to overcome these drawbacks, a resin layer having excellent scratch resistance is provided on the surface of the plastic or the like, thereby improving the scratch resistance of the surface without impairing the advantages of the plastic or the like.

[0057] Component (c2) is a compound obtained by the ring-opening polyaddition reaction of hydroxyl-containing vinyl monomers and lactones, and can be used without any particular restrictions. Note that, if other long-chain monomers (e.g., vinyl monomers having an alkylene oxide structure at the alkyl group terminal in the molecule) are used instead of component (c2), the antistatic ability of component (C) tends to be insufficient. Examples of the hydroxyl-containing vinyl monomers include hydroxyl-containing (meth)acrylates and hydroxyl-containing vinyl monomers.

In one embodiment, the molecular weight of component (c2) is preferably about 4,000 to 10,000. If the weight-average molecular weight of component (c2) is less than 4,000, the compatibility between components (A) and (C) will be insufficient, and the active energy ray-curable resin composition will tend to become cloudy and the transparency of the cured product will tend to be impaired. If the weight-average molecular weight of component (c2) is more than 10,000, it will be difficult to synthesize. In the present disclosure, the weight-average molecular weight refers to the polystyrene equivalent value measured by gel permeation chromatography.

The amount of radical polymerization initiator used during the copolymerization reaction is typically about 0.01 to 10% by mass, based on the total mass of components (c1) to (c4). A chain transfer agent may also be used during the copolymerization reaction. Examples of chain transfer agents include lauryl mercaptan, dodecyl mercaptan, 2-mercaptobenzothiazole, and bromotrichloromethane.

By making the intrinsic viscosity 0.05 dL / g or more, component (C) is less likely to bleed out onto the surface of the cured product of the active energy ray-curable resin composition, and the cured product has good antistatic properties.

[0064] Examples of nonionic antistatic agents include polyoxyethylene alkyl ethers, polyoxyethylene alkylphenol ethers, polyoxyethylene alkylamine amides, and sorbitans.

[0065] Examples of alkali metals in the antistatic agent using alkali metal salts include lithium, sodium, potassium, and the like.

[0100] The resin layer of the laminate of the present disclosure satisfies conditions 1 and 2.

[0101] Condition 1 is the indentation hardness (N / mm 2 ) is 450 or more and 600 or less. 2 ) is a numerical value corresponding to the hardness of the resin layer of the laminate. 2 ) is exemplified as an upper limit of 600, 575, 550, 525, 500, 475, etc., and as a lower limit of 575, 550, 525, 500, 475, 450, etc. In one embodiment, the indentation hardness (N / mm 2 ) is preferably 450 to 600. When it is equal to or less than the upper limit, the hardness of the laminate can be kept appropriate, and therefore a flexible laminate can be obtained. When it is equal to or more than the lower limit, the laminate can have hard coat properties. That is, it is important to be within the above range in order to achieve both a certain level of flexibility and a certain level of hard coat properties.

[0102] Condition 2 is that the breaking elongation of the resin layer of the laminate is 3.7% or more and 10.0% or less. The breaking elongation of the resin layer of the laminate is a numerical value corresponding to the hardness or softness of the resin layer. Examples of upper limits of the breaking elongation (%) of the resin layer of the laminate include 10.0, 9.0, 8.0, 7.0, 6.0, 5.0, 4.0, 3.9, and 3.8, and examples of lower limits include 9.0, 8.0, 7.0, 6.0, 5.0, 4.0, 3.9, 3.8, and 3.7. In one embodiment, the breaking elongation (%) of the resin layer of the laminate is preferably 3.7 to 10.0. By being equal to or less than the upper limit, the resin layer of the laminate is prevented from becoming too soft, and hard coat properties can be maintained. By being equal to or more than the lower limit, the resin layer of the laminate can have flexibility. That is, it is important that the breaking elongation (%) is within the above range in order to achieve both a certain level of flexibility and a certain level of hard coat properties. The breaking elongation in condition 2 refers to the ratio of the length (cm) of the laminate stretched from the length (cm) of 0% when the laminate was stretched to the length (cm) of 0% when the laminate was stretched. Specifically, using a commercially available tensile testing machine such as a Tensilon universal testing machine (product name "RTG-1250", manufactured by A&D Co., Ltd.), the sample is pulled in the longitudinal direction at room temperature at a speed of 10 mm / min, and the breaking elongation is calculated using the following formula, using the length at which cracks appear in the sample and the length of the sample before stretching. Breaking elongation (%) = 100 × (L-Lo) / Lo Lo: Length of sample before tension L: Length of the specimen when cracks begin to appear [Example]
