Problems solved by technology

[0010] However, although the conventional active energy ray-curable coating film has high scratch resistance and high hardness, the friction coefficient of the surface of the cured product is high, and there is a problem that fingers are hindered when sliding

Embodiment 1

[0070]With respect to 100 parts of pentaerythritol triacrylate (trade name: "Aronix (Aronix) M305", manufactured by Toagosei Co., Ltd.) Name "Parleam (Parleam) 6": manufactured by NOF Corporation) 0.5 parts, Iluka (Irgacure) 184 (manufactured by Ciba Specialty Chemicals) as a photopolymerization initiator 5 parts, and 101.5 parts of ethyl acetate was used as a solvent to obtain a curable composition (also referred to as a coating composition or a coating liquid) having a nonvolatile content of 50%.

[0071] This composition was coated on a polyethylene terephthalate film (trade name: "Cosmoshine A4100", manufactured by Toyobo Co., Ltd. ) on the easy-adhesive treatment surface, use a hot air oven to remove the solvent, and use an output of 80W / cm 2 The high pressure mercury lamp with 400mJ / cm 2 UV rays were irradiated to polymerize and harden the coating film to obtain a member with a cured coating film having a coating layer having a dry film thickness of about 6 μm.

Embodiment 2～ Embodiment 3

[0073] 0.5 parts of hydrogenated isobutene (trade name "Parleam (Parleam) 6": manufactured by NOF Corporation) with a number average molecular weight of 350 using 0.5 parts in Example 1 was used in 1.5 parts (Example 2), 3 parts (Example 3 ), except that, a curable composition was obtained in the same manner as in Example 1, and a member with a cured coating was obtained in the same manner.

Embodiment 4～ Embodiment 6

[0075] 0.02 parts (Example 4), 0.1 parts (Example 4) and 0.1 parts (Example 4) of polyethylene (trade name: "Versaflow (Versaflow) LV", manufactured by Shamrock Corporation) with a number average molecular weight of 890 were used as polyolefins. 5), 0.2 parts (Example 6) were substituted for hydrogenated isobutene (trade name "Parleam (Parleam) 6": manufactured by NOF Corporation) having a number average molecular weight of 350, and obtained in the same manner as in Example 1. Components with a hardened coating.

Abstract

The invention provides an active energy ray-curable composition which can form a cured coating with excellent transparency, easy sliding and no easy damage, and a component with the cured coating. The active energy ray-curable composition of the invention comprises the components of: relative to 100 by mass percent of an active energy-ray-curable component (B), and more than 0.01 by mass percent and less than 3 by mass percent of paraffin wax or polyolefin (A) which has a number-average average molecular weight between 320 and 1000 and is liquid at a temperature below 25 DEG C.

Description

technical field [0001] The present invention relates to an active energy ray curable composition and a member including a cured coating film using the composition. Background technique [0002] Compared with thermosetting coating films, active energy ray-curing coating films are rapidly cured, have good productivity, and are also excellent in hardness and scratch resistance, so they are rapidly spreading. [0003] For example, the following technology has been disclosed: by containing a wax (wax) component with a melting point of 125° C. or higher and a particle size of 0.1 μm or less, it is intended to form a coating film that is excellent in scratch resistance or damage resistance and is difficult to slide (Patent Document 1). [0004] In addition, although the technical field is different from that of an active energy ray-curable coating film, Patent Document 2 discloses a technique in which a specific paraffin (paraffin) is included as a means for solving the problems d...
