To the hardened coating film face of the component with hardened coating film, use Ke Limensi (Klemens) formula scratch hardness test machine (pattern: HA-301, machines industry (TesterSangyo) company manufactures) measure with load 750g according to Japanese Industrial Standards (JapaneseIndustrialStandards, JIS) K5400.
(scuff resistance)
The square pad (pad) of 1 square centimeter of the Steel Wool installing #0000 (steelwool) is placed on the hardened coating film face with the component of hardened coating film, after coming and going 10 times with load 500g, visual assessment outward appearance, measures the number of scar.
(haze value, full light transmittance)
Haze meter (HazeMeter) (pattern: NDH2000, Japanese electricity Se company manufactures) is used to measure the haze value (Hz) of the component with hardened coating film and full light transmittance (T.t.).
(mensuration of kinetic friction coefficient)
For the hardened coating film face of the component with hardened coating film, load be 200g, draw speed is 500mm/min, minute is 60 seconds, measure under temperature is 25 degree, to measure number of times be the condition of 5 times, measure the kinetic friction coefficient in plane pressure head and hardened coating film face, obtain the simple mean value of 5 measured values.
(sliding of finger)
Forefinger to be put down gently on the hardened coating film face of the component with hardened coating film and double rubs 10 times, evaluate sliding.
Zero: few to the resistance of finger, can easily slide.
×: there is resistance to finger, be difficult to slide.
Shown by the result of table 1, for use embodiment 1 ~ embodiment 10 curable adhensive compositions with hardened coating film component for, the excellent and balance such as the transparency, scuff resistance, pencil hardness, sliding is well.Therefore, these components with hardened coating film can suitably need in the purposes of painting property, the transparency and sliding firmly for indicating meter, touch-screen, building materials etc.
In contrast, do not containing in the comparative example 1 of sliding imparting agent (A), although painting property is good firmly for the scuff resistance of hardened coating film, pencil hardness etc., frictional coefficient is high, and the sliding of finger is not enough.
Be in the comparative example 2 of the Parleam of 280 containing number average molecular weight, although painting property is good firmly for the scuff resistance of hardened coating film, pencil hardness etc., frictional coefficient is high, and the sliding of finger is not enough.
Be in the comparative example 3 of the Parleam of 1200 containing number average molecular weight, the surface of the component with hardened coating film confirm drop, cannot evaluate.
Respectively containing number average molecular weight be 2100,2500 poly comparative example 4, comparative example 5 also identical with comparative example 3, the surface of the component with hardened coating film confirms drop, cannot evaluate.
When containing number average molecular weight being 3200 poly comparative example 6, curable adhensive compositions is separated, and cannot make the component with hardened coating film.
Be in the comparative example 7 of the solid polyethylene compound of 900 containing number average molecular weight, although painting property is good firmly for the scuff resistance of hardened coating film, pencil hardness etc., haze value is high and opaque, and frictional coefficient is high, and the sliding of finger is also not enough.
Comparative example 8 containing 5 parts of Parleams, containing in 5 parts of poly comparative examples 9, all on the surface of the component with hardened coating film, confirm drop in the same manner as comparative example 3, cannot evaluate.
Namely learn, by meeting as the paraffin of sliding imparting agent (A) and alkene the condition that (i) is liquid at 25 DEG C, and satisfied (ii) is set as specific mass range relative to active energy ray hardening compound (B) 100 mass parts, and then number average molecular weight is set as all conditions of specific scope by (iii), the transparency can be provided excellent and not easy damaged and then have the hardened coating film of excellent finger sliding concurrently.
[ utilizability in industry ]
Active energy ray curable adhensive compositions of the present invention may be used for all purposes for giving sliding.Such as, can suitably for giving sliding to blooming component.In addition, may be used for the camera lens in the most surface portion to various plastic molded article, photographic camera, the eyeglass of glasses, the window glass of buildings or vehicle etc. and various print surface separately and give identical function.And then, also may be used for giving sliding to Wood member surface.

Claims (2)

1. an active energy ray curable adhensive compositions, relative to active energy ray hardening compound (B) 100 mass parts, with the scope more than 0.01 mass parts, below 3 mass parts containing paraffin or polyolefine (A), the number average molecular weight of described paraffin or polyolefine (A) is more than 320 and less than 1000, and is liquid at 25 DEG C.
2. the component with hardened coating film, it is being selected from going up at least partially of at least one component in glass, plastics, metal, Wood member and paper, arranges the hardened coating film formed by active energy ray curable adhensive compositions as claimed in claim 1 and form.
