Embodiment
The present invention relates to following window substrate and the touch panel with the window substrate, the window substrate possesses window
Mouth substrate and the non-conducting light-shielding pattern being formed in the non-display portion in one face of window substrate, the non-conducting screening
Light pattern has：Relief pattern comprising pearlescent pigment；Cover the relief pattern and form the tone pattern on flat surface
Layer；And the light shield layer on the tone patterned layer top, therefore, the window substrate, which can possess, can show third dimension and identification
The non-display portion of the excellent pattern of property, and it is suitable for the application of the substrate in large area.
In the present invention, so-called third dimension refers in addition to by three-dimensional conformation identification, also included in from front and
Confirm discrepant concept in the shape of inclined-plane identification.
Hereinafter, present invention will be described in detail with reference to the accompanying.Wherein, the following accompanying drawing appended by this specification is for this hair of example
Bright preferred embodiment, for being easier to understand together with the content with foregoing invention the technological thought of the present invention, therefore, this
Invention should not be construed as being only limited to the item described in above-mentioned accompanying drawing.
＜ window substrates ＞
In fig. 2 it is shown that the outline of the window substrate 100 with non-conducting light-shielding pattern 200 of the present invention is vertical
Straight sectional view.
Non-conducting light-shielding pattern 200 involved in the present invention has relief pattern 210, tone patterned layer 220 and hidden
Photosphere 230.
Relief pattern 210 includes pearlescent pigment, and the shape prominent from the opposite side surfaces for recognizing side to window substrate 100
The sag and swell of state is formed, by forming texture structure in non-conducting light-shielding pattern 200, so that in non-conducting shading figure
D structure is provided in case 200.The pearlescent pigment of glittering is formed with relief pattern, so as to by with tone pattern described later
220 reflectivity and the difference of refractive index, to significantly increase third dimension and texture effect.Target pattern can pass through bumps
The specific form of pattern 210 is formed.
The highly preferred of relief pattern 210 is 2~20 μm.If in above-mentioned number range, can ensure excellent simultaneously
Identity and process.
The pearlescent pigment included in relief pattern 210 is the pearlescent pigment of multiple tone, is to representing natural pearls color, coloured silk
The pigment that the pigment of iridescence, metallochrome etc. is referred to as.Pearlescent pigment used in the present invention is outside not only aesthetic feeling is excellent, and reflection
Rate is high, and the embodiment performance of third dimension and texture is also excellent.
Pearlescent pigment used in the present invention can also have reflecting layer core and be coated with the reflecting layer core
High refractive index layer.For above-mentioned reflecting layer core and the specific material of high refractive index layer, can according to panel tone,
Reflectivity etc., carries out various selection.
As reflecting layer core, for example, mica, sericite, talcum, kaolin, smectite-group clay ore deposit can be enumerated
Thing, tabular titanium dioxide, tripolith, plate-like aluminum oxide, boron nitride, barium sulfate, tabular titania/silica composite oxygen
Compound etc., these compositions not individually or can mix two or more use.
High refractive index layer can include TiO2、ZrO2、Sb2O3、ZnS、SnO2, ZnO etc., these compositions can also be individually
Or mix two or more use.
The refractive index of high refractive index layer is preferably 2.4~3.0.If in above-mentioned number range, pearly-lustre face can be represented
The excellent reflectivity of material and aesthetic feeling.
The average grain diameter of pearlescent pigment used in the present invention is preferably 5~15 μm.
If using the pearlescent pigment of the average grain diameter with above-mentioned number range, the storage stability of composition is carried
For hardening is improved with the masking problem of light, so as to help that good pattern can be formed.If average grain diameter is not enough
5 μm, then identity (light characteristic or pearl sense) be likely to decrease, if it exceeds 15 μm, it is likely that in coating composition
Generation spray nozzle clogging, or the uniformity of coated face reduce and can not be readily formed pattern.
Pearlescent pigment involved in the present invention includes 0.2~2 weight % amount relative to the gross weight of relief pattern 210.
If amount is less than 0.2 weight %, identity (light characteristic or pearl sense) may be reduced, if it exceeds 2 weight %, then
Process may be reduced.
Relief pattern 210 as needed, in addition to above-mentioned pearlescent pigment, can also be included within the scope of the invention
Colouring agent known in the art, for example, dyestuff and pigment.
Tone patterned layer 220 is the layer for covering relief pattern 210, when from coming from identification side, due to by relief pattern
Reflection in the reflection for the incident light that the textured pattern of 210 sag and swells embodied is produced and refraction and tone patterned layer 220
Phenomenon, therefore with the function that third dimension and texture are assigned to the pattern based on relief pattern 210.
Tone patterned layer 220 can be made up of, now, each layer can to embody desired tone multiple dyed layers
With mutually different tone.For example, by forming multiple layers with mutually different tone, additionally it is possible to embody the color of colour mixture
Adjust.
Tone patterned layer 220 can be formed by can carry out photolithographic non-conducting tone pattern and formed with composition,
It is aftermentioned to this.
Light shield layer 230 has following function：By forming flat surface on the top of tone patterned layer 220 so that it
Bonding process afterwards can be easily performed, the bumps that the masking of protection metal line etc. and tone patterned layer 220 are covered
Pattern 210 so that the tone of target is embodied on non-conducting light-shielding pattern.Therefore, it is possible to identical with tone patterned layer 220
Tone, or with different tones.Preferably, in order in the screening effect and tone patterned layer 220 of metal line
The effective embodiment of tone, it is the Hue layer of black.
The thickness of light shield layer 230 is preferably 1~10 μm.If thickness is less than 1 μm, shielding may be reduced, if super
10 μm are crossed, then process may be reduced.
Window substrate of the invention with non-conducting light-shielding pattern as described above can possess with third dimension simultaneously
Non-display portion with the excellent pattern of identity.
