Problems solved by technology

When particles are mixed, the film thickness must be thinned in order to form unevenness on the surface, so the film strength is weakened, it is easily damaged, and the coating film characteristics deteriorate
Also compromised photochemical properties

Embodiment 1

[0160] 1 part by weight of the acrylic copolymer of Preparation Example 1 (SP value of the resin: 10.2, Tg: 113° C., weight average molecular weight Mw = 5200) as the first component, 99 parts by weight of Aronix M305 (Toagosei Co., Ltd. pentaerythritol triacrylate, SP value: 12.7), as a silicone compound 0.1 parts by weight FM-7711 (Chitsuso Co., Ltd. reactive silicone, number average molecular weight Mn = 1000), 7 parts by weight 2-Methyl-1-[4-(methylthio)phenyl]-2-morpholinopropan-1-one, which is a photoinitiator, is mixed in isopropanol as a solvent to make a non-volatile component rate up to 40% by weight of the solution.

[0161] The solution was coated on a PET film substrate (100 μm) with a bar coater (No.10) at 23°C, dried at 80°C for 1 minute to form a film with a thickness of 5 μm, dried to remove the solvent, and then irradiated with an ultra-high pressure mercury lamp Ultraviolet (350nm), energy up to 300mJ / cm 2, to solidify the film. For the obtained anti-bloc...

Embodiment 2-9

[0190] In the same manner as in Example 1, the antiblocking layered structures of Examples 2 to 9 were prepared and evaluated in the same manner as in Example 1. Tables 1 and 2 show the results. In embodiment 2-9, change the acrylic copolymer used in embodiment 1 into listed in the table, used monomer, silicone compound, use and embodiment 1 identical, embodiment 5 and In Example 9, the following silica particles were used, and in Example 6, the following acrylic particles were used.

Abstract

The invention relates to a lability antiblocking light-settability resin composition, a solidified antiblocking structure coated on basis materials and a preparation method. The invention provides a film which prevents adhension between laminas of thermoplastic films, namely blocking, and a sandwich, a technology for improving glidability. The lability antiblocking light-settability resin composition of the invention comprises a first component, a second component and silicone compound, wherein the first component includes at least one resin, the second component includes more than one selected from more than one monomer or oligomer, after coating the composition, the resin of the first component is separated due to separation, and minute sagging is formed on the surface.

Description

technical field [0001] The present invention relates to a curable resin composition having antiblocking properties, a hard coat film, a layered structure, and methods for producing them. Background technique [0002] When hard coating is performed on a thermoplastic film such as a PET film, it is wound up and stored in a roll form during the production process. When other layers are stacked on a resin base layer such as a PET film forming a hard coat layer, the layers will be in an adherent state due to adhesive force or chemical force, and when using each layer, it will take a lot of effort to peel off Each layered body is difficult to peel off due to its strong adhesive force, or when it is forcibly peeled off, the layered body is destroyed. [0003] In this case, a back coat is formed by coating and kneading a coating containing particles such as silica of about 1 μm on the other side of the substrate that has not been hard-coated, and by providing unevenness on the surf...
