No. 2010/095680th, [patent documentation 2] International Publication
In recent years, as the various indicating meters in smart mobile phone (smartphone), portable terminal, PC (personal computer), household appliances etc., touch-screen (touch screen panel) starts universal rapidly.Therefore,, for the most surface of touch-screen, require transparency excellence and there is the scuff resistance of height or high hardness, and further requiring the characteristic that finger sliding is good.
But although former curable with actinic energy ray film has the scuff resistance of height or high hardness, the frictional coefficient on hardening thing surface is high, has the problem of being obstructed while making finger sliding.
The object of the invention is to solve the problem of described prior art, a kind of active energy ray curable adhensive compositions is provided, and described active energy ray curable adhensive compositions can form that the transparency is excellent and finger sliding (the low characteristic of resistance while making finger sliding) excellent and the hardened coating film of easy damaged not.
Summary of the invention
The present invention relates to a kind of active energy ray curable adhensive compositions, with respect to active energy ray hardening compound (B) 100 mass parts, contain paraffin or polyolefine (A) with the scope more than 0.01 mass parts, below 3 mass parts, the number average molecular weight of described paraffin or polyolefine (A) is more than 320 and below 1000, and at 25 DEG C, is liquid.
The present invention relates to a kind of member with hardened coating film, it is being selected from least a portion of at least one member in glass, plastics, metal, Wood member and paper, the hardened coating film being formed is set forms by described active energy ray curable adhensive compositions of the present invention.
[effect of invention]

The member with hardened coating film of embodiment 1~embodiment 10 and comparative example 1~comparative example 10 is carried out to following evaluation of physical property, will the results are summarized in table 1.
(pencil hardness)
To the hardened coating film face of the member with hardened coating film, use Ke Limensi (Klemens) formula scratch hardness test machine (pattern: HA-301, machines industry (Tester Sangyo) company manufactures) measure with load 750g according to the K5400 of Japanese Industrial Standards (Japanese Industrial Standards, JIS).
(scuff resistance)
The square pad (pad) of 1 square centimeter of Steel Wool (steel wool) that #0000 has been installed is placed on the hardened coating film face with the member of hardened coating film, come and go after 10 times with load 500g, visual assessment outward appearance, the number of mensuration scar.
(mist value, full light transmittance)
Use haze meter (Haze Meter) (pattern: NDH2000, Japanese electricity Se company manufactures) to measure mist value (Hz) and the full light transmittance (T.t.) with the member of hardened coating film.
(mensuration of kinetic friction coefficient)
For the hardened coating film face of the member with hardened coating film, at load for 200g, draw speed being that 500mm/min, minute are 60 seconds, to measure temperature be 25 degree, measuring number of times is under the condition of 5 times, measure the kinetic friction coefficient of plane pressure head and hardened coating film face, obtain the simple mean value of 5 measured values.
(sliding of finger)
Forefinger put down gently on the hardened coating film face of the member with hardened coating film and come and go friction 10 times, evaluating sliding.
Zero: the resistance to finger is few, can easily slide.
×: finger is had to resistance, be difficult to slide.
Result by table 1 shows, for use embodiment 1~embodiment 10 curable adhensive compositions with for the member of hardened coating film, the excellences such as the transparency, scuff resistance, pencil hardness, sliding and balance are good.Therefore, these members with hardened coating film can suitably need the purposes of hard painting property, the transparency and sliding for indicating meter, touch-screen, building materials etc.
With respect to this, not containing in the comparative example 1 of sliding imparting agent (A), although the hard painting property of scuff resistance, the pencil hardness etc. of hardened coating film is good, frictional coefficient is high, the sliding deficiency of finger.
Contain number average molecular weight and be in 280 the comparative example 2 of Parleam, although the hard painting property of scuff resistance, the pencil hardness etc. of hardened coating film is good, frictional coefficient is high, the sliding deficiency of finger.
Contain number average molecular weight and be in 1200 the comparative example 3 of Parleam, on the surface of the member with hardened coating film, confirm drop, cannot evaluate.
Contain respectively number average molecular weight and be 2100,2500 poly comparative example 4, comparative example 5 also identical with comparative example 3, on the surface of the member with hardened coating film, confirm drop, cannot evaluate.
Contain number average molecular weight and be in 3200 the situation of poly comparative example 6, curable adhensive compositions separates, and cannot make the member with hardened coating film.
Contain number average molecular weight and be in 900 the comparative example 7 of solid polyethylene compound, although the hard painting property of scuff resistance, the pencil hardness etc. of hardened coating film is good, mist value is high and opaque, and frictional coefficient is high, and the sliding of finger is also not enough.
The comparative example 8 that contains 5 parts of Parleams, contain in 5 parts of poly comparative examples 9, all similarly on the surface of the member with hardened coating film, confirm drop with comparative example 3, cannot evaluate.
Learn, meet (i) by the paraffin as sliding imparting agent (A) and alkene is the condition of liquid at 25 DEG C, and meet (ii) and be set as specific mass range with respect to active energy ray hardening compound (B) 100 mass parts, and then (iii) number average molecular weight is set as to all conditions of specific scope, can provide the transparency excellent and easy damaged and then have the hardened coating film of excellent finger sliding concurrently not.
[ utilizability in industry ]
Active energy ray curable adhensive compositions of the present invention can be for wanting to give all purposes of sliding.For example, can be suitably for giving sliding to blooming member.In addition, can give identical function for window glass and the various print surface separately of eyeglass, buildings or the vehicle etc. of the camera lens of the most surface portion to various plastic molded articles, photographic camera, glasses.And then, also can be for giving sliding to Wood member surface.

Claims (2)

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