Abstract
The invention provides a composition for a hard coating, an optical film and a display device using the same. The composition contains dendrimer compound (A), a photopolymerisable compound (B), a photopolymerisable initiator (C), and a solvent. The composition can reach a proper curing intensity, and ensures the hardness of the hard coating, and also greatly increases warping and flexibility.
Description
Technical field
The present invention relates to hard conating formation compositionss, the blooming employing it and image display device.
Background technology
In recent years, liquid crystal indicator (liquid crystal display) or organic light-emitting display device are employed
The thin-type display device of panel display apparatus such as (organic light emitting diode display) receives publicity.Special
Not, these thin-type display devices are realized in the form of touch panel (touch screen panel), are not only intelligent handss
Machine (smart phone), flat board (tablet) pc, and until various wearable devices (wearable device), so that
It is widely used in the various smart machines (smart device) that the property taken is characterized.
Display device based on these portable touch panels, in order to protect display pannel from cut,
Outside impact, possesses display protection window film, all using display in the case of nearly all on display pannel
With strengthens glass as window film.Display strengthens glass is than common glass thin, but has high intensity and damage resistant
Feature.
But, the weight of strengthens glass is big, is not only not suitable for the lighting of portable equipment, and rushes for from outside
Hit fragility, the property (unbreakable) therefore realizing being difficult to damage is difficult, in addition cannot bend to more than certain level.Cause
This, strengthens glass is not suitable as the flexibility with flexible (bendable) or foldable (foldable) function
(flexible) raw material of display.
Recently, for guaranteeing there is while flexibility and impact resistance intensity, the scratch-resistant being equivalent to strengthens glass
Optics plastic cover, carried out positive research.Usually, use as the optics compared with strengthens glass with flexibility
The raw material of the front cover of transparent plastic, has polyethylene terephthalate (pet), polyether sulfone (pes), poly- naphthalenedicarboxylic acid second two
Alcohol ester (pen), polyacrylate (par), Merlon (pc), polyimides (pi) etc..But, these high molecule plastic substrates
Compared with the strengthens glass as display protection window film, in terms of hardness and scratch-resistant, not only show insufficient thing
Property, and impact resistance is also insufficient.Therefore, carried out will by these plastic bases be coated with composite resin composition thus
Supplement the various trials of required physical property.
Thus, plastic basis material film arranges hard conating and ensure that high rigidity.For common hard conating, using by wrapping
The resin of the functional group containing light-cured type and the compositionss of firming agent or curing catalysts and other additives composition, especially
Ground, in the case of the composite resin of high functional group, is applied on optics plastic basis material film, can be used as hardness and scratch-resistant
The display protection form that trace improves uses.
But, the composite resin of general light-cured type, not only it is difficult to be equivalent to the high rigidity of strengthens glass, and
Significantly there is curling (curl) phenomenon that contraction during solidification causes, in addition flexibility is also insufficient, therefore has and is not suitable for
With the shortcoming acting on the protection window film being applied to flexible display.
Plastic base is disclosed in KR published patent 2013-74167 (patent documentation 1).

Content of the invention
Invention problem to be solved
Obtain it is an object of the invention to provide can manufacture and can realize high rigidity and flexibility and crimping simultaneously
The hard conating formation compositionss of the hard coat film of suppression.
It is further an object that being provided with being formed the light of the hard conating being formed with compositionss by above-mentioned hard conating
Learn film.
And then, it is an object of the invention to provide possessing the image display device of above-mentioned blooming.
